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.
A system for communications where a carrier signal is impressed on power line wiring. carrier wave A radio wave that can be modulated (changed systematically) to carry information to a receiver. Category 3 cable A performance standard for unshielded twisted pair cables for analog voice and low speed data circuits within a building. Category 5e ...
A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment ...
The Bluetooth system, for example, uses phase-shift keying to exchange information between various devices. [44] [45] In addition, there are combinations of phase-shift keying and amplitude-shift keying which is called (in the jargon of the field) quadrature amplitude modulation (QAM) that are used in high-capacity digital radio communication ...
