Full Duplex DOCSIS® 3.1- The Evolution of DOCSIS

Full Duplex DOCSIS® 3.1 is an extension of the DOCSIS 3.1 specification that will significantly increase upstream capacity and enable symmetric multi-Gbps services over existing HFC networks. Full Duplex DOCSIS 3.1 technology builds on the successful completion of the DOCSIS 3.1 specification, which has made deployments of 10 Gbps downstream and 1 Gbps upstream broadband speeds a reality.

In Full Duplex communication, the upstream and downstream traffic concurrently use the same spectrum, doubling the efficiency of spectrum use. With current DOCSIS networks and TDD (Time Division Duplexing), the spectrum is split between the upstream and downstream. Full Duplex communication enables upstream and downstream traffic to use the same spectrum at the same time efficiently.
