An optical module is a complete communication device that integrates optical chips with various electronic and optical components. Its primary function is to perform the conversion between electrical signals and optical signals while providing a standardized interface for. An optical chip is a semiconductor device designed to perform optical or optoelectronic functions. 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 AI large-scale models accelerate their iteration, computing power clusters are moving from "thousands of cards" to "tens of thousands of cards" and "hundreds of thousands of cards. " As the "blood vessels" connecting computing power, the internal hierarchical relationships of optical. The Transmitter Optical Sub Assembly (TOSA) is responsible for the emission of light.
