High-Photosensitivity Fibers

Fiber Bragg Gratings (FBGs) are at the heart of the DWDM revolution, enabling cutting-edge telecommunications performance. Thanks to an innovative germania and boron co-doped composition, Fibercore’s PS series fibers allow the writing of high-reflectivity gratings without the need for hydrogen loading. Designed for seamless integration, these fibers feature an optimized mode field diameter, ensuring low-loss splicing with standard telecom or pigtailing fibers. Speed up your FBG manufacturing with high-photosensitivity fibers designed for performance and effortless integration.
