Claim:
1. An optical transceiver, comprising: a coupling assembly; and a condensing assembly; wherein the coupling assembly comprises a first surface and a second surface that are oppositely disposed, wherein an angle is formed between the second surface and the first surface, and wherein multiple first lenses are disposed on the first surface; wherein the condensing assembly comprises a fastener, multiple filters, a reflector, and a light passing region, wherein the fastener comprises a third surface and a fourth surface that are oppositely disposed, the multiple filters and the light passing region are disposed on the third surface, the light passing region is located on a side of the multiple filters, and the reflector is disposed on the fourth surface; wherein the condensing assembly is fastened to the second surface; wherein each of the multiple filters is optically aligned with a respective first lens of the multiple first lenses, wherein each of the multiple filters comprises a pair of light outgoing/incoming surfaces and a pair of side surfaces, wherein the pair of side surfaces are connected between the pair of light outgoing/incoming surfaces, the pair of light outgoing/incoming surfaces are attached to the second surface and the third surface, and the side surfaces of each filter are perpendicular to the first surface; wherein the coupling assembly is configured to receive light of different wavelengths; wherein the condensing assembly and the coupling assembly are configured such that 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; wherein a major axis of each first lens is perpendicular to the first surface; and wherein the angle between the first surface and the second surface is within a range from 6° to 13°.
