Abstract

The invention relates to a parallel optical transceiver module used for broadband high-speed transmission. A signal input port of a gold-plated plugboard structure is formed at one end of a first printed circuit board, and a trans-impedance amplifier (TIA), a laser driving chip, a photoelectric detector (PD) array, a vertical cavity surface emitting laser (VCSEL) array and a spacer are arranged on the surface of a second printed circuit board. The front end of a fiber array is arranged in a fiber fixing component, and the fiber array is aligned to the PD array and the VCSEL array in a coupled mode. The fiber fixing component comprises a fiber orientation conversion piece bottom board, a covering board and fastening bolts, a V-shaped groove is carved in the surface of the fiber orientation conversion piece bottom board, bare fibers of the fiber array are placed in the V-shaped groove, the covering board covers the V-shaped groove, and holes matched with the fastening bolts are formed in the fiber orientation conversion piece bottom board, the spacer and the second printed circuit board. The parallel optical transceiver module used for broadband high-speed transmission achieves optical packaging with high coupling efficiency, and reduces stick-mounting accuracy of the photoelectric component arrays and technological difficulty of connection of the photoelectric components and the fibers.

Description

technical field [0001] The invention relates to a parallel optical transceiver assembly for broadband high-speed transmission, belonging to the technical field of communication. Background technique [0002] With the improvement of human requirements for high-speed signal transmission, parallel optical transceiver components have emerged. 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 components makes the assembly error allowed for parallel optical module packaging smaller, re...
