The SCF-UN-30/250-11 single-clad passive fiber is designed for manufacturing passive components that match Coractive’s DCF-YB-30/250P-FAC active fiber. Its single cladding allows mode filtering to achieve effective quasi-single-mode operation. These components are part of pulsed fiber lasers designed for industrial applications.
