What signals are transmitted by optical fiber communication
Oct 13, 2022| What signals are transmitted by optical fiber communication
Optical fiber communication uses optical fiber to transmit optical signals. Optical fiber communication uses optical wave as carrier wave and optical fiber as transmission medium to transmit information from one place to another, which is called optical communication for short.
As far as optical fiber communication technology itself is concerned, it should include the following main parts: optical fiber and cable technology, transmission technology, optical active devices, optical passive devices, and optical network technology.
Function of optical communication network:
1. Signal conversion (sending signal): convert electrical signal into optical signal.
2. Signal multiplexing: gather multiple narrow signals into a wide signal.
3. Signal relay: long-distance transmission and midway relay signal.
4. Signal steering: transfer the transmission direction of the signal.
5. Signal demultiplexing: decompose the multiplexed signal into the original separate signal.
6. Signal conversion (receiving signal): convert optical signal into electrical signal.
