10 Gigabit Bandwidth Options

Metropolitan and wide area network speeds are on the rise. Undersea cables are being upgraded from 10 to 40 and soon 100 Gbps bandwidths, with terrestrial fiber runs moving to 100 Gbps now. Likewise, major corporations, healthcare providers and video content producers are starting to feel the squeeze of too small network connections. Fortunately, there are more options and better pricing available today than ever before.

There are several practical solutions to increasing your MAN or WAN bandwidth above the Gigabit per second level and up to 10 Gbps. Let’s see what we can do with SONET, Ethernet, Wavelength and Dark Fiber.

SONET is the telecom fiber optic standard invented by Bell Labs for the telephone industry. It was originally deployed to transport thousands upon thousands of simultaneous telephone calls between switching centers. SONET has evolved to carry data as well as digitized phone calls. As it turns out, voice traffic is in the minority now.

SONET stands for Synchronous Optical NETwork. That describes how it is designed. This is a tightly synchronized time division multiplexed system intended for switched circuit implementation. There are specific service levels associated with SONET levels. These are designed as OC or Optical Carrier levels. The lowest generally available is OC-3 at 155 Mbps, followed by OC-12 at 622 Mbps.

The next level OC-24 takes you to the Gigabit level at 1.24 Gbps. OC-24 isn’t as commonly deployed as the next level, OC-48 at 2.5 Gbps. OC-48 is becoming the new high bandwidth standard for organizations that need high speed private lines or dedicated Internet connections. OC-192 is the 10 Gigabit service level, running at a line rate of 9.95 Gbps. From there you jump up to OC-768 at 40 Gbps. You’ll recognize that as a backbone network bandwidth for fiber optic carriers. OC-768 isn’t generally required at the corporate level just yet.

Notice that there are fairly wide gaps in the service levels between SONET OC levels. If you need 2 Gbps, OC-48 service at 2.5 Gbps makes sense. However, if you need 3 Gbps, you have to go all the way up to OC-192 at 10 Gbps. In some cases, you can find fractional OC-48 service at a better price. This is simply OC-48 that is throttled to provide only the 3 Gbps or other bandwidth you need. There might not be much cost savings, since OC-48 is a standard service level and fractional SONET services are a special order, if available.

Carrier Ethernet is a far more scalable service than SONET. It does have industry standard service levels, such as 100 Mbps Fast Ethernet, 1 Gbps Gigabit Ethernet and 10 Gbps 10 GigE. Most service providers will allow you to scale your service in small increments up to the maximum capacity of the installed port. With a 10 GigE Port, you can easily get 3 Gbps, 9 Gbps or bandwidths in-between. Since Ethernet networks were designed with this scalability in mind from the beginning, service level changes are fairly automated and can be made in a matter of days, if not hours, with no equipment changes needed.

Wavelength services are offered for high performance latency sensitive applications. Dense Wavelength Division Multiplexing (DWDM) splits the fiber optic laser beam into dozens of individual wavelengths or colors that act as independent private lines. There is no interconnection between wavelengths. A wavelength is dedicated to your needs and carries your traffic exclusively. Typical speeds available are 1 GigE, 2.5 Gbps, 10 Gbps, 10 GigE and 40 Gbps. Note that both SONET and Ethernet protocols are available over individual wavelengths.

Dark Fiber gives you the ultimate in flexibility. It is simply a glass strand between two of your locations. You can run any protocol you like at any speed you want over as many wavelengths as you care to deploy. Bandwidth is nearly unlimited, but the catch is that you have to buy, install and maintain the transmission equipment that feeds the fiber.

Have your requirements reached the point where 10 Gigabit bandwidth services are a reasonable consideration. The good news is that there are multiple carriers eager to bid for your business between 1 Gbps and 10 Gbps or beyond. Get competitive quotes for Gigabit and 10 Gigabit level fiber optic services now. You may be surprised how affordable these high bandwidth services have become.

