HFC network

HFC network

(Hybrid Fiber-Coax network) A communications network (typically a cable TV network) that uses a combination of optical fibers and coaxial cable. The fiber provides the high-speed backbone, and the coax is used to connect end users to the backbone. Such networks typically use matching DOCSIS cable modems at the head end and the customer premises, providing bidirectional paths and Internet access. See DOCSIS.
