Information:
Hybrid Fiber Coax (HFC) architecture combines the advantage of the high bandwidth of fiber
optic with the shared nature of coaxial cable technology.
The Hybrid Fiber Coax Network is an emerging cable architecture for providing residential
video, voice telephony, data, and other interactive services through subscribers' homes over
existing infrastructure. Hybrid fiber coax technology invloves the transmission of multi-
media signals over long distances via fiber optic cable, to prevent signal loss and
degradation. The fiber reaches a point known as the Optic Node at which point it is
re-modulated into an electrical signal and broadcast over a coax Trunk and Branch topology
that covers about 125 - 2000 homes. The Network Headend serves as a central location for
services offered over the HFC Network. Analog and Digital services like PSTN (Public
Switched Telephone Network), ATM Network, and Cable TV Programming are possible for the HFC
Network. The Headend Network also serves as the interface of the access network to external
wide area networks, like the telephone network and the Internet.
