What Makes the Fujikura 40PM Fusion Splicer Special
Before diving into repair and calibration, let’s establish what the 40PM is and what users expect from it.
- Core alignment fusion splicer, designed for both single‐mode (SM) and multi‐mode (MM) fibers.
- Offers high splice performance even in challenging field conditions (dust, vibration).
- Quick splice times (often under 7 seconds for typical SM fibers), low splice loss.
- Status monitoring: loss estimates, heater/fiber alignment diagnostics, display of splice quality.
- Robust build: protective case, battery operation for field use.
Because of its demanding usage environment, even top models like the 40PM require periodic calibration, electrode replacement, alignment verification, and mechanical adjustments to maintain optimal splice quality and yield.
Why Calibration & Repair Are Crucial for the Fujikura 40PM
Here are the top reasons you should get your fusion splicer serviced regularly:
- Splice Loss Minimization
Small misalignments or degraded electrodes increase splice loss. For SM fiber, even 0.01 mm misplacement or dirt on the lens can degrade performance. Precise calibration keeps losses near OEM specs. - Consistency in Field Deployments
Inconsistency leads to rework, which costs time, materials, and reputation. Calibration ensures that every splice in the field meets standards. - Battery & Heating Element Efficiency
The warming (heat‐shrink sleeve or protection sleeve heater) and battery behavior drift over time—impacting splice protectiveness and on‐site throughput. - Safety & Reliability
Faulty clamps or misaligned fiber can cause fiber breakage or even safety hazards. Calibration ensures mechanical components function correctly. - Firmware & Display Integrity
Errors, crashes, or display misreadings may lead technicians to misjudge work. Repairing firmware issues and ensuring accurate displays matter. - Compliance & Warranty
For contractors under contracts or warranties, documented calibration and maintenance can be required. A calibration certificate from Aumictech carries weight.

Aumictech’s Calibration & Repair Process for Fujikura 40PM
Here’s an inside view into how Aumictech handles a full calibration/repair job for a 40PM—from drop-off to return:
Step 1: Intake & Diagnostic Evaluation
- Initial Performance Test: Run a series of test splices with known SM and MM fibers; measure loss.
- Visual Inspection: Check optics, clamps, clamps alignment, tool cleanliness, display condition, battery health.
- Log/Error Checks: Read stored error logs, check any firmware warnings.
- Electrical/Power Tests: Verify voltage regulation, battery charging behavior, heater element power draw.
Step 2: Repair & Component Replacement
Based on diagnosis:
- Swap electrodes with OEM equivalents if worn.
- Replace damaged optics or fiber lenses; clean all optical paths.
- Adjust or replace clamp assemblies.

- OEM Manufacturer: Before shipping a batch, customer used Aumictech’s preventive maintenance package (electrodes, firmware update, clamp calibration), ensuring first splice yield matched spec.
Maintenance Schedule & Best Practices
To get maximum life and reliability from your Fujikura 40PM, follow a maintenance schedule as part of normal operations:
| Interval | Task |
|---|---|
| Daily / Before Work | Clean fiber ends and optic lenses; inspect electrodes; check clamping surfaces; ensure heater is free of debris |
| Every 100-200 Splices | Inspect electrode wear; verify arc power does not fluctuate; wipe clamping mechanism grease or particle buildup |
| Monthly | Check firmware updates; monitor battery health and charge cycles; examine display and UI buttons for consistent response |
| Quarterly or Semiannual | Package regulatory and calibration number; send for calibration and alignment check; replace heater elements if drift detected |
| Annually | Full calibration and certification; replace worn mechanics like clamps or optical covers; deep cleaning and review of all electromechanical parts |
FAQs (Fusion Splicer – 40PM)
Q: How do I know if my Fujikura 40PM needs calibration or just cleaning?
A: If splice loss, alignment, or protection sleeve heating degrade noticeably, or if error codes appear, you likely need full calibration. If image quality is off but other functions are normal, cleaning optics/electrodes may suffice.
Q: How often should I replace electrodes?
A: It depends on usage, but after several hundred to a few thousand splices. Aumictech measures electrode erosion and recommends replacement when loss starts rising or arc becomes inconsistent.
Q: Will firmware updates improve performance?
A: Possibly. Sometimes firmware corrects alignment algorithms, user interface bugs, or power management issues. Aumictech tests and installs firmware only after confirming compatibility.
Q: Is calibration from Aumictech certified for contracts & tenders?
A: Yes. Our calibration is documented, traceable, and recognized in many industrial, telecom, and governmental quality systems.
Q: Can I get a loaner splicer while mine is being serviced?
A: Yes. Aumictech offers loaner or rental devices in many cases to reduce downtime.
