The optical module works in the physical layer of the OSI model and is one of the core devices in the optical fiber communication system. It is mainly composed of optoelectronic devices (optical transmitter, optical receiver), functional circuits and optical interfaces, etc. Its main role is to realize the photoelectric conversion and electro-optical conversion functions in optical fiber communication. The working principle of optical module is shown in the working principle diagram of optical module.
