Description

technical field [0001] The invention relates to optical communication technology, in particular to an optical module. Background technique [0002] Optical fiber communication is a communication method in which light waves are used as information carriers and optical fibers are used as transmission media. With its wide transmission frequency band, strong anti-interference ability, and small signal attenuation, optical fiber communication gradually replaces cable, microwave and other communication methods, and has become the most widely used communication method in the field of communication. [0003] The optical module is a very important optical signal interface device in optical fiber communication. One end of the optical module is connected to the optical fiber as an optical interface, and the other end is connected to external communication equipment as an electrical interface. Optical modules can convert optical signals and electrical signals. figure 1 is a schematic ...