SONET Rings To Support Ethernet

The hot bandwidth service these days is Carrier Ethernet. Everybody wants it once they see the cost advantage over the WAN connection they have now. The big question is can they get it?

In most cases, the answer is yes for a couple of reasons. First, new competitive carriers are rapidly building out their fiber optic core networks based on IP from the start. These networks are tailor made for Carrier Ethernet services. It’s relatively easy to get a point to point Ethernet connection between two distant business locations and use it to link their respective LANs. The result is one larger bridged LAN that enables all employees to be on essentially the same corporate network.

The other reason that Ethernet WAN services are so readily available is that established SONET fiber optic networks are being pressed into service to deliver Ethernet to the customer. This is known as Ethernet over SONET or EoS. The core of the network is still SONET, but operations at that level are invisible to you. As far as you are concerned, your connection is Ethernet all the way.

There’s no reason that SONET can’t transport Ethernet, ATM or other protocols. It was designed as a transport technology and has been adapted over the years to carry whatever traffic required hauling. The origins of SONET, like T-Carrier, are with the telephone industry. The name is an acronym for Synchronous Optical NETwork. Note the term synchronous. That tells you SONET is set up to be a highly synchronized network. The designed is based on multiplexing thousands of small channels called DS0s that each hold one telephone call. These DS0 building blocks can be combined to create T1 and T3 lines or SONET services such as OC-3, OC-12 and OC-48.

The beauty of synchronization for circuit switched architectures based on time division multiplexing is that everything is orchestrated so tightly and you can easily multiplex and demultiplex channels and higher level services. The device that does this is called an ADM or Add/Drop Multiplexer. An ADM can drop off a T1 line, DS3, OC3 or other service at your door from a much higher speed fiber line that carries traffic for many customers.

How does Ethernet squeeze into those tiny telephone channels? It takes some doing, considering that each DS0 carries exactly 64 Kbps. That’s about the speed of an old dial-up modem. What the industry has done is replace the telephone oriented channels with large concatenated frames and various mapping techniques to more efficiently carry Ethernet packets. SONET networks can now readily carry Ethernet services from standard 10 Mbps Ethernet to 100 Mbps Fast Ethernet, 1000 Mbps Gigabit Ethernet (GigE), and 10 Gigabit Ethernet (10GigE).

A feature of most SONET networks that makes them highly reliable is their twin ring design. Two separate fiber strands are used simultaneously. Each carries the same traffic, but in opposite directions. If a fault occurs in the working ring, the network switches over to the protection ring within 50 mSec. This self-healing property works best when the two rings are widely separated so that a single backhoe cut or equipment fault doesn’t take out both rings at once.

Ethernet over SONET and native IP networks are making Carrier Ethernet services of all speeds readily available for businesses looking to upgrade their bandwidth connections at reasonable costs.

Ethernet Internet Service Access For Business

Internet access has become key to doing business, both on the Web and for bricks and mortar operations. The Internet has become ubiquitous in connecting to customers, suppliers, remote workers and even between company locations. So, is business Internet the same as what consumers use or are there differences?

There are various characteristics of Internet service access you can choose, including dedicated or shared, symmetrical or asymmetrical, wired or wireless, copper or fiber, bandwidth level and cost. One of the newest and most cost effective services that meets the needs of many business locations is Ethernet Internet service. Can it be what you are looking for? Why not get an instant online price quote and compare with what you have now?



These Ethernet Internet service access quotes are for business locations only, not residences. At the low end of the price spectrum are business Cable broadband connections which are shared bandwidth and asymmetrical. They give you a high maximum download speed, but that speed varies all over the place since the bandwidth is shared among many users. Download speeds are 10x or so upload speeds, specifically intended for Web surfing, email, and watching online video.

Ethernet over Copper and Ethernet over Fiber Internet Service works more like traditional telecom lines. The bandwidth is symmetrical so that upload and download speeds are the same. You also get the bandwidth you order since it is dedicated to your use only and doesn’t depend on what other users are doing.

