The production of optical modules in a factory is a complex process that integrates semiconductor chips, optoelectronic components, and precision assembly to create high-speed, reliable devices for telecom networks, data centers, and AI applications. The optical module is one of the core devices of the optical communication system, and its development has a vital impact on its related industrial chain, from the upstream industry chip substrate, PCB to the downstream telecom market and data communication market, and the field of lidar driverless. 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. Operating at the physical layer of the OSI model, optical modules are core devices in optical. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications.
