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.

The nature of communication, the actual data exchanged and any state-dependent behaviors, is defined by these specifications. In digital computing systems, the rules can be expressed by algorithms and data structures. Protocols are to communication what algorithms or programming languages are to computations. [3] [4]
Encoding, sending via a channel, receiving, and decoding are necessary parts of communication. Communication physics is one of the applied branches of physics. It deals with various kinds of communication systems. [1] These can range from basic ideas such as mobile phone communication to quantum communication via quantum entanglement. [2]

Human communication can be defined as any Shared Symbolic Interaction. [6]Shared, because each communication process also requires a system of signification (the Code) as its necessary condition, and if the encoding is not known to all those who are involved in the communication process, there is no understanding and therefore fails the same notification.
