The Fujikura FSM-20PM I Arc Fusion Splicer is a precision instrument engineered for automated splicing of polarization-maintaining and single-mode optical fibers. This controller unit delivers low-loss splices through integrated fiber gap setting, core/cladding alignment via advanced image processing, and automatic arc discharge. Dual PM alignment technologies and plasma zone fiber positioning ensure high-quality results in telecommunications and fiber optic systems where polarization integrity is critical.
