Gigabit Ethernet Port Scales WAN Bandwidth

When you are ready to make the move from copper to fiber bandwidth levels or upgrading an OC-3 SONET service, you are faced with a choice. What level of bandwidth do you install?

Why not give yourself flexibility for the future and the opportunity to pay only for what you need right now? This is what a Ethernet port strategy can do for you.

Scalability is a new idea in business telecom services. When you install a T1 line, it requires a very specific T1 interface that include a CSU/DSU circuit unique to the T1 line specifications. Upgrade to a T3 line (DS3 bandwidth) and you’ll find that you can’t just plug that T3 into your T1 router. The interface is completely different. Even the connecting cable is different. With DS3 you are looking at a pair of coaxial BNC connectors that don’t support any other service. Now, make yet another move on up to OC-3 service. Your router interfaces for T1 and T3 are no good. You need a fiber input to your router.

It doesn’t get any better when you start moving up the fiber optic hierarchy. You can’t just plug OC-12 or OC-48 into an OC-3 port and have everything spring to life. They are different services requiring modifications. You’ll likely need a new interface card and programming changes to your router. If you have a managed router, that probably means a truck roll to your premises to swap out the CPE (Customer Premises Equipment).

In the back of your mind, you must suspect it doesn’t have to be this way. Those new PCs have NICs (Network Interface Cards) labeled 10/100/1000 Mbps. That means that you can plug them into any LAN running at up to 1 Gbps and they’ll work just find. Even the connector takes the same RJ-45 patch cord. Wouldn’t that approach be far superior for WAN connections too?

This is the beauty of Carrier Ethernet, which includes Metro Ethernet, MPLS network access and long haul point to point connections. Ethernet beyond the LAN has been designed to be as flexible as Ethernet on the LAN.

One of Ethernet’s best features as a bandwidth service is ease of scaling. If you are running 50 Mbps service and find your needs have increased so that you now need 100 Mbps, you can just call up your service provider and request an upgrade. In a matter of hours or a day or two at the most, your WAN network speed will double. In that time, no one has knocked on the door with a new router under their arm. In fact, you haven’t seen anyone from the service provider. It was all done over the phone.

There is a trick to making this work. The magic is all in the installed Ethernet port. When you order Ethernet service, make sure that you have a port installed that will support the highest bandwidth you reasonably expect to be ordering down the road. Most ports are the standard Ethernet speeds of 10 Mbps, 100 Mbps and 1,000 Mbps. It’s also possible to get a 10,000 Mbps or 10 GigE port with a suitably fast managed router if your needs are that high.

With Ethernet over Copper, you are probably looking at a 100 Mbps Ethernet port at most. Be sure you know just what your maximum speed will be, because EoC is distance limited and requires more copper pairs as speed increases. Ask what bandwidth your installation will support compared to what you are ordering initially.

With Ethernet over Fiber, it likely makes sense to install a Gigabit Ethernet port. The fiber itself has more capacity that you are ever likely to employ. The speed of the port will be the limiting factor, along with the capability of the carrier’s equipment that feeds that port. Once again, it is smart to plan for the future but buy for today. Get the bandwidth you need now, but be sure that the system is engineered to allow for fast and easy upgrades as you need them. That will be especially handy if you get hit with a sudden increase in traffic or a need to support massive amounts of video or enormous file transfers that you didn’t anticipate.

Are you ready for a bandwidth upgrade, but unsure of what commitment to make? Give yourself some breathing room with a Gigabit Ethernet port and the ability to scale up your bandwidth as needed. Get prices and availability of Ethernet ports and line speeds now.

Internet Wholesale Bandwidth Options

There are two types of organizations that buy Internet bandwidth. Most are end users. They want the access for their employees. The others are resellers. They take large Internet connections and divvy up the bandwidth to hundreds or thousands of individuals and businesses. These are Internet Service Providers (ISPs) looking to buy at wholesale and sell at retail.

The largest networks in the world, called Tier 1, don’t purchase Internet access. They are part of the core network itself. Those major world wide networks exchange traffic on basis of equals called peering. Each network gets as much traffic as it sends to the others, so all benefit and no money is exchanged.

Everyone else has to get to the Internet by accessing one of these Tier 1 networks. The next level down, the Tier 2 networks, are also very large Internet service providers. Since they don’t have the enormous global traffic to participate in peering, they purchase what is called IP Transit. This is Internet access sold on a per Megabit per second per month basis.

Smaller Tier 3 networks can purchase IP Transit from Tier 2 networks, if they are large enough to have an assigned AS or Autonomous System number (ASN) to identify them as part of the Internet. Large scale ISPs fall into this category as well as some large corporations and other organizations.

Local and regional Internet Service Providers, including WISPs (Wireless Internet Service Providers), buy DIA or Dedicated Internet Access. DIA connections are like point to point private lines, except that one end connects to the Internet. Other private line characteristics still apply. The bandwidth provided is completely dedicated to the ISP and not shared with anyone else. There are generally SLAs or Service Level Agreements that spell out characteristics such as maximum latency, jitter and packet loss as well as time to respond to outages and time to make repairs.

Dedicated also means that there are no extra charges for heavily loading the line. You can use the entire capacity of the circuit in both directions or only some of it. The price is the same.

The smallest DIA service is usually a T1 line running at 1.5 Mbps. This is a symmetrical service, meaning 1.5 Mbps upload and 1.5 Mbps download. Usually the download path is much heavier loaded than the upload path for typical Internet access. If fact most consumer Internet access is sold with 5x to 10x higher speeds on download than upload. For business users, upload speeds can be important when transferring large files to remote backup sites and servers within colocation centers.

Obviously, T1 lines can’t serve a large user base but they work great for WiFi hotspots and rural or subdivision WISP service where signed-up customers number in the dozens, not hundreds. A nice feature of T1 lines is that they can be bonded by adding more lines to double, triple and quadruple bandwidth up to about 10 or 12 Mbps. The other nice feature of T1 lines is that they are available where other line services don’t reach. If you can get business telephone system into a facility, you can probably get T1 DIA service.

The next increment in traditional telecom bandwidth is DS3, also called T3 lines. This service runs at 45 Mbps which is large enough for a good size service provider to offer competitive bandwidth. Beyond that, SONET fiber optic services include OC3 at 155 Mbps, OC12 at 622 Mbps and OC48 at 2.5 Gbps are very popular.

