The Fibercore PM Gyro HB800G/013 is a polarization-maintaining optical fiber engineered for high-precision fiber optic gyroscopes. This 250-meter spool delivers exceptional birefringence stability and polarization extinction ratio performance across demanding aerospace, navigation, and defense applications. The /013 variant features a reduced 135 ± 2 µm coating diameter, optimizing coil winding density while maintaining polarization integrity from -55°C to +85°C operating range.
