Changfei Fiber Optics: The related business of hollow-core optical fibers has not yet had a significant impact on the company's financial data, and there is uncertainty in future development.

Jin10 Data, July 30th, reported that Changfei Fiber Optics announced that the cumulative closing price fluctuation deviation of its stock exceeded 20% over three consecutive trading days from July 28 to July 30, 2025, which falls under the category of abnormal stock trading fluctuations. The company has noted that there has been a high level of attention in the market towards computing power data center-related fiber optic cable products, particularly hollow core fibers. The proportion of fiber optic cable products related to data centers in the total global demand for fiber optic cables is relatively small. Among these, hollow core fibers, as a cutting-edge product in the industry, are still in the early stage of application, and have not yet formed large-scale sales or stable pricing and profit levels. The transition of hollow core fibers from early trial validation to large-scale commercial use requires further maturation of the product and the industrial chain. Currently, the relevant business has not had a significant impact on the company's financial data, and there is uncertainty regarding future developments.