A strong competitor to T-Carrier and SONET bandwidth is Carrier Ethernet. It comes in two flavors, Ethernet over Copper (EoC) typically from 1 to 50 Mbps and Ethernet over Fiber (EoF) from 10 Mbps to 10 Gbps. In a some metropolitan areas, you can also get EoFW or Ethernet over Fixed Wireless at DS3 and Fast Ethernet speeds. Where available, Carrier Ethernet tends to have considerably better pricing than other services.

Do you resell Internet access to other ISPs or end users? If so, see if you can get better wholesale pricing on Dedicated Internet Access and IP Transit services.

A Dedicated Line Between Offices

Many companies have two offices that they would like to link. These offices may be in the same city, across the country or even in different countries. What options are available to do this and what services can you get?

The traditional telecom services link between offices is the dedicated private line. T1 lines have been long used for this purpose because they are almost universally available and often the lowest cost solution. A point to point T1 data line will give you 1.5 Mbps of symmetrical bandwidth. That means 1.5 Mbps upload and 1.5 Mbps download. Symmetrical bandwidth is important when used to link business locations because you’ll have similar traffic levels going in both directions. That differs from the Internet where downloading predominates.

Two other characteristics of T1 lines are important to consider. One is that this is a private line. It’s like having a pair of wires connected at one building and the opposite end of the wires connected at the other building. In fact, for local T1 lines that may be close to the way it is wired up. Over longer distances, your T1 service will probably be multiplexed on a higher bandwidth connection, likely a fiber optic network, for the long haul portion of the interconnection. Regardless, you have a private service that is difficult for anyone to intercept. If you want to ensure the ultimate in privacy, you have the option to encrypt your transmissions on that line.

The other important characteristic of T1 lines is that the bandwidth is dedicated to your usage. You can load it up with two-way traffic 24/7 or just use it when you want to transfer a file. Whatever doesn’t get used just sits there waiting for you. You’ll never run into the situation where your service slows down because some other company is downloading HD videos from the Internet. This also means that there are no usage restrictions. Your T1 line can be used lightly or continuously and your bill at the end of the month will be the same.

T1 lines are available in both data and voice configurations. The voice configuration, called T1 telephone, can transport 24 separate phone conversations. A variation, T1 PRI or ISDN PRI transports 23 phone lines plus a switching and information channel used to provide Caller ID.

What if you need more bandwidth? The next step up with traditional telecom services is DS3 at 45 Mbps, followed by SONET fiber optic including OC-3 at 155 Mbps, OC-12 at 622 Mbps, OC-48 at 2.5 Gbps and OC-192 at 10 Gbps.

You also have the choice of Ethernet line services from typically 10 Mbps on up to 10 Gbps as point to point dedicated connections. Ethernet tends to be lower in cost than traditional services and more scalable. In other words, it’s easier to increase line speed with Ethernet than with T-carrier or SONET.

Another option to link offices, especially over long distances like coast to coast or internationally, is MPLS networking. MPLS networks are highly secure, well engineered to provide committed bandwidth levels, and reasonably priced. It may well be cheaper to order a last mile connection at each end and let the MPLS network handle the long haul than specify a dedicated point to point line service. You’ll get similar performance either way.

Are you looking to establish a dedicated line between offices, perhaps with one of them overseas? Compare options and prices online for T1, DS3 and Ethernet up to 1 Gbps. Note that US to international destination connections will require some manual effort to price, with quotes delivered promptly to your specifications.

Metro Ethernet vs MPLS Networking

In addition to dedicated Internet access, many companies also need point to point private lines and/or multipoint network connections. The classic way to accomplish this has been to lease private lines to create your own wide area network setup. There are two other methods available that can give you the same results for considerably less cost.

Metro Ethernet service has been seen as a way to get point to point connections in town at a lower cost than leasing dedicated line services, such as DS3 or OC3. This service is called E-Line or Ethernet Line. It’s is standardized by the MEF (Metro Ethernet Forum) so you can compare E-Line services from multiple vendors and know that you are getting the same product.

What’s the difference between ordering an E-Line connection at 50 Mbps versus a DS3 dedicated line at 45 Mbps? When you order a dedicated line, you can envision having a pair of wires going from your headquarters, through a cross-connect at the telco central office and then out to your branch office. That’s probably true for a T1 line provisioned on two twisted copper pair. When you get into DS3 and higher bandwidths, your connection will probably be carried via SONET fiber optic service using an add/drop multiplexer. Along the way, your signal will be traveling with many other who share the same fiber strand.

Here’s what’s important: Unless you actually go out and construct or lease the copper or fiber transmission medium, you are using a shared or multi-tenant service. It’s true with Metro Ethernet and MPLS Networks. It’s also true with dedicated line services. The difference is that MPLS and Metro Ethernet are packet switched networks while T-Carrier and SONET services are circuit switched. With circuit switching, the circuit is used only for your traffic on a single path that is “nailed up” for the time you hold the lease. With packet switching, other traffic can share common paths through the network. That does two things. It lowers the price of the service and it makes some additional services possible.

Metro Ethernet has both an Ethernet Private Line and Ethernet Virtual Private Line service available. The virtualization means that you only need to install one Carrier Ethernet port to have connections with two or more locations. The actual physical line is shared among your own traffic. You may have ten or more branch offices, retail stores or other locations in town. With EVPL you can have point to point connections to many locations coming in through one UNI (User Network Interface).

Here’s another service you can get with Metro Ethernet. It’s called E-LAN or Ethernet LAN service. This is a meshed network that lets many locations all communicate without going through a single point. E-LAN is popular for interconnecting a company’s many independent LANs in the same geographical area. This can be done at the layer 2 level so that the entire network looks like one giant bridged network.

Interconnecting multiple locations is also the domain of MPLS or Multi-Protocol Label Switching networks. Many of these have regional, national or even international service footprints so that all of your far flung locations can interact on the same network. MPLS may be the solution of choice for covering geographical areas larger than a single city and its suburbs. MPLS can also be used to create point to point connections for only two locations. When those locations are located on opposite coasts or in different countries, MPLS can be a better deal than Ethernet Line service or point to point dedicated line services.

Since Ethernet and MPLS services overlap to some extent, what criteria do you use to make a choice? I’d recommend getting price quotes for these, plus dedicated lines, and comparing the total lease cost for the same bandwidth and other requirements. You can get networking bandwidth quotes from multiple service providers quickly and easily using the GeoQuote tool. In fact, many line services to 1 Gbps quote automatically online.

