On April 7, San’an Optoelectronics announced that its optical communications segment has achieved notable progress in three key areas: high-speed optical chips, overseas market expansion, and automotive optical communications.

In the high-speed optical chip segment, the company has officially launched its 100G EML chip. The product is compatible with mainstream 800G optical module architectures and features a fully self-developed and vertically integrated design-to-manufacturing process, providing a critical domestically sourced component option for next-generation AI computing networks.

The high-performance optical chip market has long been dominated by a handful of U.S. and Japanese players, with relatively low localization rates in China; San’an’s move is expected to help ease supply-demand imbalances across the supply chain.

Regarding overseas expansion, San’an’s CW laser source products have been verified by leading international customers. The product lineup covers mainstream power specifications of 70mW and 100mW, supporting high-speed optical module applications ranging from 400G to 1.6T.

Amid the automotive intelligence trend, San’an is actively expanding into the automotive optical communications field. As autonomous driving places stringent demands on data transmission bandwidth and reliability, traditional transmission architectures face increasing challenges. In response, the company has developed automotive-grade optical chips capable of operating under harsh conditions and has established strategic partnerships with leading downstream players to jointly advance the commercialization of wide-temperature VCSEL and PD products.

San’an noted that, leveraging its vertically integrated manufacturing capabilities, its high-speed PD products for data center applications have already entered mass production. Meanwhile, the 100G EML, CW laser sources, and automotive optical chips are all ready for volume delivery.

It’s also worth noting that in collaboration with Tsinghua University and China Mobile, San’an has successfully developed a Micro LED light source device with high-speed modulation capability. Test results indicate a 3dB modulation bandwidth exceeding 7 GHz; based on communication models, its NRZ-OOK data transmission rate is expected to surpass 10Gb/s, laying a solid technological foundation for the development of short-reach high-speed optical interconnects and next-generation optical communication systems.
