The Fujikura FSM-30S is an automatic core alignment fusion splicer engineered for single-mode, dispersion-shifted, and multimode optical fibers across telecommunications and field deployment. It employs Profile Alignment System (PAS) technology for direct core monitoring, delivering ultra-low splice loss with accurate loss estimation independent of fiber age or quality. The splicer automatically aligns fiber cores, inspects cleave geometry, and applies eccentricity correction to maintain precision in demanding environments.
