At Aumictech, we specialize in repair, maintenance, and calibration services for Fujikura FSM-40PM Fusion Splicers, a trusted tool in the fiber optic world for aligning and splicing polarization-maintaining (PM) fibers. Our team combines deep technical knowledge with real-world field experience to bring your FSM-40PM back to peak performance — whether it’s displaying arc errors, alignment issues, or failing to boot.
We understand that fusion splicers are the backbone of your fiber deployment or manufacturing operation, and when they fail or fall out of calibration, your productivity and signal integrity suffer. That’s why Aumictech provides comprehensive, certified service that restores your tool to factory-level performance — or better.
About the Fujikura FSM-40PM Fusion Splicer
The FSM-40PM is a high-precision fusion splicer engineered for polarization-maintaining (PM) fiber splicing — commonly used in telecom networks, sensors, military systems, and advanced photonic applications. Despite being a legacy unit, the 40PM is still relied upon in labs and field operations for its:
- Three-axis alignment capability
- Rotational splicing for PM fibers
- High-resolution core alignment system
- Built-in heater and LCD interface
- Compact and portable design
As robust as it is, the FSM-40PM includes delicate motors, cameras, arc systems, and processors that degrade with use, dust, and environmental exposure. Without proper maintenance, splicing quality deteriorates, leading to higher insertion loss and repeatability errors.
Common Issues We Repair on the FSM-40PM
Our technicians at Aumictech are trained to repair Fujikura PM splicers down to the component level. Here are the most common issues we handle:
🔧 Arc Discharge Errors / Inconsistent Arcing
- Often due to worn electrodes, arc power drift, or internal circuitry degradation
- We clean or replace electrodes, recalibrate arc power, and restore precision
🔧 Alignment Failure / Core Detection Problems
- Caused by dusty lenses, misaligned CCD cameras, or degraded motors
- We clean optical paths, realign motors, and recalibrate the alignment algorithm
🔧 Failed Heater or Lid Mechanism
- Affects sleeve shrinking and fiber protection processes
- We replace heating elements and test timing and temperature controls
🔧 Display or Booting Issues
- Aging LCD screens or firmware corruption can prevent proper operation
- We replace screens, inspect internal connections, and update firmware if needed
🔧 Poor Splice Loss Results
- Could be linked to environmental sensors, calibration drift, or worn V-grooves
- We inspect clamping mechanisms, clean grooves, and restore fiber positioning accuracy
🔧 Battery, Charging, or Power Supply Faults
- For portable use, charging systems must function reliably
- We test and replace battery packs, ports, and AC/DC converters
Each unit is tested under real-world splicing conditions using both standard single-mode and polarization-maintaining fiber to ensure optimal performance post-repair.
Full Calibration Services for FSM-40PM
At Aumictech, calibration goes beyond visual alignment. We offer precise, instrument-level recalibration of all the systems that make a Fujikura splicer accurate and repeatable, including:
- Arc power calibration
- Camera and lens alignment
- Cladding and core detection accuracy
- Splice loss estimation testing
- Heater temperature and timing adjustment
- X/Y axis motor response verification
- Environmental compensation sensor testing
- Tension test function validation
Calibration includes NIST-traceable references where applicable, and we issue a full calibration certificate that includes:
- Calibration date and next due date
- Arc count and maintenance indicators
- Fiber types used during testing
- Splice loss data (pre and post)
- Technician sign-off and comments
