Fujikura FSM-100P, FSM-40PM, FSM-45PM & FSM-20PM Fusion Splicer – Expert Repair, Precision Alignment & Full Calibration
We offer professional repair, calibration, and alignment services for the Fujikura FSM-100P, FSM-40PM, FSM-45PM, and FSM-20PM Fusion Splicers—specialized tools designed for high-precision splicing of polarization-maintaining (PM) and specialty optical fibers. These splicers are widely used in fiber optic sensing, research labs, defense applications, and photonics manufacturing, where accuracy and core alignment are critical. Whether your splicer is failing to align fibers, producing high splice loss, or displaying arc errors, our team is equipped to restore it to full working condition with certified calibration and OEM-level accuracy.
Our Repair & Calibration Process
Comprehensive Diagnostics & Testing
Each Fujikura splicer is fully tested to assess:
X/Y/Z axis fiber positioning and alignment accuracy
Arc discharge stability and repeatability
Splice loss estimation and fiber core detection
Rotational alignment for PM fiber splicing
V-groove cleanliness, fiber clamp performance, and lens clarity
Display, keypad, and system boot-up functions
Battery condition and heater functionality (if applicable)
We use single-mode, polarization-maintaining (PM), and specialty fibers to test under realistic conditions, replicating splicing challenges in lab and production environments.
Common Problems We Repair
Inaccurate core alignment or rotation angle for PM fibers
High splice loss or unstable arc discharge
Worn or misaligned electrodes
Faulty X, Y, Z motors or sluggish fiber movement
Rotational axis (theta) malfunction or miscalibration
Boot-up errors, firmware freezes, or arc calibration failures
Damaged fiber clamps or V-grooves
Touchscreen or LCD display failure
Battery or charging system malfunction
Precision Mechanical Repair & Realignment
We service all mechanical and optical components, including:
Electrode cleaning or replacement
Cleaning and adjustment of V-grooves and fiber holders
Recalibration of X, Y, Z, and theta axes
Optical system cleaning for lenses and cameras
Motor Testing & Axis Calibration
All motorized stages (X/Y/Z/θ) are tested for range, precision, and consistency. We perform recalibration using live fiber feedback and factory-style alignment procedures to ensure ultra-low splice loss and correct core orientation.
User Interface & Display Repair
We repair or replace failing touchscreens, LCDs, and control keypads. Full system testing ensures seamless operation across menus, splice modes, and test procedures.
Firmware Validation & Functional Checks
After mechanical and electronic repairs, we run:
Arc calibration using factory protocols
Real splice tests on PM and SM fibers
Auto-check routines for motor travel and loss estimation
Software/firmware version checks and updates (if applicable)
NIST-Traceable Calibration
Post-repair, we perform a complete NIST-traceable calibration, including:
Arc power tuning and test splices
X/Y/Z/theta axis accuracy verification
Splice loss and rotational alignment repeatability tests
Full calibration report with before/after data
