A parallel wireless optical module with vertical bottom surface emission

Abstract

A parallel wireless optical module emitted from a vertical bottom surface, comprising a driver arranged on a printed board, a limiting amplifier, a lens array with at least one column in number, an MCU, and a substrate that is interconnected with the printed board, and further includes a substrate arranged on the substrate The optical active device used in conjunction with the lens array and communicated with the printed board at the same time; the parallel wireless optical module of the present invention, by flip-chip welding the laser on the printed board of the module, supplemented by the lens for beam shaping, using The high-precision packaging of the micro-assembly platform overcomes the problem of the existing products with MT pigtails, and realizes the cableless communication of the parallel optical module; the present invention adopts the non-contact connection communication, and due to the existence of the lens array, the beam can be shaped into parallel light, After a certain distance of space transmission, it reaches the receiving end. The receiving end adopts a symmetrical optical path structure to effectively converge and receive the beam, which can effectively reduce the wear caused by contact, prolong the service life, and improve reliability.

Description

technical field [0001] The invention belongs to the technical field of wireless optical communication, and in particular relates to a parallel wireless optical module emitted from a vertical bottom surface. Background technique [0002] In the military field, various signal lines are very complex, and fiber optic cables and radio frequency cables are intertwined, and there are many problems. [0003] At present, the products are interconnected through MT pigtails and connectors when in use. Key components include VCSEL arrays or PIN detector arrays, optical coupling units, MT pigtails, and connectors. When using, the optical module is welded on the printed board, and the MT pigtail is inserted into the connector at the same time. The length of the MT pigtail needs to be strictly controlled during the connection process. In addition, the pigtail with the parallel optical module occupies the area of ​​the daughter board and can be used in the compressor box. Space. [0004] ...

AI Technical Summary

Problems solved by technology

[0004] The parallel optical modules currently used have problems such as large volume and low integration

In the future, the platform chassis will develop in the direction of small size, high integration, high speed, and low weight. Therefore, the existing parallel optical modules cannot meet the above requirements and become a big obstacle to the development of aviation, aerospace, electronics and other fields.
