Full Duplex DOCSIS Technology over HFC Networks (2016)

By Belal Hamzeh, CableLabs, Inc.

DOCSIS 3.1 technology provides a significant increase in network capacity supporting 10 Gbps downstream capacity and 1 Gbps upstream capacity. To support Gbps symmetric services over the HFC plant, increasing the upstream capacity is required. Full Duplex Communication using DOCSIS 3.1 technology provides the ability to increase the upstream capacity without sacrificing downstream capacity. In this paper, we provide an overview of how full duplex communications using DOCSIS technology can be implemented over the HFC network and the potential capacity gains it can deliver.
