# YOFC: The hollow core fiber-related business has not yet had a significant impact on the company's financial data

According to the Zhitong Finance APP, YOFC (601869.SH) announced that the closing price of the company's stock from September 16, 2025, to September 18, 2025, has cumulatively deviated by more than 20% over three consecutive trading days, indicating significant price volatility.

The announcement stated that the company has noticed recent market attention on optical fiber and cable products related to computing power data centers, especially hollow-core fibers. Currently, the proportion of optical fiber and cable products related to data centers in the total global demand for optical fibers and cables is relatively small. Among them, hollow-core fibers, as cutting-edge products in the industry, are still in the early stages of application, with no large-scale sales, stable pricing, or profit levels formed yet. The subsequent business development also depends on the further maturity of the industry chain. At present, the hollow-core fiber-related business has not yet had a significant impact on the company's financial data
