Optical modules are core components that enable ultra-high-speed, high-capacity, and low-latency data transmission in data centers, AI computing clusters, and high-speed communication networks. They also serve as the critical hardware foundation for supporting the training and inference of large AI models, cloud computing, and the construction of new infrastructure such as the "East-West Data Computing" initiative. Mid-to-high-end chip substrates are primarily used in optical modules with speeds of 400G and above. As core components, they enable high-reliability packaging, efficient heat dissipation, and stable high-speed signal transmission in high-speed optical modules, directly determining the operational stability and service life of these modules in scenarios involving high computing power, high power consumption, and high-density integration.
Driven by the rapid growth of the optical module market and continuous upgrades in product speeds, coupled with rising penetration rates of high-end products and increased configuration demands resulting from iterative technological advancements, the mid-to-high-end chip base market is experiencing strong momentum and high growth. Overall, the mid-to-high-end chip base industry is highly concentrated among leading optical module manufacturers. With strict supply chain certifications and strong partnership loyalty, leading companies are deeply tied to their core clients, resulting in a stable competitive landscape. Industry concentration is expected to further increase as products continue to move toward higher-end segments.
