The Fujikura FSM-18S is a single-fiber arc fusion splicer engineered for field deployment in FTTx, PON, and access network installations. It combines fixed V-groove cladding alignment with dual CMOS camera imaging to deliver consistent low-loss splices across multiple fiber types. The unit’s rugged construction resists shock, dust, and moisture, while its compact form factor (136 mm × 161 mm × 143 mm) suits mobile and confined workspace operation.
