The pure electricity portion comprises a base plate installed on the cushion block, and an electric chip is installed on the portion, close to the photoelectricity portion, of the edge of the pure electricity portion, and connected with the metal wire on the side face of the carrier piece through a metal bonding wire. According to the structure of the optical transceiver module, the purpose that in the optical transceiver module, the direction of the optical fibers is parallel to the plane of a circuit board is achieved.

Description

technical field [0001] The invention relates to a photoelectric device, in particular to an optical transceiver module. Background technique [0002] Although the vertical cavity surface emitting laser (VCSEL) and the surface receiving detector are directly coupled face-to-face with the fiber, although the coupling efficiency is high, the direction of the fiber is perpendicular to the vertical cavity surface emitting laser (VCSEL) and the surface receiving detector; usually, the vertical cavity surface emitting laser ( VCSEL) and the upper and lower surfaces of the surface photodetector are parallel to the plane of the circuit board, so the direction of the optical fiber and the plane of the circuit board are perpendicular to each other at this time; due to the limited bending radius of the optical fiber, especially the large bending radius of the optical fiber ribbon, so The application scenario of this coupling method requires a larger space in the vertical direction of th...

Problems solved by technology

[0006] In addition, optical transceiver modules and components can be divided into pure electrical parts and optoelectronic parts. Due to the unbalanced technology maturity, the technical difficulties of the optoelectronic part are relatively high, and the entry threshold is relatively high. Field Constraints
