Nufern's PANDA-style PM Gyroscope fibers have extremely high birefringence and exceptionally tight dimensional specifications, critical for manufacturing high precision, high-performance gyro-coils. These fibers feature a reduced coating diameter to make smaller gyro coils possible. High consistency and extreme end-to-end control of optical properties provide particular advantage in this application by reducing fiber generated signal artifacts. The intrinsically high level of radiation resistance allows this family to operate for extended periods of time on low earth orbits, near and deep space, and in applications where risk of exposure to man-made radiation is great. The Panda-style configuration is preferred over bow-tie or elliptical clad designs because of its advantages in process scalability (for its cost impact) and product uniformity. These fibers are available for operation at 850, 1300 and 1550 nm wavelengths.