EarthLink Means Business With 10 GigE Fiber

Most of us remember EarthLink from land rush days of the Internet when anyone and everyone just had to get on the net now, and dial-up 56K service was the best you could get. EarthLink is still a viable ISP for consumers with both dial-up and broadband access available. But there’s another side to this famous company. EarthLink Business is a facilities-based competitive carrier serving everything from SMB to enterprise needs with over 28,000 miles of fiber installed and more in the works. They’re in the process of installing two new 10 Gigabit Ethernet fiber rings in Ohio and Eastern Pennsylvania. There’s also a new high speed fiber route going in between Philadelphia and Pittsburgh.

What’s with all the new high-bandwidth construction by EarthLink and others? In case you haven’t heard, business is automating like crazy and heading to the cloud. The enduring slowdown in economic expansion has given corporations a chance to re-examine their operations and re-engineer for what they’ll need in the future. One thing they’ve found is that office automation can be as big an enabler of employee productivity as the factory automation of decades past. That means more computers, more processing and more communication between business sites, vendors, customers and remote employees. Any business that has outsourced overseas has found that a key to making this work efficiently is to tie together the far flung operations as if they were right next door. You can’t do that physically, of course, but you can do it virtually if you have the right networking.

The cloud is also seen as a game changer in a world where it’s hard to predict what resources you’ll need next season or even next month. Traditional in-house data center construction is a capital and time intensive approach. If what you are doing will run just as well in a remote data center, you gain the advantages of avoiding capital investments and buying what you need by the moment with the knowledge that additional resources are always available when you need to scale up. Scaling up is the expected path as a company grows over the years. Now you have the option to scale up and scale down as business fluctuates so you never have idle resources running up expenses.

The one thing that process automation, outsourcing and cloud operations have in common is that they are bandwidth intensive. That bandwidth was fairly easy to come by when everything was on your local network. Now you need the same big conduit going between cities, across the country and perhaps overseas.

SONET is the proven core network technology for fiber optic WAN networks. You can certainly run legacy OC3, OC12 and OC 48 fiber optic connections for your business connectivity. But today it’s Ethernet services that are hot. No problem. Ethernet runs over SONET just fine. In fact, many advertised Ethernet fiber optic networks are really running SONET at their core. OC-192 is a good match for 10 Gigabit Ethernet, with a special WAN-PHY protocol designed especially to transport 10 GigE on a OC-192 optical carrier.

EarthLink is expanding their nationwide fiber network and their suite of business telecom services that include MPLS networking, full and fractional DS3, EVDO 3G wireless, SIP trunking and Metro Fiber Ethernet. They added three new data centers in Rochester, NY, Marlborough, MA and Columbia, SC with 10 Gigabit fiber rings connecting each location to the network backbone. Such high bandwidth connections allows them to offer real time data replication and cloud services to interested companies.

Is your business re-engineering for higher productivity and more agile operations? If so, you may benefit from some of the new cloud services and high bandwidth network connections that have become recently available. Even your current operations can cut costs while retaining the same performance with competitive telecom services.

GigE and FastE Bandwidth Services

Bandwidth upgrades are a matter of course these days. Many companies are moving from T1 line speeds at 1.5 Mbps up to 3x3 Mbps or 10x10 Mbps Ethernet. Often there is little or no additional cost involved in doing so. But what if these bandwidth levels are still to low for your needs? Are there any opportunities at the 100 to 1000 Mbps level?

Carrier Ethernet is now the service to pursue at medium and high bandwidth speeds. These service levels have been dominated by DS3 or T3 lines at 45 Mbps and SONET OCx for higher line speeds over fiber optic cable. Ethernet bandwidth has a cost advantage for this need and also provisioning flexibility.

It’s common knowledge that low and mid-band Ethernet services are readily available over twisted pair copper wiring. In other words, the same telco wires that you currently use for analog business phone lines and T1 lines can also be used to transport Ethernet protocol. The service requires specialized equipment at each end and multiple copper pairs. This is Ethernet over Copper. Bandwidth levels vary from 1 Mbps on up 100 Mbps and beyond. A 200 Mbps service is available in some areas and a new 400 Mbps asymmetrical Internet access is being rolled out.

Most companies opt for Ethernet as a last mile connection to the Internet, metro or wide area MPLS network with bandwidth up to 50 Mbps. This is a direct replacement for their existing copper wire T1, bonded T1 or DS3 connections. By moving up the speed range to 100 Mbps to 400 Mbps, Ethernet can directly replace such fiber optic services as OC-3 at 155 Mbps and perhaps OC-12 at 622 Mbps.

All of this is done over up to 8 bonded copper pair at distances that don’t exceed a few thousand feet to a few miles from the telco central office. This is no problem in densely populated business districts, but as you move out into the burbs, small cities and rural areas, service becomes less available. Ethernet over Copper has a definite distance limitation.

Fast Ethernet at 100 Mbps may be available over copper, but Ethernet over Fiber is a better bet. The beauty of fiber is that once you have it installed and your building is “lit”, just about any bandwidth is possible. That includes FastE, of course, at 100 Mbps, GigE or Gigabit Ethernet at 1,000 Mbps and 10 GigE or 10 Gigabit Ethernet at 10,000 Mbps.

Ethernet over Fiber is available from traditional telephone companies, but it is also available from competitive carriers who have built their own IP-core regional and national networks with Ethernet as a standard service. These companies can bring Ethernet right to your building without having to lease any telephone company facilities. This gives them the ability to offer more bandwidth for less money. You may save half or more for equivalent service levels at the higher bandwidths.

A new wrinkle is Ethernet over Fiber offered by Cable MSOs. This fiber was bought and paid for by the Cable Television industry, but has so much extra bandwidth available that these companies are offering access to their fiber optic networks to businesses and other organizations that need anywhere from 10 to 1000 Gbps. That includes Fast Ethernet and Gigabit Ethernet at prices that are up to half the cost of other fiber providers.

The options are many and the prices are very attractive right now. There is lots of bandwidth to go around, which may not be true when the economy takes off again. If you need to speed up your networks, you can lock in some excellent deals. Check prices and availability for GigE and FastE bandwidth services appropriate for your business location.

WAN Computer Network Connections

Computer networks are often categorized as LAN, MAN and WAN. The LAN is your local network. You design and maintain it to meet your specifications. Or, you hire a contractor to do this. When you need to connect your LAN to another LAN across town or around the world, you enter the realm of the MAN and WAN. Here’s a quick look at what’s available in the way of metro and long haul connections.

The difference between the MAN and the WAN is largely a matter of degree. The MAN is a Metropolitan Area Network. As the name suggests, MAN services are limited to a particular city or city and suburbs. It’s the right connectivity for companies that have multiple offices in the same city, a main facility and a remote data center across town, a factory or warehouse in an industrial park plus some satellite offices. Hospitals and their associated medical centers are good candidates for MAN service, especially higher bandwidths for medical image transmission.

