Optical transmitting assembly and optical transceiver module

Abstract

The invention provides an optical transmitting assembly and an optical transceiver module. The optical transmitting assembly comprises a first substrate, and a laser assembly, an incident collimating lens, an optical path adjusting member, an emergent collimating lens and an optical fiber assembly which are sequentially arranged on the first substrate; a light beam emitted by the laser assembly is converted into collimated light through the incident collimating lens; and the optical path adjusting member is arranged between the incident collimating lens and the emergent collimating lens so as to correct the light path deviation of the optical transmitting assembly after the positions of the laser assembly, the emergent collimating lens and the optical fiber assembly are fixed, so that the collimated light output from the optical path adjusting member is coupled into the optical fiber assembly after passing through the emergent collimating lens. In the optical transmitting assembly, after other light components in the light path are mounted, light beam deviation caused by mounting deviation of each light component and raw material processing error can be adjusted by adjusting the light path adjusting piece, so that the coupling efficiency of light in the light path is improved; and further the optical power value of the transmitting end of the optical transmitting assembly meets the requirements of the optical transceiver module.

Description

Technical field

[0001] The present invention relates to the field of optical communication technology, particularly relates to an optical transceiver module and a light emitting assembly. Background technique

[0002] With the development of optical communication technology, the data center of the light module and the single wave 100Gbps module 4 * 100Gbps development of a 4 * 25Gbps module to 100G. Currently 400G module, the laser module is widely used in chip EML, the luminous power is not high, but the optical transceiver module of its optical power value of the transmitting end of the range have strict requirements, which requires high as possible module 400G optical power value which the transmitting end. Inventive content
