1. A wavelength diversity optical communication system comprising a plurality of user stations each connected to a central active star coupler by means of separate transmit and receive optical fibers and wherein all of said user stations comprise transmitters and tunable receivers, all of which transmitters operate on the same wavelength, λ

  • 1, said star coupler comprising means to detect transmitted signals from all of said user stations on said transmit optical fibers at wavelength λ

    1, and produce separate light signals at different wavelengths for each of said user stations, means to apply each of said separate light signals to an optical coupler having an output optical fiber for each of said user stations with the intelligence of all said user stations modulated thereon at a different wavelength, said output optical fibers comprising the receive signal fibers of said user stations, and wherein said tunable receiers can be tuned to any desired one of said different wavelengths.
