Abstract
A full duplex optical signal transmission system comprising a pair of transceivers interconnected by means of a single fiber optic cable is provided with an optical receiver for detecting transmitted and received optical signals and a delay and compensation circuit used in conjunction with a differential amplifier coupled to the optical signal receiver for separating the transmitted optical signal from the received optical signal for providing an output from the transceiver comprising a signal corresponding to the received optical signal.
