Abstract
Provided is a multi-channel, bi-directional optical communication module. The multi-channel, bi-directional optical communication module includes a transmission unit transmitting an optical transmission signal for each of a plurality of channels, a multiplexer multiplexing the transmitted optical transmission signal for each of the plurality of channels to output a multi-channel optical transmission signal, a circulator passing the multi-channel optical transmission signal output from the multiplexer therethrough to transmit the multi-channel optical transmission signal to an optical fiber and reflecting a multi-channel optical reception signal received from the optical fiber, a demultiplexer demultiplexing the multi-channel optical reception signal reflected from the circulator to output an optical reception signal for each of the plurality of channels, a reception unit receiving the output optical reception signal for each of the plurality of channels and converting the received optical reception signal into an electrical signal for each of the plurality of channels, and a body unit in which the transmission unit, the multiplexer, the circulator, the demultiplexer, and the recept…
