Hybrid Fiber Optic Cable Communication Standard
Hybrid fiber–coaxial (HFC) is a broadband telecommunications network that combines optical fiber and coaxial cable. It has been commonly employed globally by cable television operators since the early 1990s. In a hybrid fiber–coaxial cable system, television channels are sent from the cable system's distribution facility, the headend, to local communities through optical fiber sub. DescriptionThe fiber optic network extends from the cable operators' master, sometimes to regional headends, and out to a neighborhood's hubsite, and finally to an optical to coaxial cable node which typically se. By using, a HFC network may carry a variety of services, including analog TV, digital TV ( or ),, telephony, and internet traffic. Services on these syste.
