Elliptical-Core Polarization-Maintaining Fiber

Elliptical-Core Polarization-Maintaining Fiber

The elliptical-core polarization-maintaining fiber offers excellent temperature stability and birefringence performance, making it suitable for a wide range of applications including fiber optic gyroscopes, current transformers, and other polarization-sensitive devices. By optimizing the fiber core and cladding structure, this elliptical-core fiber achieves improved uniformity and birefringence. As a geometric-birefringence type of polarization‑maintaining fiber, it is less affected by ambient temperature variations and provides better temperature stability.

Product features：Excellent attenuation and bending performance；Good geometric uniformity；Excellent reliability；Excellent temperature performance

Part Number：MP‑ECF13‑125‑025

Application area：Fiber optic gyroscopes | Fiber optic current transformers | Fiber lasers and amplifiers
