"The light" is too strong! Zhongji Innolight's stock price surpasses Moutai, and Nvidia names TFC as a contributor, the communication ETF GF Fund CNI Communication ETF (159507) soars 6%

As of the lunch break, the A-share market has surged significantly, with the Sci-Tech 50 Index rising over 4% and the ChiNext Index increasing nearly 4%. The "light" market has fully exploded, with the CPO concept continuing its strong performance, and the optical fiber concept repeatedly strengthening. Hengtong Optic-Electric and Yangtze Optical Fibre both achieved two consecutive trading limits, while TFC rose over 10% and Yuanjie Technology increased over 15%, reaching a historical high. Zhongji Innolight rose over 10%, with its stock price surpassing Kweichow Moutai and breaking 1,300 yuan, bringing its total market value to 1.46 trillion.

The communication ETF GF Fund CNI Communication ETF (159507) tracks the performance of the CNI Communication Index, with weighted stocks "Yizhongtian" (New Yisheng, Zhongji Innolight, TFC) accounting for over 32%, and the content of communication equipment reaching as high as 80.8%.

Domestically, the world's first S+C+L three-band ultra-low loss multi-core optical cable line was officially completed and opened in Qingdao, Shandong. This new type of optical cable line breaks the transmission capacity limit of traditional optical fibers. The new optical cable achieves "three-band parallel transmission," equivalent to widening information transmission from a "two-lane" to a "three-lane" highway, with single-core bandwidth increasing by nearly 50%, and the capacity of a single optical fiber reaching more than five times that of traditional optical fibers, fully meeting the future demands of AI intelligent computing and T-bit level ultra-high-speed transmission.

Overseas, at the Computex 2026 computer exhibition recently held in Taipei, Marvell CEO Matt Murphy and Jensen Huang appeared together, both emphasizing the importance of AI optical interconnect technology, considering it a key link in breaking through computing power bottlenecks. Marvell CEO Murphy stated that AI has raised new demands on infrastructure in recent years, with bottlenecks emerging in areas including computing power and memory. Now, the bottleneck is shifting again—what redefines the limits of infrastructure is connectivity. Jensen Huang expressed that when facing a computing problem, breaking down the computing task into many parts and distributing them across the entire data center, what is truly indispensable is connectivity. This is why Marvell is so important.

According to official news from NVIDIA, Spectrum-X Ethernet silicon photonics technology has now been fully mass-produced. The new generation of Spectrum-X switches is built on optical-electrical integrated packaging technology (CPO) and supports the Vera Rubin platform for horizontal scaling and cross-regional deployment of AI factories in data centers. Compared to networks using traditional transceivers, Spectrum-X Ethernet silicon photonics technology can achieve a fivefold increase in energy efficiency, a fivefold increase in AI uptime, and a 1.3 times faster deployment time.

It is worth noting that NVIDIA has explicitly mentioned the supply chain contributions of manufacturers such as TFC in the CPO mass production process, highlighting the core position of domestic optical module leaders in the global AI industry chain—"The laser chips from TFC are packaged into modules, providing the reliability required for AI workloads that need to operate year-round and around the clock."

Zhongyuan Securities pointed out that the communication equipment sector has performed outstandingly in the recent market, becoming an important force driving the A-share upward, especially playing a key role in stabilizing and rebounding after the Shanghai Composite Index received support at 4,032 points The current policy environment remains moderately loose, and with the economy gradually stabilizing, the communication industry, as an important part of the technology mainline, is expected to continue benefiting from the expansion of AI computing power demand and the process of domestic substitution, highlighting short-term allocation value.

Guosheng Securities stated that the long-term evolution logic of the computing power sector has not changed. As we enter June, the demand expectations for optical modules in 2027 are accelerating to become clearer, while the upstream core component supply shortage that previously constrained deliveries is gradually reaching an improvement turning point. The production capacity and performance elasticity of leading optical module manufacturers are expected to be released more rapidly.
