Abstract

The present invention relates to a multi-channel parallel bidirectional device coupling device, comprising a first lens array and a second lens array, the first lens array is used for arranging a transmitting end device and a receiving end device of a first optical signal, the second The lens array is used to arrange the transmitting-end device and the receiving-end device of the second optical signal, and the wavelengths of the first optical signal and the second optical signal are different. In the solution of the present invention, by setting two lens arrays, one lens array only needs to realize alignment of optical signals of one wavelength, greatly reducing alignment difficulty, and further improving alignment efficiency.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a multi-channel parallel bidirectional device coupling device. Background technique [0002] The main function of the optical transceiver integrated module (referred to as the optical module) is to convert the received optical signal into an electrical signal, and convert the electrical signal into an optical signal for transmission to realize data transmission. For short-distance high-speed optical modules, the standard SR4.2 uses dual wavelengths of 850nm and 910nm. Current low-cost designs are chip-on-board, such as figure 1 As shown, the transmitting end and receiving end of two wavelength optical signals are arranged on a lens array at the same time. Due to the need for multi-channel alignment at the same time, the combination of lens arrays requires high precision and is difficult to implement. Such as figure 1 As shown, for 8-channel transmission and rece...
