Panda PMF for FOG Waveguide
1. Introduction
Panda polarization-maintaining fiber for FOG waveguide manufactured by YOEC can be used in the field of fiber optic gyroscope and other polarization-related devices, which is optimized for device requirements, mainly for geometric symmetry & grind-ability. While maintaining the polarization property of the fiber, it has the ability to grind. It is a kind of polarization-maintaining fiber that can be wound or ground.
