Fujikura ELCT2-16B Fusion Splicer Replacement Electrodes

Fujikura ELCT2-16B Fusion Splicer Replacement Electrodes

Fujikura ELCT2-16B Fusion Splicer Replacement Electrodes are consumable replacement components for compatible Fujikura field and ribbon fusion splicers. Supplied as a matched pair, the electrodes generate the controlled electrical arc used to heat and fuse prepared optical fiber end-faces.

Repeated fusion cycles gradually wear the electrode tips and may allow deposits to accumulate in the fusion chamber. Worn, contaminated, damaged, or incorrectly installed electrodes can affect arc stability, arc calibration, fiber heating, estimated splice loss, and overall splice consistency.

The ELCT2-16B electrode pair is commonly specified for selected Fujikura 31S, 41S, 45S, 90S, and 90R Series fusion splicers. Compatibility should always be verified using the complete splicer model and the marking on the existing electrodes before ordering.

Matched Replacement Electrodes for Fujikura Fusion Splicers

• Matched electrode pair: Includes two replacement electrodes for balanced installation.
• Field and ribbon splicer compatibility: Supports selected Fujikura single-fiber and mass-fusion splicers.
• Controlled arc discharge: Correct installation helps maintain stable and repeatable fiber heating.
• Tool-free replacement: Compatible splicers allow the electrodes to be replaced without specialized tools.
• Extended service life: Electrode life is approximately 5,000 to 6,000 splices, depending on the splicer and operating conditions.
• Preventive maintenance component: Electrode inspection and replacement form part of routine fusion splicer maintenance.
• Arc calibration required: Complete the applicable electrode stabilization and arc-calibration procedures after installation.

Compatible Fujikura Fusion Splicers

The Fujikura ELCT2-16B electrode pair is commonly specified for selected models in the following fusion splicer families:

• Fujikura 31S
• Fujikura 41S
• Fujikura 45S
• Fujikura 88S and 88S+
• Fujikura 88R
• Fujikura 90S and 90S+
• Fujikura 90R

This compatibility list is a selection guide. Confirm the complete splicer model, equipment generation, and existing electrode marking before installing replacement electrodes.

ELCT2-16 and ELCT2-16B Are Different Models

The ELCT2-16B is a later electrode model used with selected Fujikura 31S, 41S, 45S, 88 Series, and 90 Series fusion splicers.

The earlier ELCT2-16, without the B suffix, is associated with selected legacy FSM-16 and FSM-30 Series fusion splicers. These electrode models should not be treated as interchangeable.

Always include the complete suffix when ordering. The correct product designation for this page is ELCT2-16B.

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 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 electrode counter provides useful maintenance guidance, but splice count should not be the only consideration. Physical electrode condition, arc-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 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 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

Electrode Selection Guidance

Select ELCT2-16B only when this complete electrode designation is specified for the fusion splicer. Do not substitute the earlier ELCT2-16 electrode model.

For Fujikura 100S and 100R fusion splicers, ELCT2-16C electrodes are generally required instead. For older FSM-50, FSM-60, FSM-70, and FSM-80 Series models, ELCT2-20A electrodes may be required.
