Standard Gyro Fiber
The #1 fiber for fiber optic gyroscopes
- High polarization extinction in coiled applications
- Ultra-short beat-length fibers offer the very best coil performance
- -55°C to +85°C in-coil operating range
- Tight coating diameter tolerance for high accuracy coil winding
- 80μm OD saves space and enhances lifetime
- Radiation tolerant variants for space applications
- High reliability in coiled applications
- High temperature coating variant available for downhole FOGs (fiber optic gyroscopes)
Typical Applications:
- FOGs (fiber optic gyroscopes)
- Current sensors
- Delay lines
