Fujikura FSM-20RSII12 ARC Fusion Splicer

The Fujikura FSM-20RSII12 ARC Fusion Splicer is a field-deployable instrument for splicing single-mode, multi-mode, and ribbon optical fibers up to 12 fibers. It delivers consistent low-loss connections through automated splicing and heating cycles, Profile Alignment System (PAS) core/cladding alignment, and real-time fiber inspection via LCD monitor. Splice loss estimation, arc auto-calibration, and environmental compensation ensure reliability across telecom and datacom deployment scenarios.
