Optical Module is an optoelectronic conversion accessory and one of the core devices in the field of optical communication transmission. It is composed of optoelectronic devices (transmitters and receivers), function circuits and optical interfaces.

   The optical module is a conversion device for photoelectric signals that needs to be inserted on the device. The telecommunications signal and the light signal are a magnetic wave signal. The transmission range of the electrical signal is limited, and the optical signal can be transmitted faster and farther, but some of the current equipment recognition is the electrical signal, so there will be a photoelectric conversion module. The use of the light module is to transform the electrical signal into a optical signal. After transmitting through the optical fiber, the receiving end will convert the optical signal into a electrical signal.
