Fujikura ELCT1-25 Fusion Splicer Replacement Electrodes

Fujikura ELCT1-25 Fusion Splicer Replacement Electrodes

Fujikura ELCT1-25 Fusion Splicer Replacement Electrodes are consumable components for compatible Fujikura specialty fiber fusion splicers. Supplied as a matched pair, the electrodes generate the controlled electrical arc used to heat and fuse prepared optical fiber end-faces.

The ELCT1-25 is designed for selected Fujikura FSM-20, FSM-30, FSM-40, and FSM-45 specialty fusion splicers. Compatibility should always be verified using the complete splicer model, model suffix, and existing electrode designation before ordering.

Matched Replacement Electrodes for Specialty Fusion Splicers

• Matched electrode pair: Includes an anode and cathode for balanced installation.
• Specialty splicer compatibility: Supports selected Fujikura FSM-20, FSM-30, FSM-40, and FSM-45 platforms.
• Controlled arc discharge: Correct installation helps maintain stable and repeatable fiber heating.
• Model-specific design: Electrode geometry and compatibility must match the complete fusion splicer model.
• Routine maintenance component: Electrode inspection and replacement form part of preventive fusion splicer maintenance.
• Arc calibration required: Complete the applicable stabilization and arc-calibration procedures after installation.

Compatible Fujikura Fusion Splicers

The Fujikura ELCT1-25 electrode pair is specified for selected models in the following specialty fusion splicer families:

• Fujikura FSM-20C
• Fujikura FSM-20CS
• Fujikura FSM-20CSII
• Fujikura FSM-20PM
• Fujikura FSM-20PMII
• Fujikura FSM-30S
• Fujikura FSM-40S
• Fujikura FSM-40F
• Fujikura FSM-40PM
• Fujikura FSM-45F
• Fujikura FSM-45PM

Compatibility may vary by equipment generation and configuration. Confirm the complete model number and installed electrode type before replacing the electrodes.

Why Electrode Condition Matters

Fusion splicer electrodes operate under repeated high-voltage arc discharges. Each fusion cycle gradually wears the electrode tips. Arc power, electrode gap, fiber dimensions, processing mode, environmental conditions, and fusion-chamber cleanliness can affect electrode performance and service life.

Worn or contaminated electrodes may contribute to unstable arc discharge, unsuccessful arc calibration, inconsistent fiber heating, unusual splice appearance, recurring fusion errors, or changes in estimated splice loss.

The fusion splicer’s arc counter provides useful maintenance guidance, but electrode condition and actual fusion performance should also be considered. Fujikura documentation for this electrode generation recommends replacing the pair after approximately 1,000 arc discharges.

Electrode Replacement and Arc Calibration

Turn off the fusion splicer before removing or installing electrodes. Follow the applicable Fujikura operating and maintenance instructions, and avoid touching the pointed electrode tips with fingers or tools.

Replace both electrodes together as a matched pair. Combining a new electrode with a worn electrode may create uneven arc geometry and inconsistent fiber heating. Confirm that both electrodes are correctly seated and secured before operating the fusion splicer.

After installation, complete the electrode stabilization and arc-calibration procedures specified for the splicer. Use clean, correctly prepared fibers during calibration.

Electrode replacement is also an appropriate time to inspect and clean the V-grooves, fiber clamps, mirrors, objective lenses, electrode holders, and surrounding fusion chamber.

Signs That Electrode Maintenance May Be Required

• Repeated arc-calibration failures
• Unstable or visibly inconsistent fusion arcs
• Visible contamination, pitting, or damage on the electrode tips
• Unexpected changes in estimated splice loss
• Inconsistent fiber heating or unusual splice appearance
• Recurring fusion errors after fiber preparation has been verified
• Electrode count reaching the replacement interval specified for the splicer

Electrode Selection Guidance

Select ELCT1-25 only when specified for the complete Fujikura fusion splicer model. Some large-diameter or later-generation specialty configurations may require ELCT2-25, ELCT3-25 STD, or ELCT3-25-LDF electrodes instead.

Provide the complete model number, including any F, PM, LDF, or Plus suffix, when requesting replacement electrodes.
