Yangtze Optical Fibre and Cable has issued an announcement regarding unusual stock trading activity, highlighting the recent surge in market interest towards optical fibre and cable products specifically tailored for high-performance data centers, particularly hollow-core optical fibres. Despite the fact that these data center-related products constitute a minor fraction of the overall global demand, hollow-core optical fibres, as an avant-garde technology, have garnered considerable attention. Nonetheless, their application is still nascent, with neither substantial sales nor stable pricing and profitability achieved yet. Furthermore, the development of this business segment hinges on the continued maturation of the industry chain. At present, the hollow-core optical fibre business has a limited impact on the company's financial performance. Investors are thus advised to remain vigilant of associated risks and approach investments with rationality and prudence.
