On September 20, 2025, the 13th China Optical Fiber Sensing Conference grandly opened in Wuhan. Dr. Lian Zhenggang, Technical Director of Yangtze Optical Electronic Co., Ltd. (YOEC, stock code: 688143), was invited to deliver a keynote report at the sub-forum “New Technologies and Products in Optical Fiber Sensing”. His presentation highlighted the company’s latest technological breakthroughs and product innovations in the field of specialty optical fiber applications, fully demonstrating YOEC’s comprehensive strength and industry-leading position in high-end fiber sensing applications.

Dr. Lian began by outlining YOEC’s development profile and technological positioning. He emphasized that the company remains committed to building an internationally advanced “optical fiber coil and specialty optical fiber technology platform”, focusing on providing high-performance specialty optical fiber materials for communications, sensing, power transmission, and integrated applications. YOEC’s products are widely used in extreme environments and complex scenarios such as aerospace, marine exploration, underground, downhole, and even biomedical applications, showcasing excellent environmental adaptability and technological foresight.

During the forum, Dr. Lian introduced two categories of high-end products: ultra-fine polarization-maintaining fibers for gyroscope coils and ultra-fine bend-resistant fibers for hydrophone coils. As fiber optic gyroscope systems continue to pursue miniaturization and higher precision, YOEC’s ultra-fine polarization-maintaining fibers, with their outstanding performance, effectively meet the demands of smaller size and higher reliability, making them highly valuable in aerospace, marine exploration, and resource prospecting.

In addition, the report highlighted multi-core spun fibers and fiber Bragg gratings (FBG) as new specialty fiber products and technologies, reflecting YOEC’s diversified layout in material systems and fiber structure innovation. The company has now established a complete sensing fiber product portfolio covering polarization-maintaining, single-mode, and special-application categories. With strong customization capabilities, YOEC can efficiently respond to the diverse application needs of different customers.

“Innovation never stops, contributing to the future of the industry.”

YOEC remains committed to advancing specialty optical fiber technology and expanding its applications. Looking ahead, the company will continue to deepen R&D, broaden the boundaries of innovation, and inject fresh momentum into the upgrading of China’s high-end manufacturing and optical fiber sensing technologies.

The presentation drew significant attention from attending experts. Multiple organizations expressed strong interest in YOEC’s products and engaged in in-depth discussions on potential cooperation opportunities.
