Product Details
Bow-tie Polarization-maintaining Fiber
1. Introduction
Bow-tie polarization-maintaining fiber manufactured by YOEC is mainly used in the field of fiber optic gyroscope & current transformer, with the excellent temperature stability & birefringence performance.
YOEC adopts MCVD process to produce bow-tie polarization-maintaining fibers, which optimizes the structure of fiber core & stress zone, improves the fiber symmetry & consistency, and makes better polarization performance & temperature stability.
