An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
The word communication has its root in the Latin verb communicare, which means ' to share ' or ' to make common '. [1] Communication is usually understood as the transmission of information: [2] a message is conveyed from a sender to a receiver using some medium, such as sound, written signs, bodily movements, or electricity.

Communication physics aims to study and explain how a communication system works. This can be applied in a hard science way via Computer Communication or in the way of how people communicate. [1] An example of communication physics is how computers can transmit and receive data through networks.
There exist many types and uses of channel models specific to the field of communication. In particular, separate models are formulated to describe each layer of a communication system. A channel can be modeled physically by trying to calculate the physical processes which modify the transmitted signal.
A physical medium in data communications is the transmission path over which a signal propagates. Many different types of transmission media are used as communications channel. In many cases, communication is in the form of electromagnetic waves.
In telecommunications, a transmission system is a system that transmits a signal from one place to another. The signal can be an electrical, optical or radio signal.The goal of a transmission system is to transmit data accurately and efficiently from point A to point B over a distance, using a variety of technologies such as copper cable and fiber-optic cables, satellite links, and wireless ...
