Comcast Corp. is using the fiber-to-the-home (FTTH) capabilities of its "Metro Ethernet" platform to power a new residential broadband service with a maximum downstream speed of 305 Mbps and a potential 65 Mbps upstream, not DOCSIS 3.0.
In other words, Comcast is using an overlay approach, running a discrete new fiber from a transceiver node directly to a home, instead of using the cable modem standard and network.
The move suggests Comcast believes demand for the 305 Mbps service will be relatively limited. If high take rates were anticipated, Comcast would simply move to Docsis 3.0. At low penetration, the fiber direct overlay means the entire spectrum plan for each local network can operate without disruption, while still accommodating some growth of the 305 Mbps tier of service.
