Description

technical field [0001] The present invention relates to the technical field of optical fiber communication, and more specifically relates to a multi-channel optical module and an optical fiber communication system. Background technique [0002] With the development of science and technology, high-speed transmission signal technology is widely used, optical interconnection can transmit signals over a much wider bandwidth than electrical transmission, and use small-sized, low-power optical modules to construct signal transmission systems. In the optical module, optical fiber is used as the transmission medium. Compared with electrical communication such as cables or microwaves, optical fiber communication has the advantages of wide transmission frequency, weak signal crosstalk, anti-electromagnetic interference, large communication capacity, small transmission attenuation, and long transmission distance. . [0003] In the prior art, both the electrical signal processing and t...