A difference between the LAN and MAN is that you own your LAN and buy services from the MAN. A Metropolitan Area Network is typically privately owned and offers services to numerous clients. The network operator manages bandwidth and security to ensure that every customer feels like they have the network all to themselves.

Most MANs are organized as SONET rings that encircle the metropolitan area. A SONET ring is actually two fibers with the same traffic running in opposite directions. One is the primary service and the other is the backup. This is done to ensure reliability. If one fiber or its associated equipment experiences a failure, service is automatically switched to the other fiber in the ring within 50 milliseconds. SONET has designated service levels at OC-3 (155 Mbps), OC-12 (622 Mbps), OC-24 (1.24 Gbps), OC-48 (2.49 Gbps), OC-192 (9.95 Gbps) or OC-768 (39.8 Gbps). You may also be able to get DS3 service multiplexed onto an OC-3 service for transport across town.

Newer metro networks may offer Carrier Ethernet instead of SONET. Ethernet is highly scalable from as low as 1 Mbps on up through 10 Gigabit Ethernet. Popular MAN service levels are 10 Mbps, 100 Mbps, and 1,000 Mbps or GigE. An advantage of Ethernet is that changes in service level can be accomplished faster than with traditional SONET. You can also get layer 2 Ethernet connectivity, such as E-Line and E-LAN, to connect your LANs at other locations into one large bridged network. The MAN itself may have an IP core or be running as Ethernet over SONET to use existing facilities.

Think of the WAN as a very large MAN and you probably won’t be far off. WAN networks may also have SONET rings or IP core networks. They are certainly fiber optic based and often with so many strands that you can lease wavelengths or even dark fibers. Many WAN networks are structured as MPLS or Multi-Protocol Label Switching networks for flexibility. A MPLS network has inherent security due to a propriety routing technology that is not IP. MPLS networks can transport any protocol by encapsulating the packets within the switching labels.

WAN networks may have a regional, national or international footprint. Some are designed with low latency paths that are especially important for financial trading. WAN networks may also peer with other networks of similar size to share traffic. The newest wrinkle is the Ethernet Exchange that exchanges Ethernet traffic without having to first convert it to SONET.

How do you connect to a WAN network? Often you can pick the connection that is both readily available and lowest in cost for your particular application. These range from T1 lines to Ethernet over Copper, Ethernet over Fiber, and SONET last mile connections. In some cases, fixed wireless access is also available. The mix of copper, fiber and wireless access should accommodate just about any need.

Do you have a need to connect your LAN to another facility across town, or to locations in other states or countries? Compare prices and availability of various MAN and WAN connectivity options to meet your requirements.

Gigabit Ethernet vs SONET

With the expansion of video content and moves to cloud services, business bandwidth now easily pushes the Gigabit per second level. This certainly means a move from copper to fiber optic services. But did you know that there are two types of fiber optic bandwidth to choose from? They are SONET and Gigabit Ethernet.

SONET is the original fiber protocol developed by the telephone companies to transport large numbers of simultaneous telephone calls between switching centers and internationally. SONET stands for Synchronous Optical NETwork. There is an international version of this protocol called SDH for Synchronous Digital Hierarchy. Together they are often referred to a SONET/SDH.

SONET’s origins go back to the initial development of digitized telephone conversations and the transmission of these a groups using trunks known as T1 lines. The larger T3 lines can carry the equivalent of 28 T1 lines or a data bandwidth of 45 Mbps. There are no faster copper telco standards. The next step up is OC-3 at 155 Mbps. That’s enough to transport 3 DS3 circuits and, indeed, the protocol is designed to easily multiplex and demultiplex lower level services. When you order a DS3 today, it will be transported most if not all of the way multiplexed into a OC service. A device called an ADM or Add-Drop Multiplexer gets the service on and off the optical network.

You’ve probably guessed that OC stands for Optical Carrier. There are a number of optical carrier levels that include OC-3 at 155 Mbps, OC-12 at 622 Mbps, OC-24 at 1.24 Gbps, OC-48 at 2.49 Gbps, OC-192 at 9.95 Gbps and OC-768 at 39.8 Gbps. When you hear about 10 Gbps SONET, it is an OC-192 service. The 40 Gbps that many carriers use for long haul transmission is OC-768.

What about intermediate rates? Not all levels between 1 and 768 are defined. Others, such as OC-9, OC-18, OC-36 and OC-96 are standardized but not generally offered in service.

SONET/SDH is set up in ring arrangements with two separate fiber strands for each ring. They are redundant circuits, so if one fails the other can pick up the load within 50 mSec.

Ethernet is a completely different protocol developed by the computer industry rather than the telephone companies. It is based on packets rather than telephone channels. Most LAN connected devices have a NIC or Network Interface Card that supports 10/100/1000 Ethernet. That means the device can run at 10 Mbps, 100 Mbps or 1,000 Mbps (1 Gbps). Corporate LANs may now run at 1 Gbps with some parts of the network using 10 Gbps or 10 GigE.

The equivalent of Ethernet in the LAN for local networks is Ethernet WAN or Wide Area Network. Switched Ethernet used for WAN applications is also called Carrier Ethernet. If the service is local to a particular city or metro area, it is often called Metro Ethernet or Metropolitan Ethernet and the network is referred to as a MAN or Metro Area Network.

Like telco services, Ethernet may be delivered over copper or fiber. Twisted pair copper telephone line can be used up to 100 Mbps. That speed is also available over coaxial copper cable through Cable systems. Beyond that, fiber optic connections can deliver 1 Gbps or 10 Gbps for business applications.

Ethernet is designed to be far more scalable than SONET. Instead of ordering a particular service level, such as OC-24, you order an Ethernet port capable of handling a maximum speed, say 1 Gbps. With the port in place, you can pay for Gigabit Ethernet if you need that much, or you can order 250 Mbps or 500 Mbps Ethernet and upgrade quickly and easily when the need arises.

Which fiber optic service should you order? In general, Ethernet is less expensive per Mbps than SONET. Sometimes the price savings can be dramatic. The one sticking point is that you need to have the service installed in your building. You may have one or the other services now or nothing at all. The cost of construction to bring in the right fiber from the right carrier can outweigh the monthly lease costs. You should know, though, that Ethernet can often be carried on SONET and that competitive carriers are hungry to get new buildings on their networks. These factors can affect the availability and pricing of fiber optic services to your building.

