Optical Communication Systems
Optical Communication Systems refers to the devices used for communicating at a distance using light to carry information. A transmitter, which encodes a message into an optical signal, is used to carry the encoded message to the receiver.
Optical fiber is an example of said system. The transmitters are generally light-emitting diodes (LEDs) or lasers diodes. It transmits information by sending pulses of infrared light. The signal encoding is done by intensity modulation.
Optical Communication Systems such as Optical Fiber are most commonly used by telecommunications companies for internet connections, cable television and telephone signals transmitting.
