CNET GLOSSARY: Terms for the techie
hybrid fiber-coax network
HFC networks combine both optical-fiber and coaxial cable lines. Optical fiber runs from the cable head-end to neighborhoods of 500 to 2,000 subscribers. Coaxial cable then carries signals on their last leg of the journey--from the optical-fiber feeders to each subscriber's home. Hybrid networks provide many of fiber's reliability and bandwidth benefits at a lower cost than a pure fiber network.
