Sichuan Huiyuan Optical Communications Co., Ltd. (000586.SZ) has issued an announcement stating that its stock price recorded a cumulative deviation exceeding 20% over three consecutive trading days on April 7, 8, and 9, 2026, which constitutes abnormal trading fluctuations according to Shenzhen Stock Exchange regulations. The company noted recent market attention on improved supply-demand dynamics for fiber optic products, as well as heightened interest in fiber optic cables and optical modules related to computing data centers. However, the company clarified that it currently has no business operations, orders, or technical reserves in these areas. Its main operations consist of power optical cables, online monitoring devices for power systems, and plastic optical fibers. The company does not possess manufacturing capacity for quartz fiber preforms or quartz fibers, and all quartz fibers required for power optical cable production are externally sourced. Power optical cables are used as complementary products in the power market, while plastic optical fiber series are mainly applied in decorative lighting, industrial control, power equipment, and consumer electronics. Industrial control optical devices compatible with plastic optical fiber communication, with speeds below 100 Mbps, are primarily used in sensor units for automated production lines and control signal transmission for high-voltage frequency converters—not for high-speed optical modules required in data centers or AI computing applications.
