For optical transmission of satellite signals and CATV channels over long distances, a transmitter, several receivers and a wide range of accessories of distributors, cables and attenuators are used.
The RF signals are converted into optical signals. These are distributed from the output of the transmitter via distributors and optical cables to optical receivers without noise or distortion. The receivers convert the optical signals back into satellite signals and the CATV channels. Devices are available as receivers for connection to SAT receivers (Quad) , single-cable receivers (SCR/CSS) or multi-switches (Quattro).
