Taking The DOCSIS Upstream To A Gigabit Per Second (2010)

By John T. Chapman, Cisco

Fiber is here. The competition is deploying it. The cable operators are field trialing it. Is this the end for the HFC Plant? Is this the end for DOCSIS? The on-going challenge for the HFC plant has always been its upstream bandwidth. This white paper focuses on the upstream and how technology can drive the upstream direction to a data capacity of 1 Gbps and beyond.

Included is an optimized upstream solution for existing plants consisting of six carriers for North American 5 – 42 MHz HFC plants and a ten carrier solution for European 5 to 65 MHz HFC plants.
