OPTICAL TRANSCEIVER AND OPTICAL COMMUNICATIONS PRODUCT

摘要

The present invention discloses an optical transceiver, including a coupling assembly and a condensing assembly. The coupling assembly includes a first surface and a second surface; an angle is formed between the first surface and the second surface; and multiple first lenses are disposed on the first surface. The condensing assembly includes a fastener, multiple filters, a reflector, and a light passing region; the fastener includes a third surface and a fourth surface; the filters and the light passing region are disposed on the third surface; the reflector is disposed on the fourth surface; the condensing assembly is fastened to the second surface; the filters are optically aligned with the first lenses separately; each of the filters includes a pair of light outgoing/incoming surfaces and a pair of side surfaces; the side surfaces of each filter are perpendicular to the first surface; the coupling assembly receives light of different wavelengths; and the light of different wavelengths enters the fastener through the multiple filters and is multiplexed or demultiplexed by the reflector and the filters, and multiplexed or demultiplexed light enters the coupling assembly through the light passing region. The optical transceiver provided in the present invention has advantages of low power consumption and high coupling efficiency. The present invention further provides an optical communications device.
