マルチチャネル双方向光通信モジュール
Document Type and Number:
Japanese Patent JP7241175
Kind Code:
B2
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 reception unit are disposed, in which a wavelength of the optical transmission signal for each of the plurality of channels is the same as a wavelength of the optical reception signal for each of the plurality of channels, and the circulator includes a first optical filter which passes a multi-channel optical transmission signal incident to a surface thereof therethrough and reflects a multi-channel optical reception signal incident to the other surface thereof, and a second optical filter which is disposed in parallel with the first optical filter and reflects the multi-channel optical reception signal reflected from the first optical filter to the demultiplexer.
