When you depend on high-precision PM fiber splicing, even the smallest error can compromise system performance, signal integrity, or alignment stability. That’s why Aumictech offers specialized repair and calibration services for the Fujikura FSM-45PM Fusion Splicer, one of the industry’s most trusted tools for polarization-maintaining fiber splicing.
Whether your FSM-45PM is showing arc discharge errors, misaligning fibers, or simply in need of recalibration, we provide end-to-end diagnostics, repairs, and NIST-traceable calibration to ensure your tool performs like new — with minimal downtime and maximum accuracy.
About the Fujikura FSM-45PM Fusion Splicer
The Fujikura FSM-45PM is a compact, core-alignment fusion splicer designed specifically for PM (Polarization-Maintaining) fibers, offering unmatched repeatability and low splice loss in the field or lab. It’s known for:
- High-resolution three-axis core alignment
- Accurate rotational splicing for PM fibers
- Auto-arc calibration and environmental compensation
- Efficient, field-ready design with battery operation
- User-friendly interface with real-time feedback
Often used in fiber optic gyro manufacturing, quantum research, DWDM applications, and PM fiber sensor installations, the 45PM is built for performance — but requires routine maintenance and periodic calibration to keep operating at factory standards.
Common Problems with the FSM-45PM – What We Fix
The FSM-45PM contains precision optics, stepper motors, sensors, and arc systems that can degrade over time due to environmental exposure, fiber debris, or high usage. At Aumictech, we diagnose and repair issues such as:
🔧 Arc Discharge Inconsistency
- Symptoms: “Arc Error,” burnt splices, inconsistent loss values
- Solution: Electrode inspection/replacement, arc power calibration, and internal arc board diagnostics
🔧 PM Fiber Rotation Misalignment
- Symptoms: Splice loss varies, rotational alignment failure
- Solution: Realignment of fiber rotation mechanism, motor calibration, and internal optical checks
🔧 Image Display or Camera Malfunction
- Symptoms: Blurry fiber view, core not detected, black screen
- Solution: Lens cleaning, CCD camera alignment, or replacement of camera assembly
🔧 Touchscreen, UI, or Firmware Issues
- Symptoms: Frozen menus, failed startup, display glitches
- Solution: Firmware reset, software upgrade, replacement of internal PCB or UI board
🔧 Faulty Heater or Clamp
- Symptoms: Sleeves not shrinking properly, clamp error
- Solution: Heater testing, thermal profile calibration, clamp motor servicing
🔧 Battery, Charging Port, or Power Issues
- Symptoms: Unit fails to charge, runs only on AC, short battery life
- Solution: Battery diagnostics, port replacement, charging circuit repair
All repaired units undergo post-repair stress testing, test splices with SM and PM fibers, and are returned fully cleaned and calibrated.
Calibration Services for the FSM-45PM
Calibration is essential to ensure your FSM-45PM maintains:
- Splice repeatability
- Accurate core and cladding alignment
- Consistent arc discharge
- Low insertion loss across splices
- Proper rotational alignment of PM fibers
At Aumictech, we offer NIST-traceable calibration services that include:
- ✔️ Arc power calibration and stabilization
- ✔️ X/Y/Z motor precision movement testing
- ✔️ Rotational splicing alignment verification
- ✔️ Core detection accuracy test (for SM and PM fibers)
- ✔️ Heater timing and temperature consistency check
- ✔️ CCD camera alignment and image sharpness adjustment
- ✔️ Software validation and UI responsiveness
- ✔️ Environmental sensor and auto-compensation checks
We simulate real-world fiber splicing scenarios and test the FSM-45PM with various PM1550 and PM980 fibers to ensure accurate alignment and minimal loss, then deliver a calibration certificate with:
- Splice loss reports
- Arc count and condition
- Date of service and next calibration due date
- Technician validation and service summary