Fiber optic build-outs are progressing rapidly and the demand for high speed bandwidth increases. Even if you went out for bids a year ago, the situation may have changed for the better since then. The best thing to do is get new prices and availability for fiber optic bandwidth services for your particular business location.

Business Internet Access Companies

Consumers have variety of ways to gain access to the Internet. Businesses have equivalents to these, plus a some others not available to residential users. Let’s take a look at what’s available for companies with their own business addresses.

The most popular consumer broadband services are DSL and Cable for fixed locations and 3G for mobile use. 4G wireless is starting to become available, with CLEAR promoting it for both fixed and mobile use. Out in the boonies, Satellite broadband brings in a signal that you can’t get with wires. The fastest service, fiber optic, is deployed in selected areas by Verizon’s FiOS. It should also be noted that there are still consumers embracing dial-up access either because of cost or a very limited need for the Internet.

Businesses also have DSL, Cable, 3G and 4G mobile services, and Satellite Internet available to them. Like the consumer versions, you get a price break by sharing a bandwidth pool with other users. That means that the speed you’ll experience at any given time depends on how many other users are on the service and what they are doing.

There are a couple of features that interest business users much more than consumers. One is symmetrical bandwidth. Shared resource Internet access solutions typically offer much higher download speeds than upload speeds. That’s because most people are primarily reading web pages or downloading material such as books, music or movies. A limited upload speed is all you need to send commands to the servers providing this content. Businesses, however, often own the servers as well as use them. If you are sending material up to a server or another user as much as you are receiving such material, then a symmetrical bandwidth evens things out. Symmetrical DSL (SDSL) is typically available to business users but not consumers.

Businesses may also want static IP addresses. These are needed if you are running a server, so that other users on the Internet can easily find it through the DNS system. Normal consumer connections use dynamic IP addresses that are assigned from a pool owned by the Internet Service Provider and change from time to time. Most users have no ideal what IP address they are using and couldn’t care less as long as it works. IT managers, however, may well want static IP addresses for the servers, VoIP and VPN systems on their networks.

Many businesses may find that shared bandwidth causes way too much performance variation for their needs. The solution is dedicated bandwidth services that are generally available for business addresses but not residential users or home offices. These services include T1 lines, Ethernet over Copper, DS3, Ethernet over Fiber, SONET and Fixed Wireless. As business services, these dedicated Internet access solutions also have symmetrical bandwidth with equal upload and download speeds.

The other thing that should be noted about dedicated business bandwidth services is that they often come with SLAs or Service Level Agreements. Unlike the “best effort” offers for consumer grade broadband, a service level agreement spells out performance parameters and remedies if those are not met. Often, the commitment is for availability plus performance characteristics such as jitter, latency and packet loss.

Does your company need new or expanded Internet connectivity, or are you simply interested in seeing if better pricing is available at the bandwidth level you already have? If so, get pricing and availability of bandwidth solutions from a variety of business Internet access companies.

FastE Is The New DS3

Companies that have outgrown their T1 line capacity have traditionally moved up to DS3 bandwidth. Now there’s a faster and cheaper alternative available. It’s Fast Ethernet or FastE.

Even if you are unaware of Fast Ethernet as a Metro or Carrier bandwidth service, you are no doubt familiar with the term. Fast Ethernet is the name given to 100 Mbps Ethernet. It is one of the standard LAN speeds, along with 10 Mbps Ethernet and 1,000 Mbps Ethernet or Gigabit Ethernet. The abbreviation for Gigabit Ethernet is GigE. The next step up is 10 Gigabit Ethernet or 10 GigE.

Nearly all network devices, including PCs, printers, Ethernet switches, routers and servers have NICs (Network Interface Cards) that support Fast Ethernet. In fact, many smaller business LANs run at the Fast Ethernet speed of 100 Mbps. So, why do our WAN (Wide Area Network) connections run at some lower speed?

One reason is cost. WAN network services have tended to be seen as expensive. Part of that is because these are leased line services that are billed by the month, every month. LAN networks have a capital cost of purchase and installation. After that, most smaller networks need relatively little maintenance.

Another reason why we use lower bandwidths on the WAN than the LAN is usage. Most traffic within a company network stays on the LAN. A lot of it is between PCs & servers and for interoffice file transfers. Traffic that leaves the building is mostly Internet access for both websites and email. Companies with multiple business locations often have dedicated lines between them or use an MPLS network to interconnect 3 or more locations. These links get higher traffic, because they are functioning as in-house LAN connections.

A couple of forces are at work to change this situation. First of all, WAN bandwidth is going up simply because files are larger and video is becoming used more in business. A much larger effect is the move from in-house IT services to hosted services, including cloud services. This effectively moves the bulk of the traffic from LAN to WAN. Line speeds have to increase to accommodate this traffic increase, or access will slow to a crawl. Slow access spells lowered productivity in any business process.

Medium and larger companies outgrew their T1 lines long ago. Their upgrade path has been to T3 service, more popularly known as DS3. With DS3, you get 45 Mbps of bandwidth versus 1.5 Mbps over a T1 line. Your lease costs also goes up from hundreds to thousands of dollars a month.

DS3 has been essential for video streaming, ecommerce, large office Internet access, medical image transmissions and other bandwidth intensive operations. As a digital telecom service it has been readily available with costs that have come down over the years. So why not stick with DS3?

The reason, as usual, involves cost and bandwidth. The competing service is now Fast Ethernet at 100 Mbps vs DS3’s 45 Mbps. That’s over twice the bandwidth, but not twice the cost. In fact, you may well be able to get FastE for the same or less than you are paying for a DS3 connection. Consider that Fast Ethernet more closely mirrors the protocol run on the LAN and that both DS3 and FastE are delivered over fiber optic lines, and it’s hard to see why sticking with DS3 makes good business sense.

The one reason that DS3 may still be the right service for your company is that Carrier Ethernet services have not been deployed everywhere just yet. However, competitive carriers are aggressively building out their metro fiber networks and vying for business customers with lowered bandwidth prices.

Are you a DS3 user interested in getting more money for your bandwidth dollar? Or, do you need new installation of high speed line services and want to make sure you are getting the best deal? If so, check out Fast Ethernet vs DS3 pricing and availability now. Once you have the competitive options, you can choose what type and level of service makes the most sense for your operation.

Broadband Ethernet Connections

When we think of Ethernet, it’s probably in regard to the protocol that runs on our LANs. Broadband? That’s something else entirely. Or is it?

