A multiplex optical transmission system for simultaneously transmitting and receiving a plurality of signals while minimizing external interference. The system includes a plurality of subgroup mixers wherein video signals, digital data signals, and audio signals are supplied to the respective subgroup mixers for being blocked into respective frequency ranges. The output of the subgroup mixers are, in turn, fed to a master mixer that produces a composite electrical signal therefrom. An optical transmitter is connected to the master mixer for converting the composite signal into an optical signal and transmitting the optical signal over a fiber optic cable. An optical receiver is connected to the other end of the fiber optic cable for receiving the optical signal and converting such back into a composite electrical signal. A de-multiplexer is coupled to the output of the optical receiver for separating the composite signal back into a composite video, data, and audio signals. A programmable optical patch board is interposed in the fiber optic cables for selectively connecting the optical signals to various receivers and transmitters.
