Coherent elliptical clad PM Gyroscope fibers have high birefringence and are designed for gyroscope and sensor applications. These fibers feature good bending performance and are optimized for either 850 nm or 1300 nm wavelength operation. The 850 nm optimized fiber has a 40 µm clad diameter and the 1300 nm optimized fiber has an 80 µm clad diameter. Both are ideally suited for applications requiring a small form factor.
