Abstract

The invention relates to a parallel light transmitting and receiving assembly for broadband high-speed transmission. A signal input port is formed at one end of a first printed circuit board, a trans-impedance amplifier (TIA), a laser driving chip, a photoelectric detector (PD) array and a VCSEL perpendicular cavity transmitting laser array are packaged on the surface of a second printed circuit board, the front end of an optical fiber array is placed in an optical fiber fixing assembly, the optical fiber array aligns at the PD array in a coupling mode, and the optical fiber array aligns at the VCSEL perpendicular cavity transmitting laser array in a coupling mode. The optical fiber fixing assembly comprises a base, an optical fiber orientation conversion piece base plate and a covering plate, slant steps are arranged on the surface of the optical fiber orientation conversion piece base plate, a V-shaped groove is carved in an upper step, a lower step is a plane, bare fibers of an optical fiber array are placed in the V-shaped groove, the covering plate covers the V-shaped groove, and the optical fiber orientation conversion piece base plate, the covering plate and the base are connected through fixing glue. The technology combining a soft plate and the hard plate is adopted, and optical coupling is carried out on the VCSEL perpendicular cavity transmitting laser array and the PD photoelectric detector array by the driving aligning technology.

Description

technical field [0001] The invention relates to a parallel optical transceiver assembly for broadband high-speed transmission, in particular to a parallel optical transceiver assembly for broadband high-speed transmission and an optical fiber fixing part thereof. Background technique [0002] With the improvement of high-speed signal transmission requirements, parallel optical transceiver components emerged as the times require. The parallel optical module is to realize the mutual conversion of multiple electrical signals and optical signals in a single structure, so as to realize the function of sending and receiving. Due to the high bandwidth density and low power consumption brought about by device integration and miniaturization, the transmission bandwidth and power consumption of the parallel optical module are much better than multiple discrete devices, thereby improving the transmission performance of the system. [0003] However, the existence of multiple discrete c...
