Fujikura ELCT2-12 Fusion Splicer Replacement Electrodes

Fujikura ELCT2-12 Fusion Splicer Replacement Electrodes

Fujikura ELCT2-12 Fusion Splicer Replacement Electrodes are consumable replacement components for compatible Fujikura compact 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 ELCT2-12 electrode pair is compatible with selected Fujikura FSM-11S, FSM-11R, FSM-12S, FSM-12R, 21S, and 22S fusion splicers. Compatibility should always be verified using the complete splicer model and existing electrode designation before ordering.

Matched Replacement Electrodes for Fujikura Fusion Splicers

• Matched electrode pair: Includes two replacement electrodes for balanced installation.
• Compact splicer compatibility: Designed for selected Fujikura compact field fusion splicers.
• Controlled arc discharge: Proper installation helps maintain stable and repeatable fiber heating.
• Routine maintenance component: Electrode inspection and replacement are part of preventive fusion splicer maintenance.
• Model-specific design: Compatibility must be confirmed using the complete Fujikura splicer model.
• Arc calibration required: Electrode stabilization and arc calibration should be completed after installation.

Compatible Fujikura Fusion Splicers

The Fujikura ELCT2-12 electrode pair is commonly specified for selected models in the following compact fusion splicer families:

• Fujikura FSM-11S
• Fujikura FSM-11R
• Fujikura FSM-12S
• Fujikura FSM-12R
• Fujikura 21S
• Fujikura 22S

Confirm the complete model number, equipment generation, regional configuration, and existing electrode marking before installing replacement electrodes.

Why Electrode Condition Matters

Fusion splicer electrodes operate under repeated high-voltage arc discharges. Each splice contributes to gradual electrode-tip wear. Fiber type, splice mode, arc power, electrode spacing, environmental conditions, and equipment cleanliness can affect electrode condition 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 electrode counter provides useful maintenance guidance, but splice count should not be the only consideration. Physical electrode condition, calibration results, fusion performance, and the applicable Fujikura maintenance instructions should also be reviewed.

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 one new electrode with one worn electrode may create uneven arc geometry and inconsistent fiber heating. Confirm that both electrodes are properly 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 stripped and cleaved fibers during calibration.

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

Signs That Electrode Maintenance May Be Required

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