Free Standing PM Fiber Coil F50 for Closed-loop Φ120 Fiber Optic Gyroscope with Quadrupole Winding
Our φ50 low-precision (mid-accuracy) fiber coil is engineered specifically for closed-loop FOG systems. Utilizing 135µm thin-diameter fiber technology, this coil delivers superior winding density and exceptional temperature performance. The design minimizes crosstalk and bias drift, ensuring reliable gyroscope heading maintenance under thermal stress conditions.
Primarily designed for closed-loop fiber optic gyroscopes with approximately 50mm diameter requirements.
- Multi-pole symmetric winding method for optimal performance
- 135µm thin diameter optical fibers with UV-cured adhesive
- Excellent temperature and vibration performance characteristics
- Mass production capability with consistent product quality
- Superior winding density for enhanced system reliability
