What Is Hybrid Fiber Coaxial (HFC)?

TechDogs Avatar

So you've heard of fiber optic and coaxial cable, but what about hybrid Fiber Coaxial (HFC)? HFC is a broadband telecommunications network that combines optical fiber and coaxial cable. It's used to provide television and telephone services to homes and businesses over a wide area. HFC is an all-digital system, with data transmitted as digital rather than analog signals. The digital signal is modulated onto a carrier frequency that travels over the cable. This allows it to be compressed into narrower channels, which helps deliver more services with less bandwidth. Hybrid fiber-coaxial is a new and exciting technology that combines the best of both worlds: fiber optic and coaxial cable. Hybrid fiber-coaxial is used for turning in video, telephony, voice telephony, statistics and different interactive offerings over coaxial and fiber optic cables. Cable operators globally employ hybrid fiber-coaxial. Hybrid fiber-coaxial is also known as hybrid fiber coax. Fiber-optic networks have three main components: the cable operator's master head end, regional head ends, and neighborhood hub sites. The master head end is where the cable operator receives its video signals from satellites. The IP aggregation router at this site aggregates these signals into an optical format for transmission over fiber-optic networks. Regional head ends are connected to the master head ends by fiber-optic cable. They also have IP aggregation routers, but these routers aggregate signals from several different master head end. Neighborhood hub sites are connected to the regional head ends by fiber-optic cable, connecting to fiber-optic nodes serving between 25 and 2,000 homes. In addition to video, master headends may also house telephony equipment that provides telecommunications services to communities. The area hub receives signals from the master headend and adds them to the public, educational, and government access cable television channels, as mandated by franchising authorities.