Ethernet has moved from the LAN to the MAN to the WAN. That gives companies the opportunity to extend their networks across town, across the country and even internationally. But what about the Internet? What does Ethernet have to do with the Internet?

Ethernet and the Internet have been closely coupled from the beginning. The Internet is based on IP routing, not legacy telco circuit switching. But the Internet would have gone nowhere without telco technologies such as T1, DS3, and SONET/SDH (OC3, OC12, OC48, etc.) That’s because the telephone companies owned the digital lines and their mature technologies. The sensible and cost effective approach has been to do what is necessary to use these existing services to transport IP packets as well as other voice and data traffic.

That brings us to access. What do you have to connect with the Internet? It’s likely a T1 line, DS3 connection or a fiber optic service based on SONET. Very small businesses may be using DSL, Cable broadband, two-satellite or 3G & 4G cellular wireless. Why not use Ethernet as your last mile connection?

That’s a good question. In fact, it makes more sense now to install a broadband Ethernet connection to the Internet than ever before. The technology is proven and already deployed to most major cities and suburbs. What’s more, it will probably save you money.

The most popular and lowest cost Ethernet broadband services use Ethernet over Copper or EoC technology. This appears to be similar to T1 technology in that it is based on using twisted pair copper wires to bring the service into your building. Chances are that you have the wiring in place already for multi-line telephone service and perhaps a T1 line or two.

Ethernet over Copper offers dedicated Internet access, just like T1, where you have a committed bandwidth level that does not vary and is not shared with other users. The technologies are a bit different in that the EoC interface to your LAN is a simple Ethernet connector. If you are already using a managed T1 router, that may not be important because the interface is already handled by the service provider and you simply connect your edge router to the T1 router.

You’ll notice a difference in bandwidth scalability. T1 lines are designed around a fixed bandwidth of 1.5 Mbps. If you want more, you bond additional T1 lines in 1.5 Mbps increments. This is practical up to around 10 Mbps before it become too expensive for most applications. Ethernet over Copper bandwidth typically starts at 2 Mbps, with 3 Mbps a popular speed for about the same price as a single 1.5 Mbps T1 line. But EoC can easily deliver 5 Mbps, 10 Mbps, 15 Mbps and even 20 Mbps. If you order a port with enough capacity, you can often just call your service provider and have them increase your Ethernet bandwidth at will.

What about higher bandwidths? Above 20 Mbps, perhaps as high as 50 Mbps, you’ll need to switch to a fiber optic connection that offers almost unlimited bandwidth expansion. Once again, Ethernet over Fiber is as scalable as Ethernet over Copper. A Fast Ethernet speed of 100 Mbps is very popular because it is also a standard LAN speed. Larger organizations or more demanding applications will want 1 Gbps or Gigabit Ethernet speed. If you need it, 10 Gbps and even 40 Gbps or more is available.

Broadband Ethernet is not available for residential or home office users. For businesses with their own business addresses, you can get pricing and availability on broadband Ethernet services for whatever bandwidths you are interested in. Costs are very attractive, although Ethernet is a metro service and not readily available in rural areas. For those locations, you’ll need to stick with T1 and bonded T1 solutions.

50 Mbps Ethernet Takes on DS3

DS3 connections have been the traditional upgrade path for companies that have outgrown their T1 lines. But now there’s a newer technology service that gives you more bandwidth at less cost than DS3 and offers an easy upgrade path. That service is 50 Mbps Ethernet.

Let’s see why DS3 has become such a popular bandwidth service and why it will likely be replaced by Carrier Ethernet. A DS3, sometimes called a T3 line, isn’t simply 3x the bandwidth you get with T1. It is 28x the bandwidth. So if you have a 1.5 Mbps T1 line and you upgrade to DS3 service, your new bandwidth is about 45 Mbps. Those numbers are actually rounded so the multiplication isn’t exact. There are also overhead bits that must be assigned to manage a DS3 circuit.

As you might suspect, T1 and DS3 are in the same technology family. The tipoff is that DS3 is also called a T3 line. The “T” designation comes from “T-Carrier,” a set of specifications developed by the phone companies right after WWII to convert analog telephone trunks to digital. The T-Carrier specs are based on a 64 Kbps channel called a DS0 for Digital Signal level 0. A DS1 is comprised of 24 DS0 channels or 1.536 Mbps plus 8 Kbps for synchronization and maintenance for a total of 1.544 Mbps. That’s the T1 line speed.

A T3 line is also composed of DS0 channels at the most basic level. What’s so important about DS0 is that it is exactly the right size to carry one digitized telephone call. These channels can also be used to carry data packets instead of phone conversations. Package 672 DS0 channels together plus synchronization and maintenance bits and you have a DS3 running at 44.736 Mbps. That’s the T3 line speed.

T1 lines were designed to be delivered on 2 pair of ordinary twisted pair copper telephone wiring in a multi-pair binder cable. T3 lines were designed to be delivered on coaxial copper line or microwave transmission. Today, fiber optic cable is generally used to transport DS3 and higher bandwidth services. Bonded copper pair may get the job done over short distances, but is only found in densely populated cities.

The fact is that an upgrade from T1 to DS3 is a major move that requires equipment replacement, perhaps significant construction costs, and a considerable monthly lease price increase. Once you run out of bandwidth on a DS3, you need to move up to the next level of compatible services, OC3, at 155.52 Mbps.

What’s the competition for T1, DS3, OC3 and above? It’s a completely different family of network services called Carrier Ethernet, also known as Metro Ethernet. Carrier Ethernet has more in common with LAN Ethernet than it does with T-Carrier technology. T-Carrier was designed to transport telephone calls. Ethernet was designed to transport data packets. Yes, Ethernet can also be used to carry phone calls and does so exquisitely on converged voice and data networks. An Ethernet connection used to transport telephone traffic may also be called a SIP Trunk.

Now, let’s look at the replacement services for the old T-Carrier system. EoC or Ethernet over Copper is a direct replacement for T1 lines. There are two major benefits to going with EoC. First, the bandwidth is higher. A 2 or 3 Mbps Ethernet over Copper service replaces a 1.5 Mbps T1 line. The cost for both services is roughly the same. When you want to, you can upgrade to 10 or 20 Mbps over copper for more bandwidth.

The replacement for DS3 or T3 lines is 50 Mbps Ethernet. You get a modest increase in bandwidth and you’ll likely see a significant reduction in your monthly line services bill. It is not uncommon to pay half or less for 50 Mbps Ethernet compared with DS3.

