Yangtze Optical Fibre and Cable has issued a notice regarding unusual stock trading activity, highlighting the recent surge in market interest surrounding optical fibre and cable products related to data center computing power, particularly focusing on hollow-core optical fibre. While demand for data center-related optical fibre and cable products constitutes a minor portion of global demand, hollow-core optical fibre, as an avant-garde technology, remains in its nascent stages of application. It has yet to achieve significant sales volumes or establish stable pricing and profit margins. Further maturation of the industrial chain is crucial for the advancement of this business segment. Currently, the hollow-core optical fibre business has a minimal impact on the company's financial data, prompting investors to exercise caution, recognize associated risks, and approach investments with rationality and prudence.
