This unit
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.

Fujikura FSM-40S — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Fujikura FSM-40S. Calibration covers arc calibration (arc power and duration), V-groove alignment verification, cleave angle detection accuracy, splice loss estimation accuracy, and heating oven temperature calibration. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Fujikura FSM-40S faults: electrode wear, V-groove contamination or chipping, motor alignment drift, high arc voltage errors. Common repairs include electrode replacement (typically every 2,000-3,000 arcs), V-groove cleaning or replacement, motor and actuator alignment, and camera/CCD replacement. Fujikura FSM and Sumitomo Type series parts are stocked.
