Product Description

1. Introduction

Our coupled single-mode fiber is a special single-mode fiber product specially designed and developed for the application of optical devices. This series of optic fiber preform is prepared with in-tube chemical vapor deposition process. By combining with reasonable waveguide design, the optic fiber has the advantages of low hydroxyl group, good bending performance, good optical uniformity and so on. The double-layer UV-curable acrylate coating makes the optic fiber have the characteristics of high tensile strength, long-term fatigue resistance and so on. This series of optic fibers are widely used in optic fiber communication devices and optic fiber sensing devices.
