The SCF-UN-8/125-14 single-clad passive fiber has been designed to match doped fibers such as Coractive’s DCF-EY-6/128 and DCF-EY-10/128H. Its single cladding allows mode filtering to achieve effective quasi-single-mode operation. Moreover, it can be used for manufacturing passive components used in the design of fiber lasers and amplifiers.
