This class provides for all types of communication systems in which optical signals are used to transmit modulated carrier wave information between points. Such communication includes transmitting an intelligence-bearing signal from one point to another in the form of variations in a characteristic of the light wave. The communication may be through free space, fibers or waveguides. These are used to transfer the information with an optical beam, and this beam can be used in various communication schemes to enable the most effective or desired method of moving the information, including optical multiplexing when plural information signals or plural transmitters and receivers are utilized.Subclass 1: FAULT RECOVERY
