Service & Repair of Ericsson FSU 995FA Fusion Splicer

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.
