What is HFC | Hybrid Fiber Coax network basics
This page explains HFC basics.The HFC stands for Hybrid Fiber Coax network.
A transmission system or cable construction which combines both the fiber optic transmission as well as copper coaxial transmission is referred as HFC.
The depicts typical HFC network. As shown fiber cable runs from distribution center till the end of the area of street where users are located. From this location, connections to individual users are given using coaxial cables.
In HFC network, area in the range of hundred kilometers is served from the central or main office. As cascaded amplifiers are not needed here, signal quality is not degraded and retained well.
Signal to be distributed using fiber cable is multiplexed using subcarrier multiplexing before connecting onto the cable interfaced with user premises.
