A 100g QSFP28 single receive single send high speed optical module

Abstract

The invention discloses 100G QSFP28 single-receiving single-transmitting high-speed optical module which comprises a fiber adapter. The right side of the fiber adapter is fixedly connected with a light transceiver module. The external surface of the light transceiver module is movably connected with a rubber protecting layer. One side, which is far from the light transceiver module, of the rubberprotecting layer is fixedly connected with a supporting frame. The external surface of a goldfinger is fixedly connected with a shielding layer. The external surface of the supporting frame is fixedlyconnected with a metal inner housing. The front surface and the back surface of the metal housing at the position of the fiber adapter are rotatably connected with a light shielding device. One side,which is far from the metal housing, of the light shielding device, and the approaching side of the light shielding device are fixedly connected with a fiber fixing device. The invention relates to the technical field of an optical module. The device is provided with the shielding layer and the light shielding device, thereby preventing mutual interference of the signal. Furthermore the device isprovided with the fiber fixing device, thereby preventing fiber loosening and ensuring normal signal transmission. Furthermore at the middle segment position, a flexible material is used as a supporting frame so that small-range inclination is allowed, thereby facilitating mounting.

Description

technical field [0001] The invention relates to the technical field of optical modules, in particular to a 100G QSFP28 single-receiving high-speed optical module. Background technique [0002] Various optical communication devices are being developed for the realization of an ultra-high-speed optical transmission system of 100 Gbit / sec or higher in order to increase the communication capacity. As an optical communication device used in an ultra-high-speed optical transmission system of 100 Gbit / sec or higher, an optical communication device utilizing digital coherent technology has attracted attention. In the digital coherent optical transmission and reception method, in order to transmit and receive data by utilizing the interference of light, when receiving data, local oscillation light is mixed with signal light, the signal is demodulated, and then digital signal processing is performed on it. Signal degradation such as wavelength dispersion or polarization mode dispersi...
