On the morning of August 17, NVIDIA officially announced the mass production of CPO (Co-Packaged Optics) switches, triggering a broad rally in CPO concept stocks. Shares of TFC Communication surged over 7%, while TFC Optical Communication and other related stocks gained more than 7%, and Zhongji Innolight rose over 1%.
Among the popular ETFs, the ChiNext Artificial Intelligence ETF (159363), which heavily holds CPO leaders, saw its intraday price rise more than 1.5% with noticeably increased trading volume compared to the previous session. Co-packaged optics (CPO) is moving from technology roadmaps to mass production floors. NVIDIA's recent announcement of scaled CPO production signals that AI data center interconnect methods are accelerating a shift from "electrical" to "optical"—co-packaging switch chips with optical engines can significantly reduce power consumption and latency. This is a critical foundation for supporting next-generation clusters of tens of thousands or even hundreds of thousands of GPUs. This industrial inflection point unlocks incremental growth for the entire optical interconnect chain, moving from "thematic expectations" to "order fulfillment."
Within the CPO optical interconnect value chain, optical components and optical engines are the core incremental segments. Suzhou Tfc Optical Communication Co., Ltd., a company deeply involved in precision optical communication devices, is actively participating in CPO-related optical engine supporting products. It is expected to directly benefit from component demand during this volume ramp-up, drawing sustained market attention to its earnings elasticity and industry position.
From a capital market perspective, the ChiNext Artificial Intelligence Index has a particularly pure exposure to "optical." Among its constituent stocks, Suzhou Tfc Optical Communication Co., Ltd. holds a significant weight, making this index one of the most sensitive to CPO and optical module themes currently. In other words, allocating to this index serves as a one-basket approach to investing in optical interconnect assets with the highest "CPO concentration," balancing purity with diversification.
To position along the high-"optical" main line, the ChiNext Artificial Intelligence ETF (159363) and its feeder fund (Class A: 023407, Class C: 023408) focus on leading CPO optical module companies while also covering AI applications. The underlying index has a combined weight of approximately 40% for Zhongji Innolight, Eoptolink Technology, and Suzhou Tfc Optical Communication Co., Ltd., positioning it as a core AI computing power holding. The ChiNext Artificial Intelligence ETF (159363) currently has a scale of about 7 billion yuan, with an average daily turnover exceeding 1 billion yuan over the past six months, leading the eight ETFs tracking the same index in both scale and liquidity.
