Main BusinessR&D, production, sales, and service of fiber optic gyroscope core components (fiber optic coils) and integrated solutions.
Company ProfileWuhan Changyingtong Optoelectronic Technology Co., Ltd. is a national-level specialized, sophisticated, and innovative "Little Giant" enterprise. It specializes in the R&D, production, sales, and service of fiber optic gyroscope core components (fiber optic coils) and integrated solutions. The company is dedicated to pioneering the high-tech industrial application of fiber optic coils and their key material, specialty optical fibers, primarily in the military inertial navigation field.
The company holds 95 patents, including 54 invention patents, and has participated in multiple major research projects organized by relevant ministries and commissions. Its self-developed fiber optic coils achieve ultra-high precision, high stability, and strong environmental adaptability, meeting application requirements in various environments such as aerospace. The independently developed ultra-fine diameter polarization-maintaining fiber enables miniaturization of fiber optic coils, thereby solving the technical challenge of miniaturizing fiber optic gyroscopes. Various customized adhesives for coil winding effectively match different types of polarization-maintaining fibers, enhancing the windability, vibration resistance, and full-temperature characteristics of the coils. The self-developed specialty fiber coatings reduce the risk of fiber damage during use, effectively ensuring the long-term reliability of the products. The independently developed fiber optic coil winding equipment can complete batch winding of high-precision fiber optic coils through semi-automated operation, significantly improving production efficiency.
