2. Radio over fiber - Wikipedia

   en.wikipedia.org/wiki/Radio_over_fiber

   Electrical RF is directly connected to a TV or set-top box. 1550 nm is more popular because it has less losses in the fiber and by using fiber-optic amplifier known as EDFA it is possible to extend the transport distance. 1310 nm loses about 0.35 dB/km of optical signal, 1550 nm loses only 0.25 dB/km. Optical budget between transmitter and ...

3. Hybrid fiber-coaxial - Wikipedia

   en.wikipedia.org/wiki/Hybrid_fiber-coaxial

   RF amplifiers called trunk amplifiers are used at intervals in the trunk to overcome cable attenuation and passive losses of the electrical signals caused by splitting or "tapping" the coaxial cable. Trunk cables also carry AC power which is added to the cable line at usually either 60 or 90 V by a power supply (with a lead acid backup battery ...

4. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...

   Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables.

7. Cable television headend - Wikipedia

   en.wikipedia.org/wiki/Cable_television_headend

   Analog terrestrial TV signals require a processor which is a RF receiver that outputs video and audio. In some cases the processor will include a built-in modulator. Digital terrestrial TV signals require a special digital processor. Digital channels are usually received on an L band QAM stream from a satellite, which uses multiplexing. Using ...
