80µm Diameter Operating at 1310nm/1550nm Elliptically clad polarization-maintaining fiber

Elliptically clad polarization-maintaining fiber is a specially designed, stress-type polarization-maintaining fiber. Its structural characteristics provide excellent polarization-maintaining performance. Furthermore, compared to bowtie-type polarization-maintaining fiber, it reduces the manufacturing process complexity and maintains good geometric consistency. Fibercloud's elliptically clad polarization-maintaining fiber optimizes the fiber's axial uniformity. By utilizing proprietary internal and external coating materials, it exhibits excellent temperature stability and birefringence performance, making it widely applicable in fiber optic gyroscopes, current transformers, and other polarizationdependent devices.
