A transmitter optical sub-assembly, includes a prism body, a first lens, and a plug-in. The prism body includes a light inlet end and a light outlet end, the first lens is disposed between the light outlet end and the plug-in, and the plug-in includes a contact end. The contact end is located on a surface that is of the plug-in and that is away from the first lens, a center of the contact end is located on a focus on an optical path of the first lens, and the contact end is arc-shaped for a purpose of a gapless interconnection with an optical fiber, to reduce end face reflection of the contact end. An optical transceiver assembly includes the transmitter optical sub-assembly, and has comparatively small reflection and a comparatively small return loss of an optical fiber end face.

Transmitter optical sub-assembly and optical transceiver assembly

An optical transceiver, including a coupling assembly and a condensing assembly, is provided. The coupling assembly includes a first surface and a 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 condensing assembly is fastened to the second surface; the filters are optically aligned with the first lenses separately; 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.
