As the global AI computing power competition intensifies, the demand for high-speed optical modules within and between data centers has surged. The 800G and 1.6T optical modules have entered the mass delivery or sample testing phase, coupled with giants like NVIDIA continuously increasing investment in computing power infrastructure, the optical communication industry chain is entering a period of simultaneous volume and price increase.
In terms of technological breakthroughs, NVIDIA's CPO switch has officially entered mass production, marking a milestone catalyst. On May 28th, NVIDIA announced at the GTC conference that its world's first CPO Ethernet switch has been fully mass-produced, which directly stimulated the A-share optical communication sector, with leading stocks like Tianfu Communication, Zhongji Innolight, and Xinyi Sheng all reaching historical highs that day.
On the order front, the leading optical module companies continue to experience high demand. Zhongji Innolight clearly stated on May 15th that the orders and shipments of its high-end optical module products are continuously increasing, with the 1.6T products already in mass shipment and continuing to ramp up, while the 3.2T products are still under ongoing research and improvement. The company's supply chain is stable, ensuring high-quality order delivery through the introduction of alternative suppliers and signing guarantee agreements.
In terms of institutional views, several leading brokerages are bullish on the optical module main line. Guosheng Securities released a research report on May 24th, pointing out that as June approaches, the demand expectations for 2027 are gradually becoming clear, while the supply shortage of core upstream optical communication components is expected to gradually ease. The performance of leading companies like Zhongji Innolight and Xinyi Sheng is expected to accelerate, and we recommend returning to the &#34;big optics&#34; main line; Kaiyuan Securities noted in its mid-2026 investment strategy that 2026 may become the year of mass production for 1.6T optical modules, with silicon photonics technology accelerating its implementation, likely becoming the mainstream solution for 1.6T high-speed optical modules.
