On the morning of August 21st, optical module CPO (co-packaged optics) stocks rallied sharply, with Eoptolink Technology Inc.,Ltd. (300502) leading the charge with a gain of over 7%, while Zhongji Innolight and Tianfu Communication each advanced by more than 4%. Among popular ETFs, the ChiNext AI ETF HuaBao (159363), which heavily weights these optical module CPO leaders, surged upward on the exchange with notable volume expansion.
Co-packaged optics (CPO) is transitioning from the technical roadmap to mass production. Nvidia's recent announcement of large-scale CPO manufacturing signals a rapid shift in AI data center interconnect methods from "electricity" to "light"—co-packaging switch chips with optical engines can significantly reduce power consumption and latency, serving as a critical foundation for next-generation 10,000-card and 100,000-card clusters. This industrial inflection point has opened incremental growth space for the entire optical interconnect chain, moving from "thematic expectations" to "order fulfillment."
Changjiang Securities noted that Lumentum and Coherent have shown improving performance and profitability, with 1.6T optical modules, laser chips, and NPO accelerating. The optical communications sector's prosperity continues to rise. The renewed large-scale expansion of high-end laser chip production underscores confidence in AI data center demand and long-term growth. The firm remains firmly bullish on the AI and computing power theme, recommending attention to optical module and other optical communication industry chains.
To position along the high-brightness "optical" theme, the ChiNext AI ETF HuaBao (159363) and its off-exchange feeder funds (Class A 023407, Class C 023408) focus on optical module CPO leaders while also balancing AI applications. The underlying index holds approximately 40% in "Zhongji Innolight + Eoptolink + Tianfu Communication," making it a core flagbearer for AI computing power.
