The coaxial portion of the network connects 100-2000 homes (500 is typical) in a tree-and-branch configuration. Radio Frequency Amplifier s are used at intervals to overcome cable attenuation and splitting losses. An optical node converts optical signals to electrical and vice versa. It is a "dumb" device in that it does not Demodulate or otherwise interpret the signals. Fiber Optic cables connect the optical node to a distant Head End or Hub . By using Frequency Division Multiplexing , an HFC network may carry a variety of signal types, including analog TV, digital TV, telephone, and data. Similar to HFC, " Fiber In The Loop " technology is used by telephone Local Exchange Carrier s to provide advanced services to telephone customers over the POTS Local Loop but is not synonymous with Hybrid Fibre Coaxial. |