Ethernet over Copper uses the same twisted pair copper telco wiring that you use now for multi-line telephone and T1 lines. That’s makes construction costs negligible in many cases. Line speeds are available from 1 Mbps on up to 100 Mbps or more, depending on how far you are from the central office where your wiring connects. Up to 8 copper pair may be used to deliver the higher bandwidths.

Ethernet over Fiber requires a fiber optic line, but it delivers much higher bandwidths. With EoF, you can easily get Fast Ethernet at 100 Mbps and Gigabit Ethernet at 1000 Mbps. In some cases 10GigE is also available for large enterprise applications.

Can you get twice the bandwidth for the same money as you pay now by switching to Ethernet Internet Service for business? Check the speeds, prices and availability and compare with your current Internet service.

Insatiable Demand For Ethernet Bandwidth

Not so long ago, 10 Gbps was considered an enormous amount of bandwidth. So enormous that it only made sense for carrier backbone networks. Not anymore. Now enterprises are gobbling up that much WAN bandwidth and looking for more.

Who could possibly require 10 Gbps, short of an Internet service provider or MPLS network operator? Financial services, streaming entertainment media and medical campus connectivity are three applications on the cutting edge of high bandwidth demand, as reported in Carrier Ethernet News. How much more would they like? Some are licking their chops at 40 Gbps and even 100 Gbps.

How can a carrier keep up? Make no mistake about it, competitive service providers are in a scramble to make sure they have enough capacity to supply this burgeoning demand for higher and higher bandwidths. The once impressive T1 line is now considered a small business service. DS3 still hangs on for medium size business applications. OCx SONET, recently the darling of large enterprises, is starting to see its flame flicker on the way out. What’s happening is more than a simple escalation of bandwidth requirements. It’s a wholesale move from legacy telecom services to Ethernet connectivity.

Why Ethernet? There are a couple of strong forces at work nudging WAN bandwidth suppliers in the direction of offering Ethernet rather than some other type of connection. The first is a realization that analog telephony, the impetus behind the buildout of the massive PSTN (Public Switched Telephone Network), is now the smallest piece of the bandwidth pie. It’s the PSTN standards of T-Carrier & SONET that created the digital WAN services that have been pressed into service for data packet transport. The big piece of the pie is digital data and biggest piece of that pie is video.

No only are data packets the predominant information that needs to be moved from one place to another, but the networks generating those data packets are nearly all based on Ethernet. Why switch to something else just to get from one Ethernet network to another?

That’s what many carriers have concluded. Their new state of the art national and international networks are all designed to transport Ethernet packets. Those packets may represent voice from enterprise VoIP telephone systems, video conferencing or video streaming, medical images, or data file transfers. Interfacing and management of Ethernet bandwidth is more compatible with local area networks running Ethernet, but that’s not all. In most cases, Ethernet bandwidth is cheaper on a Mbps or Gbps basis than any other service.

How much cheaper? That depends on what facilities are available in your location more than anything. If you have competitive Ethernet services available, it’s not uncommon to get twice the bandwidth for the same money or keep the bandwidth you have now and get a big cost savings.

Can you ignore the Ethernet revolution? Only at the peril of your budget! It’s quick and easy to see what Ethernet bandwidth services are available for your business location. Why not take just a minute and put in a request for services and pricing now?

Fiber Optic ISP

Not so long ago, Internet service came through the telephone as a collection of audible beeps and squeaks. That evolved into dedicated landline and wireless broadband. The next step has already been taken by the largest companies. Now, medium size businesses are also looking for a fiber optic Internet service provider.

Fiber optic Internet service for residential users is the domain of Verizon’s FiOS. Google will soon enter the market on a test basis with a new benchmark of performance: 1 Gbps. But business broadband connections have moved past the Gbps upper limit, with 10 Gbps service becoming more common for major organizations. The technology is proven. The question is how much bandwidth do you need and where do you need it?

