摘要: Signal light output from a signal generator of transmitter is synchronous polarization scrambled in scrambler accordance with modulation repetition frequency fo which approximately coincides bit rate, and then transmitted to an optical receiver via transmission system. The photoelectric converts amplifies the received sends this band reject filter. filter intercepts only noise component components vicinity thereof are produced by scrambling, while other sent equalizing decision circuit. As result, there provided communication system reception apparatus wherein at time transmitting reduced so that deterioration characteristics prevented.
