Optical modules are electronic devices that transmit data over long distances using light waves. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. As an essential component of optical fiber communication, optical modules are optoelectronic devices that facilitate the conversion between optical and electrical signals during the transmission process. As the core optoelectronic devices operating at the Physical Layer of the OSI model, their primary function is to perform electro-optical and photo-electric conversion during signal. Optical modules are essential components in modern communication networks, enabling high-speed data transmission over fiber optic cables. These modules typically consist of a transmitter, which converts electrical signals into a light signal, and a receiver, which converts the received signal back. In the world of fiber optic communications, optical transceiver modules play a pivotal role as interfaces that convert electrical signals to optical signals and vice versa.
