Optical module is an optoelectronic device used for data transmission between communication devices, mainly responsible for photoelectric and electro-optical conversion. From a structural perspective, the optical module mainly consists of light emitting devices (TOSA, including lasers), light receiving devices (ROSA, including photodetectors), functional circuits, and optical (electrical) interfaces. In recent years, with the advent of the information and digital era and the rapid development of the Internet industry and AI...