You’ll need a fiber optic connection for either service. There is no standard fiber service that runs at the DS3 speed, so it is delivered on a SONET OC3 service using just a third of the available bandwidth. Ethernet is far more scalable. 10 Mbps, 100 Mbps and 1000 Mbps are standard network speeds, but you can get a wide range of increments between these levels. A good strategy is to order the Ethernet bandwidth you need now with an eye to easily upgrading to an incrementally higher speed as needed. The trick is to have an Ethernet port installed that can handle the maximum bandwidth you anticipate needing. If you have a 100 Mbps port, you can get 50 Mbps Ethernet out of that port now and then upgrade in steps to the maximum capacity of 100 Mbps later. Often, this can be done quickly and easily with a simple phone call to your service provider.

Are you anticipating a major WAN bandwidth upgrade, or are you already using DS3 service and either want more bandwidth or lower pricing? If so, get 50 Mbps Ethernet pricing and availability before you make any decisions. It’s a service that will serve you well in the coming years and offer a compelling cost savings as well.

WAN Network Design Options

It’s commonly assumed that the LAN (Local Area Network) and the WAN (Wide Area Network) are completely different animals. You need completely different network design philosophies for each... or do you?

The abyss between WAN and LAN became established by they way they came into being. LAN networks are owned by individuals, businesses and organizations and are based on packet switching. At one time, there were competing topographies such as ring, star and buss. Now it’s all Ethernet on the LAN, with some specialized networks used for such things as disk storage. Most networks are based on twisted pair copper, fiber optic cable, or some combination of the two.

WAN standards grew out of the telephone industry, which has a monopoly on twisted pair telco lines used for both voice and data. Until recently fiber optic networks were also primarily owned by or at least developed to telephone company SONET/SDH standards.

Clearly, there was a technological disconnect between packet switched LAN technology and circuit switched WAN technology. That’s not so much the case anymore, but it is true that you need to do a protocol conversion to connect point to point or to the Internet using telco services such as T1 lines, DS3 bandwidth or OC3 fiber optic connections. Both the circuitry and software needed for WAN network interface are off the shelf items. You simply by a T1 interface card for your router if you want to plug in a T1 line.

What this means is that you can generally mix and match WAN network technologies as long as you have the proper interfaces. T1 line prices have plunged in recent years, making them the entry level WAN option of choice. A T1 line can be used to provide a dedicated broadband connection to the Internet or a direct point to point connection between two business locations. Some companies build customized WAN networks by connecting each branch office back to headquarters using T1 lines to form a star network. The router at headquarters manages traffic between all locations.

What’s new in WAN networking is the rise of Carrier Ethernet and MPLS networks. These are very compatible technologies and can be used together or separately. Carrier Ethernet is a native packet switched technology that avoids LAN/WAN interface issues. You can replace point to point T1 lines with Ethernet line services. Ethernet can also be used to provide a last mile connection to the Internet. Unlike T1, there is an Ethernet LAN service that can be used to connect multiple locations together in a mesh network. Ethernet LAN is a direct replacement for private WAN networks based on T1 lines or higher bandwidth services.

MPLS networks provide a many to many WAN networking solution. MPLS is a protocol that can transport nearly any other protocol in a cloud network. You see T1 lines being used for network access. Ethernet service is also used for last mile network access to the same MPLS networks.

What Carrier Ethernet and MPLS networks offer compared to their telco WAN predecessors is a cost savings and the ability to get out from having to manage the WAN yourself. You can treat Ethernet LAN or MPLS network services as a true cloud that provides the bandwidth, latency and class of service controls you need for converged network operations. Competitive carriers own their core networks completely independent of the telephone companies. In major metropolitan areas, they also provide fiber optic access connections at considerable cost savings over legacy solutions.

What Leased Line Service Providers Offer

Most businesses get their telecommunication services from leased line service providers. That includes telephone, Internet, and point to point line services. You probably have some of these contracts yourself. But do you know about the cost reductions and all of the new services that have become available recently?

The nature of telecommunications services has changed dramatically in recent years. The two biggest changes are cost savings that come from a flurry of new competitive service providers and the introduction of new technologies that offer additional services.

You can still get most of the telecom services that were available a decade or so ago. The most popular line service is T-carrier, especially the T1 line. T1 is a telephone company technology and comes in several flavors. The original use was a digital trunk to carry multiple phone calls between telco switching centers or into a multi-line business phone system. An upgraded version of the T1 telephone line is called T1 PRI or ISDN PRI. It gives you up to 23 outside phone lines plus a data channel for dialing, switching and Caller ID. Nearly every PBX phone system and many key telephone systems can be easily configured to use T1 PRI.

Another use for T1 lines is to provide point to point connectivity between two business locations. A point to point T1 line offers 1.5 Mbps in both directions simultaneously. If you need more bandwidth than this, you can get bonded T1 service that combines multiple T1 lines up to about 10 or 12 Mbps total.

A related service is the T1 access line. This is a last mile connection to a larger network. At one time, the larger network was called Frame Relay. Nowadays, MPLS networks have taken over this role of connecting business locations on a regional, national or international basis. MPLS networks have the advantages of nearly unlimited bandwidth that can transport just about any voice, data or video protocol.

T1 Dedicated Internet Access (DIA) is the choice for broadband Internet access for many smaller businesses. The cost is only a fraction of what it was a decade ago. As a professional grade telecom service, you enjoy a reliability and constant bandwidth not typical of consumer oriented services like DSL and Cable.

The new competition to T1 lines is coming from Carrier Ethernet services, including Metro Ethernet. Like T1, Ethernet is a wireline service. Also like T1, it is delivered on multiple twisted pair copper wiring for lower bandwidth services. That copper wiring is generally already installed for multi-line telephone service. Ethernet offers the same point to point and Internet connections you may be using with T1 lines now. But Ethernet can also give you layer 2 switched network service between several or more locations around town or over a wider area, including overseas offices.

Ethernet is gradually taking over from T1 in metropolitan areas where it is most available. A popular service is 3 Mbps Ethernet for about the same price as a 1.5 Mbps T1 line. For more demanding uses, 10 Mbps Ethernet is becoming a popular standard.

Once you get into the higher bandwidths, 45 Mbps and above, fiber optic cabling takes the place of twisted pair copper. DS3 is the T-carrier upgrade to T1. It is now delivered over SONET fiber optic services at 45 Mbps. The Ethernet equivalent is 50 Mbps Ethernet service, although Fast Ethernet at 100 Mbps is an industry standard and the speed of many local networks. Like copper-based Ethernet services Ethernet over Fiber tends to offer much lower costs per Mbps than equivalent traditional SONET telecom services.

