ABSTRACT:
A multipoint fiber optical communication system which can carry both voice and data traffic which achieves both full duplex operation and long range with a minimum of apparatus. An active star coupler receives signals from all connected users and provides amplified replicas of all of these received signals to all users. The system may utilize time division or wavelength division multiplex techniques and one embodiment requires only a single optical fiber connecting each user station to the active star coupler.
