80/125µm Diameter Operating at 1310nm/1550nm Bowtie Polarization-Maintaining Fiber

Bowtie polarization-maintaining fiber is a specially designed stress-type polarization-maintaining fiber with excellent polarization-maintaining
performance due to its structural characteristics. Fibercloud's bowtie polarization-maintaining fiber optimizes axial uniformity and batch consistency, and exhibits excellent temperature stability and birefringence performance. It can be widely used in fiber optic gyroscopes, current transformers, and other polarization-dependent devices.
