High Performance Fiber Gyro Coil with Low Insertion Loss and High PER
Our company specializes in the professional design and manufacturing of optical fiber coils to meet customer and market application requirements. The φ50 low-precision fiber optic coil is engineered to satisfy the assembly, performance, and various environmental application needs of φ50 fiber optic gyroscopes.
Primarily used in closed-loop fiber optic gyroscopes with a diameter of approximately 50mm.
This optical fiber coil model utilizes a multi-pole symmetric winding method with 135μm thin diameter optical fibers and UV-cured adhesive. The ring demonstrates excellent temperature and vibration performance, and supports mass production with consistent product quality.
