Changes in Hong Kong stocks | Changfei Optical Fiber Cable (06869) rose by more than 9% in a month and surged by more than 50%. Demand for air core fiber is expected to benefit from AI catalysis

The Zhitong Finance App learned that Changfei Optical Fiber Cable (06869) has increased by more than 9%, and the cumulative increase during the month has already exceeded 50%. As of press release, it rose 7.44% to HK$55.5, with a turnover of HK$700 million.

On the news, the “Research Report on the Development and Application of Information Photonics Technology (2025)” was officially released. The report points out that hollow fiber has the advantages of low latency, wide spectrum, low loss, and low nonlinear effects, and is a disruptive solution to the physical bottlenecks of traditional optical fibers. At present, air core fiber is in a critical window of rapid iterative evolution. Huaxi Securities believes that hollow fiber is still in the early stages of commercialization, but its characteristics such as low latency, wide spectrum, and low loss are expected to gradually increase demand for large AI model connections. Its multiple potential values are highlighted, including internal interconnection, metropolitan data center interconnection, and wide-area connectivity, all of which have obvious advantages.

According to public information, Changfei Optical Fiber Cable develops high-value-added products such as multi-mode and air-core optical fibers on the basis of traditional optical rod optical fiber services, while actively diversifying. The company recently announced that the company issued 70 million new H shares, with a net proceeds of approximately HK$2,229 billion. According to the announcement, about 80% of the placement capital will be used to develop the company's overseas business, and about 20% will be used as general working capital.