The key to fiber optic levels of telecom service is the “lit” building. That’s a location where fiber optic cable has been pulled into the facility and connected to terminal equipment. Once the fiber is lit by a service provider, the building is considered to be “on net” and able to select from a wide variety of service options. This facility can also be a jumping off point to provide fiber optic service to other nearby buildings. The most expensive and time consuming aspect of fiber optic service is the initial fiber construction.

What types of fiber optic bandwidth services are available? They typically fall into two categories. The first is traditional SONET / SDH telecom services. These are the original telco standards for voice and data over fiber optic strands. The most basic service is OC-3 or Optical Carrier, level 3. This is a 155 Mbps bandwidth service based on the same TDM or Time Division Multiplexing technology as copper based T1 and T3 lines. In fact, DS3 bandwidth at 45 Mbps is most often delivered as part of an OC-3 signal that can transport 3 of these DS3 services.

The SONET standard fiber optic services include OC-12 at 622 Mbps, OC-48 at 2.5 Gbps, OC-192 at 10 Gbps and OC-768 at 40 Gbps. This highest levels are most often used by carriers, themselves, as their backbone networks.

The other category of fiber optic service is Carrier Ethernet or Metro Ethernet. Ethernet services are standardized at the same levels seen in LAN networks. These are 10 Mbps standard Ethernet, 100 Mbps Fast Ethernet, 1000 Mbps GigE, and 10 Gbps or 10 GigE service. Intermediate service levels are generally available, as Ethernet is readily scalable.

How do you decide between SONET and Ethernet Internet connections? Both are reliable, proven technologies that can deliver the bandwidth you desire. What often differs is availability and price. The best approach is to get a complete selection of fiber optic service quotes from a telecom broker and compare pricing on the services available for your business location. You may be surprised at how affordable the higher bandwidths have become.

Diverse Connections For Data Centers

When you are running a data center or collocating your servers in a colo data center, the reliability of the data connection is critical to the availability of your services. Any one single piece of equipment and any one data line can fail. To ensure that no link failure will take you down, you need more than just several separate network connections. You need multiple diverse data connections.

The difference between multiple connections and multiple diverse connections is in where those connections go to. If you simply have 3 Fast Ethernet or OC3 links to a single service provider, you’ve only gained a small amount of protection. Especially within the colo facility, it’s relatively unlikely that only the network cable for a particular feed or the interface circuits on both ends will fail. It’s more likely that something more catastrophic will take down the entire connection with that provider.

If you are in your own facility, you’ve got the same concern only multiplied. A service provider within a colocation facility probably has multiple incoming connections. The line that comes to your building is likely a single connection that runs for miles underground or overhead. There’s lots of opportunity for a natural disaster or someone doing construction to break that line or multi-pair bundle.

So how do you protect your interests for services that absolutely can’t afford to go down even for a few hours? In addition to the usual server redundancies, you need to get multiple data line services from different providers coming in on different routes. It does you no good to contract with three separate vendors only to find that they are all bundled in the same copper or fiber optic cable. In fact, you don’t even want them sharing the same trench or poles, if at all possible. The ideal situation is to be fed by unrelated suppliers coming from different geographical directions. The only place they’ll be in proximity is within your facility.

This requirement is common for large colocation data centers that host hundreds or thousands of companies. Within the colo center, you can typically order service from several carriers who will individually provide lines to your racks. For your own facilities, you’ll need to do your homework to ensure that your are, indeed, getting diverse data connections.

Sounds like a lot of work to find and evaluate multiple providers who will serve your business location, doesn’t it? Fortunately, there’s help available from a telecommunications service broker who routinely works with dozens of service providers offering everything from point of sale wireless data connections, through the popular T1 lines and DS3 connections, on up to OC3 and above SONET fiber optic services and Ethernet at the GigE and 10GigE levels. You can save yourself a lot of grief and a lot of time by letting the broker work with the available carriers to meet your requirements. What’s that extra service going to cost you? Nothing. Nothing, at all.
