Metro Ethernet for Enterprise Customers
Comparing Metro Ethernet from Cable Companies with Other Options Highest bandwidth services are delivered via connections using fiber end to end. Cable companies typically own their own fiber between head ends and commercial office buildings. Cable companies rarely lease fiber or copper phone wiring from other carriers. This way they know where all their facilities are based.
Metro Ethernet using Hybrid Fiber-Coax (HFC)
Other Metro Ethernet cable options include business services over DOCSIS (BSOD) and based on hybrid fiber-coax (HFC) to support voice, video and data services. HFC uses the headend to a neighborhood node to provide services to individual homes and business is delivered via copper coaxial cable.
Metro Ethernet for High Bandwidth
HFC link conforms to the Cablelabs’ Data Over Cable Service Interface Specifications (DOCSIS) with data divided into multiple channels. DOCSIS 2.0 can support speeds up to 40Mbps downstream and 30Mbps upstream using two single channels in both directions. DOCSIS 3.0 can support speeds up to 160Mbps downstream/120Mbps upstream using at least four single channels in each direction. It is important to note not all cable operators offer the full throughput that BSOD can support.
Options When Fiber is not Available
Where Fiber is not available to a building coax is a better choice to support Metro Ethernet services compared to phone company copper wiring because it can more easily support high bandwidth. Unlike Ethernet over Copper phone wiring, BSOD Metro Ethernet services essentially have no distance limitations. BSOD rates can be maintained over distances of up to 100 miles between the headend and the customer.
Limitations to Traditional Copper Wiring
Traditional copper phone wiring can support the highest data rates lonely by using multiple copper pairs – in some cases up to eight – and the appropriate pairs may not always be available.
If your enterprise is considering metro Ethernet as an economical option for high bandwidth there are many variables to consider. To make sure you have a smooth Transition from legacy Ethernet contact your Metro Ethernet Expert Today!