You should also know that both T1 and Ethernet services have an option to get both telephone and Internet over the same line. Integrated T1 is the legacy wireline service. SIP trunking is the IP service that gives you VoIP telephony and broadband Internet access.

Have you been wondering if you are paying too much for the wireline services you’ve just kept renewing over the years? Find out by getting up to date quotes for both Ethernet and T1 or SONET wireline services from dozens of competitive service providers. The range of services and their current costs may astound you.

Switch to Switched Ethernet Service

Are you still living in the world of telecom past? Those are the days when you had one network protocol inside and something completely different outside. Switch to switched Ethernet service and your network has more options and easier interfacing.

What constitutes telecom past? It’s the legacy transport services developed as telephone technologies and later pressed into service to connect data networks through the public switched telephone network. That includes such favorites as Frame Relay, T1, DS3 and SONET/SDH.

What’s so bad about these venerable telecom services? Nothing at all. They are time-tested solutions to business connectivity. All of these services are readily available, perhaps with the exception of Frame Relay which is being rapidly replaced by MPLS networks. They offer high reliability and dedicated bandwidth suitable for business operations. The only real question is whether these are the BEST options available for your connectivity needs.

There’s a newer networking technology being deployed nationwide, indeed worldwide, right now. What it does is simplify the LAN to MAN to WAN connection. Everything is standardized on the Ethernet protocol. Connectivity is seamless, since outside network connections simply plug into your network edge Ethernet switch and become an extension of your LAN.

Contrast this approach to having to install a CSU/DSU interface card into a router to make the networks compatible. Inside your company, everything is packet based. Outside, those packets have to be shuttled into and out of TDM channels that transport them between locations or to and from the Internet.

With an all-Ethernet system, you also gain some service options you didn’t have before. Ethernet line service gives you a point to point connection between two LANs at different locations. Ethernet LAN service creates a multi-point to multipoint network that links 3 or more locations. All of these locations will appear to be on one large bridged network with switched Ethernet service. The engineer at the desk across town is effectively right next door to the marketing manager a couple of states away and the warehouse on the other side of the globe.

Just to add icing to the cake, Ethernet services also tend to be lower in cost per Mbps than equivalent legacy telecom services. It’s not uncommon to get 3 Mbps Ethernet at the same price as 1.5 Mbps T1 service. The distinction gets even larger as you go up in speed and include multiple locations.

Are you missing out by still depending on yesterday’s telecom technology to support today’s business needs? Check pricing and availability of switched Ethernet service to see if you can get better service for less money? There’s a good chance you can.

Fiber Connectivity Options For Business

Fiber optic bandwidth is now well within the reach of most medium and large companies, and even smaller organizations that are bandwidth driven. What’s changed? Lower prices and more options. That’s good news for large bandwidth users. Let’s take a look at what’s available that you may not know about.

Fiber optic bandwidth services tend to fall into two categories. There is the traditional time division multiplexed technology that came out of telephone company research. Competing with those legacy services are the newer IP-centric networks being offered by competitive service providers as well as incumbent telecom carriers.

The fiber optic bandwidth service that is most familiar is called OC-3 or Optical Carrier - level 3. It runs at 155.52 Mbps, commonly referred to as 156 Mbps. What you might not realize is that some lower speed services travel part or all of the way from the service provider to your location on fiber optic cabling. These include T1 and DS3, generally thought of as copper-based telecom services. It’s up to the carrier how they want to transport their bandwidth services, but it’s made easier because both T1 and DS3 are easily multiplexed onto OC-3.

Why is that? It’s because T1, DS3 and OC-3 were all developed by the telephone industry for its own use. The smallest element is called a DS0, which is 64 Kbps of bandwidth organized as 8 data bits x 8 Kbps sampling frequency. A DS0 is exactly the size needed to carry one digitized telephone conversation. Package 24 of these DS0 channels together and you have a T1 line running at 1.5 Mbps. Package 28 T1 lines or 672 DS0 channels together an you have DS3 service at 45 Mbps. Now, package 3 DS3 services together and you have OC-3 at 156 Mbps. The device that does the packaging and unpackaging is called an Add/Drop Multiplexer or ADM.

OC-3 fiber optic service is part of an industry standard known as SONET for Synchronous Optical NETwork. SONET is a US standard. The equivalent international fiber optic standard is called SDH for Synchronous Digital Hierarchy. As you probably know, there are higher speed fiber services in the same OCx family. Commonly available services include OC-12 at 622 Mbps, OC-24 at 1.244 Gbps, OC-48 at 2.488 Gbps, OC-192 at 9.953 Gbps and OC-768 at 39.812 Gbps. That last one is primarily used by service providers themselves.

What’s characterized SONET fiber optic services for decades is high cost and very limited availability. Your best bet for connecting to these high bandwidth services has been at a colocation center, also called a carrier hotel. There’s little to no construction cost to get that level of bandwidth in a colo center, because the carriers have a presence within the building. It’s just a matter of getting a fiber optic cable drop from their equipment cage to yours.

SONET services delivered to your door have also come down in price due to increasing demand from business and heavy competition from another service called Carrier Ethernet. This is Ethernet like you have on your LAN, but extended into the metropolitan and wide area networks. The most familiar name for this service is Metro Ethernet. That’s also where you are most likely to find it - in major metropolitan areas.

Metro Ethernet is a packet or IP-based network service rather than a synchronous TDM service. One difference is that you don’t need special interface circuitry to connect to an Ethernet service. After all, it’s Ethernet and it’s delivered to you on an Ethernet connector. The other difference is the scalability of services. Common speeds are 10 Mbps, 100 Mbps and 1000 Mbps to mirror the standard network speeds. You can also get 10 Gbps now. But you are not limited to these particular bandwidth increments. Most carriers offer a wide variety of speeds from 10 Mbps to 10 Gbps. If you install an Ethernet port at the highest speed you expect to use, you can pay for a smaller bandwidth increment to get started and then upgrade to a higher speed when needed. Often, all that is required is a phone call to your service provider to request an increase in bandwidth.

How about fiber optic pricing? You may still find areas where SONET services are the least expensive, but most of the time it’s Ethernet that has the cost advantage. That’s especially true if you are not running at one of the standard SONET speeds. The cost difference can be half or less for the same bandwidth when you replace SONET with Ethernet.

Do you currently use fiber optic bandwidth services or are you considering them for your business? If so, don’t order anything until you get a side by side price comparison of SONET and Ethernet fiber optic bandwidth. You may be surprised by what’s available at a lower cost than you expected.
