Fujikura FSM-70S SM MM Core Alignment Fiber Fusion Splicer

The Fujikura FSM-70S is a core alignment fusion splicer for single-mode and multimode optical fibers across field and laboratory environments. It delivers exceptional splice loss performance—0.02 dB for SM fiber and 0.01 dB for MM fiber—with splicing times as fast as 6 seconds in ULTRA FAST mode. The clamshell tube heater automates the protection sleeve process in 9–14 seconds depending on configuration. Rugged construction withstands shock, dust, and moisture in harsh conditions.
