Ericsson FSU 975FA & 995FA Fusion Splicer – Expert Repair, Precision Alignment & Arc Calibration
We provide professional repair, maintenance, and calibration services for the Ericsson FSU 975FA and 995FA Fusion Splicers—core alignment fusion splicers trusted worldwide for high-precision optical fiber splicing. These fully automatic (FA) models are known for their speed, accuracy, and repeatable low-loss splices, making them ideal for high-volume telecom deployments, fiber network maintenance, and lab environments. If your splicer is failing to align, showing splice loss errors, or experiencing arc issues, our expert technicians are equipped to restore it to full operational condition with OEM-level accuracy.
Our Fusion Splicer Repair Process
Comprehensive Evaluation & Testing
Each Ericsson FSU 975FA or 995FA unit is inspected and tested in detail to evaluate:
Arc power stability and arc count calibration
Fiber alignment (X/Y/Z axes) and core detection performance
Splice loss estimation accuracy and repeatability
Condition of V-grooves, fiber clamps, and electrodes
Motor responsiveness and alignment travel range
Battery health and charge cycle status
Display screen clarity and interface responsiveness
Communication ports and internal software stability
We test both single-mode and multimode fibers, under simulated field conditions, to identify real-world issues during splice cycles.
Common Issues We Repair
High splice loss or alignment failure
No arc or irregular arc discharge
Misalignment or sluggish X/Y motor movement
Worn or misaligned electrodes
Dirty, cracked, or misaligned V-grooves and fiber holders
Boot-up errors or frozen interface
LCD/display screen dimming or failure
Keypad or button malfunctions
Battery not charging or unit shutting off unexpectedly
Internal software glitches or firmware mismatch
Precision Mechanical Repair & Cleaning
We restore mechanical components with care, including:
Electrode cleaning or replacement
V-groove cleaning, realignment, and tension adjustment
Fiber holder and clamp inspection and reconditioning
Full disassembly and cleaning of internal optics and lenses
Motor & Axis Calibration
All internal motors (X, Y, Z) are tested and calibrated for precision movement and core alignment. We measure travel accuracy, backlash, and positioning, replacing faulty motors or sensors as needed.
Display & Control Interface Repair
Display screens, control panels, and keypads are inspected, repaired, or replaced to ensure a fully functional user interface and splicing workflow.
Firmware, Settings & Functional Verification
Units are reset, updated (if applicable), and run through full diagnostics:
Arc test
Loss estimation
Splice simulation
Heating cycle (if heater is integrated)
NIST-Traceable Calibration & Splice Testing
After repairs, we conduct NIST-traceable calibration, including:
Arc calibration tailored to fiber type
Alignment repeatability testing
Splice loss and signal integrity checks using industry test fibers
Environmental and thermal stability tests
We provide a performance report and calibration certificate with before-and-after data.
