The optical module is a photoelectric conversion module, which converts the electrical signal of the device into an optical signal, so that it can propagate in optical fibers. It has advantages that cable propagation does not have, such as transmission distance, transmission rate, etc. After reaching the destination, the optical signal is converted back into an electrical signal through the optical module for equipment use. The optical module is just a conversion device that needs to be plugged or soldered onto the equipment for use.

Optical module is an electronic component for photoelectric conversion. Simply put, optical signals are converted into electrical signals, and electrical signals are converted into optical signals. It includes transmitting devices, receiving devices, and electronic functional circuits. According to its definition, wherever there is a light signal, there will be an application of light modules.
