Hong Kong stock concept tracking | Domestic breakthrough! 170GHz ultra-wideband photonic chip is born. Institutions are optimistic about domestic high-speed optical module companies benefiting (with concept stocks)

On May 16, the National Information Optoelectronics Innovation Center has developed the world's first 170GHz ultra-wideband device product using independently developed ultra-wideband photon chip technology, which has been applied to domestically produced optoelectronic measurement equipment. In the future, this technology will provide underlying support for 6G communication and will be used in next-generation high-speed optical module products. From the application perspective, the value of this domestically produced ultra-wideband photon chip far exceeds the current situation, providing profound empowerment in multiple cutting-edge fields. Officials from the National Information Optoelectronics Innovation Center stated that this chip will extend into various application scenarios in the future, with the most attention given to the high-speed optical module field. Leveraging revolutionary thin-film lithium niobate materials and heterogeneous integration technologies, this chip is expected to be widely used in next-generation high-speed optical modules of 1.6T and above, helping the optical module industry achieve iterative upgrades and alleviate the challenge of mismatch between AI computing power and data transmission rates. Furthermore, this chip will also provide core underlying support for 6G "Space-Terrestrial-Integrated" communication. As a defining feature of 6G, Space-Terrestrial-Integrated communication requires breaking the coverage boundaries of ground networks to achieve seamless global connectivity. The high bandwidth and low latency characteristics of ultra-wideband photon chips can meet this demand, and there are prospects for further applications in satellite communication equipment development, contributing to a significant advancement in China's 6G technology. Additionally, in the AI data center field, this chip can further enhance transmission rates and reduce latency, providing more efficient underlying support for AI large model training, cloud computing, and other scenarios. Optical modules are the "blood vessels" of AI computing infrastructure, bearing the responsibility of high-speed data transmission between GPU clusters, switches, and servers. In the era of AI large models with tens of thousands or millions of GPU cards, traditional electrical interconnects have approached the physical limits of bandwidth, latency, power consumption, and cost, making optical interconnects a core breakthrough. NVIDIA founder Huang Renxun stated in May 2026, "The next generation of AI infrastructure will require a large number of optical connections, as copper wires are no longer able to meet the demand." With the acceleration of AI computing infrastructure, the demand for optical modules is significantly increasing. In terms of market size, TrendForce data shows that the global market size of AI-specific optical transceivers is expected to surge from $16.5 billion in 2025 to $26 billion in 2026, with an annual growth rate of over 57%. LightCounting data shows that the Ethernet optical module market is expected to grow by 65% in 2026. Goldman Sachs further predicts that the addressable market for optical interconnects will expand from about $15 billion currently to approximately $154 billion in 2027-2028, nearly a tenfold increase. Founder believes that the high-speed optical module market will continue to benefit from the high investment in North American CSP26 Capex, driven by the huge demand for AI computing training and inference, leading to the deployment of AI computing cluster scale-up/scale-out networks. Domestic high-speed optical module companies are expected to maintain high industry vitality. Wanalyst Securities suggests focusing on investment opportunities in the core materials, optical components, and optical chip fields upstream of the high-speed optical module and optical communication industry chain, as well as leading enterprises in CPO and OCS technology deployment. Related concept stocks: - Cig Shanghai (06166): Cig Shanghai disclosed its first quarter performance, achieving operating income of RMB 1.287 billion, a year-on-year increase of 43.98%; net profit attributable to shareholders of the listed company was RMB 118 million, a significant increase of 276.44% year-on-year. The main driver of the high growth in performance is the significant increase in the scale of the high-speed optical module business, with continued strong demand for 800G and 1.6T high-speed optical modules in global data centers. Current public information shows that there is continued strong demand for 800G and 1.6T high-speed optical modules in global data centers, and Cig Shanghai is continuing to expand production. Its factories in Jiashan and Malaysia are gradually increasing capacity, and the construction of production capacity at its facility in Mexico is actively progressing to meet market delivery pressures. The company expects that 800G optical modules will remain its main product line in 2026. - Ningbo Joyson Electronic Corp. (00699): Ningbo Joyson Electronic Corp. reported its performance for the year 2025, achieving total operating income of RMB 61.183 billion, a year-on-year increase of 9.5%; and net profit attributable to owners of the parent company of RMB 1.336 billion, a 39.1% increase year-on-year. In 2025, the company's new business order scale surpassed approximately RMB 97 billion, achieving new breakthroughs from zero to one in the layout of emerging businesses such as smart driving and central computing units, laying a solid foundation for the rapid growth of its automotive electronics business. It is worth mentioning that recently, Ningbo Joyson Electronic Corp. completed a strategic investment in the optical module company Newfiber. - TIME INTERCON (01729): CMSC previously pointed out that the company is a core supplier for Google MPO in China, with the potential for medium to long-term growth driven by AI computing, automotive, and medical industries. Looking ahead, the expected high growth in AI computing demand is likely to support the company's businesses in MPO, servers, and high-speed copper cables. Industrial believes that the company's core customer base is tied to overseas leading cloud providers, with optical interconnect products such as MPO high-density fiber solutions being the main source of revenue. The company has already entered the supply chain of major North American customers and will continue to strengthen its supply chain advantage. - YOFC (06869): YOFC reported operating income of RMB 3.695 billion in the first quarter, a year-on-year increase of 27.70%; net profit was RMB 495 million, a significant increase of 226.40% year-on-year. UBS stated that the company's first-quarter net profit of RMB 495 million was lower than the market's expected range of RMB 800 million to RMB 1 billion, which may result in a short-term negative market reaction. However, the bank maintains confidence in the company's future profit growth, believing that the increase in fiber optic prices has yet to be fully reflected, and with the continued increase in data center demand, the company is expected to meet the bank's full-year forecast. Huatai, on the other hand, pointed out that the company's first-quarter profit growth far exceeded the revenue growth, mainly due to a significant improvement in gross profit margins. Fiber optic prices showed a monthly uptrend in the first quarter, and the company still had some low-priced long-term contracts in its delivery structure during the reporting period. As high-priced orders concentrate in the second quarter, there is optimism that profit flexibility is likely to accelerate. The rising prosperity of the fiber optic cable main business and the dual driving forces of optical interconnect components and other diversified businesses are expected to significantly increase the company's performance. The rating of "Neutral" is maintained.
