Ping An Securities research report pointed out that optical modules are an essential component of telecommunications and data communication infrastructure construction. With the rapid growth of AIGC computing facility construction, the network architecture of data centers has also undergone significant changes, and the demand for optical modules in the field of data communication, especially for 800G+ modules, has grown rapidly. Domestic manufacturers, as important components of the optical module industry chain, have grown rapidly in this round of demand growth and technological evolution in recent years. In the future, with the enrichment of AIGC application requirements, computing infrastructure construction will take another step, and the domestic optical module industry chain will continue to benefit. It is recommended to pay attention to: 1) upstream component suppliers such as Source Photonics; 2) platform-type component manufacturers such as Suzhou TFC Optical Communication; 3) optical module suppliers such as Zhongji Innolight and Advanced Fiber Resources.
