OPTICAL TRANSMISSION APPARATUS AND OPTICAL RECEIVING APPARATUS WITH REDUCED DEPENDENCE ON ELECTRIC DEVICE

摘要

PURPOSE: An optical transmission apparatus and an optical receiving apparatus with reduced dependence on an electric device are provided to reduce dependence on an electric device of an optical receiving apparatus by inserting an optical demultiplexer to a front end of the optical receiving apparatus. CONSTITUTION: An optical transmitter(110) generates and transmits an optical signal. An optical fiber(120) transmits the optical signal generated from the optical transmitter(110). An optical amplifier(130) amplifies the optical signal transmitted through the optical fiber(120). An optical demultiplexer(140) demultiplexes the optical signal amplified by the optical amplifier(130). An optical receiver(150) receives the optical signal demultiplexed by the optical demultiplexer(140), converts it into an electric signal and detects the electric signal.
