Matching passive fibers – Single Clad / Double Clad

YOFC single-clad and double-clad passive fibers are used in fiber lasers in industrial and medical fields, as well as related optical devices.

This series of optical fibers precisely match the active double-clad fibers and significantly improves the splicing efficiency with the double-clad active optical fiber. Multimode fibers with large core diameters and high numerical apertures could be used for pigtailing output of pump diodes or high power fiber lasers.
