Product Description

1. Introduction

Our elliptical core polarization-maintaining fiber has excellent temperature stability and birefringence performance, so it can be widely used in fiber optic gyroscope, current transformer and other polarization related devices. The YOEC's elliptical core fiber improves the uniformity and birefringence of the fiber by improving the elliptical core structure and optimizing the core and cladding structure of the fiber. The elliptical core polarization-maintaining fiber belongs to the geometric birefringent polarization-maintaining fiber, which is less affected by ambient temperature and has better temperature stability.
