Abstract

The invention discloses a parallel optical assembly. The PCB of the parallel optical assembly comprises a rigid PCB part and a flexible PCB part; the flexible PCB part can be folded or bended; an optical connector is arranged on a metal reinforcement plate in fixed connection with the flexible PCB part. In a packaging process, the optical connector and the metal reinforcement plate can bend or fold with the flexible PCB part, allowing the optical connector of an optical port packaging part to arrive at a most convenient assembling angle and position so as to realize rapid assembling, meanwhile helping reducing a packaging dimension, facilitating component high density distribution, and enhancing an adaptive capacity to environment. The parallel optical assembly can utilize the bending characteristic of the flexible PCB part to realize the overlapping installation of the parallel optical assembly, and guarantee optical connector and electric connector assembling precision so as to realize a compact structure of the parallel optical assembly; the packaging dimension is small, thereby facilitating the application of a parallel optical assembly high density integration communication system.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a parallel optical component. Background technique [0002] With the increasingly higher requirements for communication bandwidth in the field of optical fiber communication, the application of multi-channel parallel optical fiber transmission or parallel optical interconnection is becoming more and more extensive. In order to realize multi-channel parallel optical interconnection, multi-channel parallel optical transceiver modules are usually used Perform multiple parallel optical interconnections. [0003] Compared with single-channel modules, parallel modules require higher component density, smaller package size and weight, and lower energy consumption. At the same time, thermal design, electromagnetic interference shielding design, packaging process design, photoelectric coupling design and circuit design There are higher requirements. The perfect struc...
