Ericsson FSU 925PM, 975PM & 995PM Fusion Splicer – Professional Repair, Precision Alignment & Full Recalibration
We specialize in repair, maintenance, and calibration services for the Ericsson FSU 925PM, 975PM, and 995PM Fusion Splicers—rugged and highly precise tools widely used in optical fiber network installations, lab environments, and field deployments. Known for their core-to-core alignment precision and long-term durability, these fusion splicers remain in use globally across telecom, aerospace, defense, and broadband infrastructure projects. Whether your splicer is showing arc issues, fiber mismatch, or display failure, our experienced team can restore it to factory-grade functionality with precision alignment and full system verification.
End-to-End Fusion Splicer Service Process
Complete Diagnostic Evaluation
We begin with a thorough inspection and performance test to identify:
Arc quality and arc count accuracy
Fiber core alignment (X/Y/Z axis movement)
Splice loss estimation and repeatability
V-groove cleanliness and tension settings
Display, keypad, and button responsiveness
Battery condition and charge cycles
Internal software/firmware version integrity
We test using single-mode and multimode fiber, simulate field splicing conditions, and inspect all internal systems to identify performance degradation or mechanical wear.
Common Issues We Repair
Misaligned fibers or poor splice quality
High splice loss or failed splice estimation
Worn or misfiring electrodes
Faulty motors (X, Y, Z alignment or fiber feed)
Arc power calibration failure
Dust or damage in V-groove or fiber clamps
Display screen issues (dim, flickering, or cracked LCD)
Keypad or touch control failure
Battery not charging or holding charge
Firmware bugs or boot failure
Precision Mechanical Repair & Cleaning
We perform mechanical adjustments and cleaning, including:
Replacing or reshaping electrodes
Cleaning and adjusting V-grooves, fiber clamps, and lens optics
Re-aligning fiber paths using high-resolution camera feedback
Calibrating arc discharge settings to match fiber type and environmental conditions
Motor & Sensor Testing
Each internal motor (X, Y, Z axis) is tested for travel precision, backlash, and response time. We replace worn actuators and recalibrate their range using OEM procedures.
Display & Interface Repair
We restore or replace display screens and front panel components as needed. All keypads, input buttons, and user interface systems are tested and repaired for full functionality.
Firmware Validation & Functional Tests
Post-repair, the unit is updated to the latest supported firmware (if available) and run through all functional self-tests. Splice loss, arc centering, and heat-shrink operations are validated.
Full Calibration & Verification
Every serviced Ericsson splicer undergoes:
Arc calibration and tuning based on fiber type
Splice loss measurement and repeatability checks
Fiber core alignment calibration using test fibers
Tension testing and mechanical integrity assessment
A final report with splice performance and system diagnostics is included with each unit.
