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
