SINGLE-FIBER COUPLED MULTI-WAVELENGTH OPTICAL TRANSCEIVER MODULE

摘要

The present patent application discloses a single-fiber coupled multi-wavelength optical transceiver, comprising a fiber ferrule, a circulator subassembly, a multiplexer/demultiplexer subassembly, an optical transmitting subassembly and an optical receiving subassembly. The circulator subassembly comprises three ports. The optical transceiver comprises an optical receiving unit and an optical transmitting unit. The light beams of the optical receiving unit incidents from the fiber ferrule to the first port of the circulator, then output to multiplexer/demultiplexer through the second port of the circulator subassembly. The light beams is then split by the multiplexer/de-multiplexer and received by the receiver optical subassembly. The light beams of the transmitting unit input to the multiplexer/de-multiplexer from the transmitter optical subassembly. After combined by the multiplexer/de-multiplexer, the light beams incident into the third port of the circulator subassembly. Then the light beams output from the first port of the circulator subassembly and input to the fiber ferrule. The present application avoids the fiber coiling risk of existing optical transceiver and meets the requirement of miniaturization.
