Abstract

The invention relates to the field of optical packaging, and provides a packaging structure of an optical receiving module. The packaging structure comprises a tube shell. The tube shell comprises a flat board. One end of the flat board is vertically connected with a connecting board. The connecting board is provided with a circular adapter locating hole. One surface, which is far from the flat board, of the connecting board is provided with an annular welding boss around the adapter locating hole. The flat board is provided with an optical demultiplexing locating recessed trough, supporting bosses and a flexible circuit board locating recessed trough, wherein the optical demultiplexing locating recessed trough, the supporting bosses and the flexible circuit board locating recessed trough are successively arranged in a direction of separating from the connecting board. The sidewall of the optical demultiplexing locating recessed trough is provided with a projected alignment boss. Two supporting bosses are arranged. The packaging structure of the optical receiving module is a multi-component assembly which is machined through a precise machinery. According to the packaging structure and the packaging method, corresponding optical packaging can be finished through one-time multichannel light beam quality analysis and one-time active optical coupling alignment process, thereby greatly simplifying an optical coupling alignment process.

Description

technical field [0001] The invention relates to the field of optical packaging, in particular to a packaging structure and a packaging method of a light receiving module. Background technique [0002] Along with the process of digitization, data processing, storage and transmission have been developed rapidly. The rapid growth of search services with large amounts of data and video services has greatly promoted the development of data centers based on supercomputers and storage. 40G / 100G QSFP+ optical module, as the main product for short-distance data center interconnection applications, has broad market application prospects. The design idea of ​​the data center optical module is to provide higher access density through smaller volume and lower cost, and ultimately increase user access capacity. [0003] Due to the fact that the parallel transceiver optical module can provide greater transmission bandwidth under the premise of smaller space and lower energy consumption, ...
