Definition Edit

Hybrid fiber-coaxial cable (HFC) is

another term for cable systems that are a combination of fiber (Middle and Second mile) and coaxial cable (last mile).[1]

Overview Edit

It is a second-generation connection technology used by the cable TV industry to bring higher bandwidths to its original coaxial cable networks. The fiber is optical fiber that brings high-speed connections into neighborhoods and makes delivering suitable bandwidth for digital TV, HDTV and cable modem service possible.

HFC networks can be composed of any combination of fiber and coaxial cable. The most common architecture is fiber to the node (FTTN) which involves a fiber cable to each cluster of subscriber homes or neighborhood, where the optical signal is converted for coaxial cable for delivery to individual homes. Less common architectures include fiber to the curb (FTTC) where a single strand typically serves between 8 and 16 homes, and fiber to the home (FTTH) where each individual home has its own fiber termination point.[2]
