Fujikura FSM-17S SM MM Fiber Optic Fusion Splicer

The Fujikura FSM-17S is a single-fiber fusion splicer for both single-mode and multimode optical fibers. It delivers low-loss splices in approximately 9 seconds with automated fiber alignment, 180x magnification viewing, and integrated heating in a compact, field-deployable package. Operating from -10°C to +50°C and capable of 120 splice-heat cycles per charge, the FSM-17S supports SM, MM, DSF, and NZDSF fibers with cladding diameters from 80 to 150 µm.
