Fujikura FSM-30PF SM MM High Strength Fusion Splicer

The Fujikura FSM-30PF is a high-strength fusion splicer for single-mode and multimode optical fibers, engineered to deliver low-loss splices in factory and field environments. Using Profile Alignment System (PAS) technology with computer-controlled CCD imaging, the FSM-30PF achieves automatic core-to-core alignment for SM fibers and cladding-to-cladding alignment for MM fibers. Typical splice loss reaches 0.02 dB for identical SM fibers (ITU-T G.652) and 0.01 dB for identical MM fibers (ITU-T G.651), with advanced arc discharge parameters and wide arc profiles enabling splicing of dissimilar fiber types. The splicer supports short cleaved length splicing (3 mm to 6 mm) with fiber coating clamped for tensile strength up to approximately 30 N, or standard splicing at 13 mm to 19 mm with cladding clamped.
