The Fujikura FSM-11S is a portable fusion splicer engineered for both single-mode and multimode optical fibers in field and access network environments. Dual-camera fiber inspection with automatic arc calibration delivers consistent splice quality across 40 splicing modes. The compact 640 g chassis (without battery) integrates a 3.5-inch color LCD monitor with 130x magnification, cladding-alignment V-grooves, and rapid 11-second splice cycles for standard SM fiber. Data logging stores the last 2,000 splice results internally via USB interface.
