Fiber Optic Gyro (FOG) Coils Sensors

The General Photonics FC series of frameless fiber coils are available with lengths of 50 meters to 5 kilometers and diameters of 15 millimeters to 120 millimeters. The frameless coils are constructed with proprietary potting adhesives to ensure reliability. Coil patterns available include quadrupole and octupole patterns that minimize the Shupe effect and consequent degradation of Sagnac gyros over temperature. The FC series is available with complete test data including polarization cross-talk vs. distance for PM fiber coils; and PDL vs. temperature and PMD vs. temperature for SM fiber coils.
