Disruptive Metro Ethernet over Fiber Pricing Arrives

Ethernet over Fiber (EoF) has been gaining popularity with large organizations as a replacement for more expensive SONET fiber optic services. For smaller and medium size companies, the mere mention of the term “fiber” suggests pricing that is way over budget. Today that’s all changed. The era of affordable fiber optic bandwidth has arrived.

What’s responsible for prices per Mbps or Gbps that can be half of what you’d expect to pay or less? It’s a source you would never expect... Cable TV. Cable? Isn’t that for consumers?

Yes it is. But behind the scenes there’s another Cable network you probably didn’t know even existed. It’s a professional fiber optic core network that’s the equal of any carrier and with a service footprint larger than most.

When we think of Cable TV, we think of the coaxial wire that plugs into a set top box or cable modem. At one time, all cable networks were constructed almost completely of copper coax strung on poles around town and trenched through the back yard. That was the era of Analog Cable. What’s happened over the years is that this network architecture has evolved into a combination of fiber optic and copper called HFC or Hybrid Fiber Coax that supports the newer digital services.

HFC uses fiber optics for the long runs that bring service into a business or residential neighborhood. It also runs between cities for large Cable MSOs (Multi-System Operators) like Comcast. Most of the traffic on that fiber is television video, but there is so much bandwidth available that it also easily transports data from 10 Mbps on up to 10 Gbps.

Comcast has recognized that their nationwide network runs past businesses as well as consumers. Many smaller businesses take advantage of the excellent pricing on Cable broadband brought in on coaxial cable to a cable modem. It’s quite possible to get 50 Mbps or even 100 Mbps asymmetrical shared bandwidth for the same pice as a T1 line.

Asymmetrical means that the download speed is much higher than the upload speed. Typically that’s a 10x bandwidth difference. This is common for Internet access, but different from business telecom services that are generally symmetrical or the same speed for both upload and download.

Comcast’s Ethernet over Fiber bandwidth services are symmetrical and intended for Enterprise applications. There are 4 services you’ll be interested in. They are Ethernet Dedicated Internet (EDI), Ethernet Private Line (EPL), Ethernet Virtual Private Line (EVPL) and Ethernet Data Network / Meshed Network (EDN). All of these services are available in bandwidths from 10 Mbps to 10 Gbps.

Ethernet Dedicated Internet gives you the Internet access you need to support large employee user bases and connectivity with customers worldwide. Dedicated means that the bandwidth you order is always available for your use. That differs from shared bandwidth that is common for consumer services and wireline cable modems.

Ethernet Private Line (EPL) is a point to point connection service. You may be using T1 lines for linking two business locations now and wishing you had more bandwidth. EPL using Ethernet over Fiber can give you the higher bandwidth you need immediately with nearly unlimited growth potential for the future.

Ethernet Virtual Private Line (EVPL) is another Ethernet private line service. It is similar to EPL, but allows multiple Ethernet services on the same physical line and UNI (User Network Interface). These come in on EVCs or Ethernet Virtual Connections. What the virtualization does is let you run Ethernet Private Lines out to each of several business locations without having to pay for multiple fiber or wireline terminations at headquarters.

Ethernet Data Network / Meshed Network (EDN) lets you establish a large Metro or Wide Area Network to interconnect LANs for your branch offices or other business locations. As a meshed network, you have any to any connectivity. This is similar to might set up with a Frame Relay or MPLS network.

Are you ready for fiber optic bandwidths but not fiber optic service prices? Depending on locations, you may be in position to benefit from the enormous cost advantage of HFC based Ethernet over Fiber bandwidth services. Get pricing and availability before you sign up for anything else.

HFC Broadband For Business

Many small businesses don’t fall into the category of “residential” users but don’t need or can’t afford the cost of traditional business telecom services, such as T1 lines or Ethernet over Copper. One possible solution is HFC or Hybrid Fiber Coax broadband services.

Hybrid what? You may have heard of this as Cable broadband for business. A lot of home based businesses successfully use Cable broadband to manage their websites, access information on the Web and send and receive email. But try to order residential service for a business location and you’ll get turned down flat. That’s because residential broadband is priced for single homes and apartments with few people accessing the service and probably no-one online most of the day. Knowing that, some business owners incorrectly assume that you can’t get Cable run into a business. But you can.

So, what’s available and why the funny name? HFC or Hybrid Fiber Coax refers to the technology used to deploy high speed Internet access, telephone service, and Cable television. You know that Cable TV and Cable broadband are called that because of the coaxial cable that provides the connection to the network. When Cable systems were first deployed, they were constructed from various size coaxial cables. What’s happened in recent years is that the long connection from the Cable office or the “head end” where the signals are picked up and run for miles to various neighborhoods has been replaced by fiber optic cable. The last few hundred feet or so are still copper coaxial cable, also called coax. The result is a system that is a hybrid of fiber optic cable and coax cable known as Hybrid Fiber Coax or HFC.

Why go with a hybrid arrangement rather than just make it fiber optics all the way? It’s mostly a matter of cost. While fiber has a far larger capacity, there is a lot of coax already in the ground. The interface connection at the premises, either a Cable modem or set top box, is much less expensive than the termination equipment needed for fiber. Don’t count that coax down and out yet, either. With digital signals, there is more than enough bandwidth for triple-play services to small and medium businesses as well as consumers.

With an already built-out infrastructure and a high number of users to cover costs, you might expect that HFC services are lower in cost than most telecom services available for the SMB. You’re right, they are. But you need to know the performance tradeoffs to make a smart buying decision.

One excellent use for HFC is broadband Internet access when employee use is primarily Web browsing and email. That includes information research, making purchases, doing simple banking, messaging customers, providing a WiFi hotspot and so on. If most of what you do is similar to the way you use a computer at home, HFC should work just fine. You select a bandwidth tier that offers enough speed to work efficiently and still saves you money over other options. Typical bandwidth for smaller businesses goes up to 15 Mbps download and 2 Mbps upload, although some Cable companies are offering speeds as high as 50 or even 100 Mbps.

You’ll likely be able to get a high speed Internet solution that meets your needs with a lot more bandwidth than a T1 line offers and for a lot less money. But beware. T1 lines are dedicated bandwidth that stays a rock solid 1.5 Mbps all the time. Cable bandwidth is shared among all the users on the Cable and can vary all over the place. That’s one way they hold the cost down. If you are running high traffic ecommerce servers or using business processes that expect constant bandwidth, you might find the speed variations not worth the cost savings. Otherwise, you might be quite happy with both the performance and reliability of HFC broadband.

Another service that Cable companies have gotten into is business telephone, essentially VoIP. One big difference between this service and simply running a third party VoIP service over your broadband connection is that the Cable version never transits the Internet. The voice packets travel over the cable network and are then terminated to the public telephone network by the Cable company or a telephone service provider. By doing it this way, the HFC operator has more control of things like latency, packet loss and network congestion to ensure decent voice quality.

Finally, HFC offers Cable TV channels. After all, that’s why the network was built in the first place. Businesses with waiting rooms, like automotive service centers and doctor’s offices, can put business Cable TV service to good use.

Have you been frustrated by your current choices in network services? Why not compare prices, availability and service features of HFC, T1 and Ethernet so you can make the best buying decision? You may be surprised by the range of options available.
