The Fujikura FSM-40S is a profile alignment fusion splicer designed for precision optical fiber joining in field and laboratory environments. It delivers consistent low-loss splices across single-mode and multi-mode fiber types using automated core and cladding alignment, high-resolution imaging, and integrated heat treatment. Typical splice loss is 0.02 dB for single-mode and 0.01 dB for multi-mode fibers, with splice completion in approximately 9 seconds and heat-shrink protection in 25 seconds.
