CITIC Securities has highlighted that the substantial capital inflow into the AI computing infrastructure sector continues to surge, underscoring the enduring investment appeal of this industry amidst rapid technological advancements. Presently, the market is witnessing a peak in the large-scale deployment of 800G optical modules, while the rollout of 1.6T products is gaining momentum. Concurrently, next-generation optical interconnection technologies, including silicon photonics integration, NPO (Near-Packaged Optics), and CPO (Co-Packaged Optics), are steadily maturing. Leveraging their early-mover advantage and robust production capabilities, China’s leading optical module manufacturers are well-positioned to sustain their leadership roles within the global computing infrastructure supply chain. Furthermore, with ongoing increases in AI-related capital expenditures globally, the computing infrastructure landscape is expanding from training-centric applications to inference-driven scenarios. It is advisable to closely monitor opportunities in supporting computing infrastructure areas, such as optical modules, optical chips, AIDC (Artificial Intelligence Data Centers), switches, and servers.
