According to the invention, through the unique structural design of the light emitting assembly, the light path is completely sealed and packaged.

Description

technical field [0001] The present application relates to the technical field of optical fiber communication, and in particular, to an optical module. Background technique [0002] With the development of new business and application models such as cloud computing, mobile Internet, and video, the development and progress of optical communication technology has become more and more important. In the optical communication technology, the optical module is a tool for realizing the mutual conversion of photoelectric signals, and it is one of the key components in the optical communication equipment. With the development of the optical communication technology, the transmission rate of the optical module continues to increase. [0003] With the increase of the communication rate, although the power consumption per unit bandwidth is decreasing, the overall power consumption of the optical module is still further increasing. Most of the heat dissipation methods used in the client e...

Problems solved by technology

[0004] However, due to the low-cost requirements of the optical modules deployed in the data center, the light emitting and receiving components mostly use non-sealed design structures, and their key optical paths are all open. When the optical modules enter the cooling liquid with the switch, these key optical paths And components will also enter the cooling liquid, resulting in changes in the optical mechanism and pollution of the optical surface, seriously affecting the normal operation of the optical module
