YOEC Showcased Innovations at DOFS Conference

From November 22 to 24, 2024, the inaugural Distributed Optical Fiber Sensing Technology and Application Conference was grandly held in Nanjing. As the first large-scale comprehensive academic conference focusing on distributed optical fiber sensing technology (DOFS) in China and abroad, it attracted numerous experts, scholars, and technical leaders from various fields. Participants shared cutting-edge research results and discussed application challenges, providing an important platform for the transformation of DOFS from academia to industry. Yangtze Optical Electronic Co., Ltd. (YOEC, stock code: 688143) was invited to participate and shared its research achievements and experiences in the preparation and application of specialty optical fibers.

With the rapid development of China’s economy, the total scale of large infrastructure construction has surpassed that of other countries combined. Health monitoring of these infrastructures has become a key societal focus. DOFS technology, capable of real-time monitoring of various physical parameters at any point along the optical fiber, has emerged as an ideal choice in sectors such as energy, power, aerospace, communications, transportation, and security. It is also a critical strategic technology in international competition.

On November 23, the conference’s opening ceremony was hosted by Professor Guan Bai’ou from Jinan University. Notable keynote speeches were delivered by Academician Liu He from the Exploration and Development Research Institute of China National Petroleum Corporation, Professor Rao Yunjiang from the University of Electronic Science and Technology of China, and Professor Gang-Ding Peng from the University of New South Wales, Australia.

On November 24, during the “Distributed Optical Fiber Sensing Devices and Modules” session, Dr. Qin Yingchun from YOEC’s R&D Center presented a report titled Preparation and Application of Specialty Optical Fibers for Optical Fiber Sensing. The report explored the temperature characteristics of polarization-maintaining (PM) fibers used in fiber gyroscopes and extended the discussion to the field of DOFS. Dr. Qin proposed optimization directions in fiber design, material selection, and fiber drawing and cabling techniques. The presentation highlighted YOEC’s recent advancements, including the development of the domestically produced second-generation low thermal expansion coefficient polymer material, as well as critical components such as 40/80 and 50/80 ultra-thin PM fibers and 60/100 thin-diameter PM photonic crystal fibers. Additionally, YOEC successfully developed intelligent winding and automated bonding technology for fiber coils. Notably, a 930-meter 60/100 thin-diameter PM photonic crystal fiber coil produced with YOEC’s sixth-generation automated winding equipment achieved an all-temperature accuracy of 0.008°/h without temperature compensation. This breakthrough meets the demands for high performance, cost-efficiency, and miniaturization in fiber gyroscopes, laying a solid foundation for the advancement of fiber gyroscope technology.

YOEC remains committed to technological innovation and application expansion, focusing on the R&D and production of specialty optical fibers. Through continuous technology iteration and process improvement, the company has enhanced the performance and consistency of various optical fiber products, including PM fibers, while effectively reducing production costs. Furthermore, YOEC actively builds and refines optical fiber sensing system solutions, strengthens cooperation across the industry chain, and promotes the widespread application of optical fiber sensing technology in key areas such as marine exploration, land monitoring, aerospace, power transmission, petrochemicals, architecture, rail transportation, healthcare, and environmental protection.
