Fujikura Fusion Splicer Replacement Electrodes

Fujikura Fusion Splicer Replacement Electrodes

Fujikura Fusion Splicer Replacement Electrodes are consumable components designed for compatible Fujikura field, ribbon, and specialty fiber fusion splicers. Installed as a matched pair, the electrodes create the controlled electrical arc used to heat and fuse prepared optical fiber end-faces.

Electrode condition is important for maintaining stable arc discharge and consistent fiber heating. Repeated fusion cycles gradually wear the electrode tips and can allow deposits to accumulate in the fusion chamber. Worn, contaminated, damaged, or incorrectly installed electrodes may affect arc calibration, estimated splice loss, fusion consistency, and overall splice quality.

Fujikura produces several electrode models for different fusion-splicer platforms. Standard field-splicer electrodes, ribbon-splicer electrodes, ARCMaster specialty electrodes, and large-diameter fiber electrodes are not necessarily interchangeable. Always confirm the complete fusion-splicer model and required electrode part number before ordering.

Replacement Electrodes for Fujikura Fusion Splicers

Fujikura electrodes are designed to match the mounting arrangement, electrode geometry, spacing, and arc requirements of compatible splicers. Replacing worn electrodes with the correct matched pair helps restore the intended discharge characteristics of the fusion system.

• Matched electrode pairs: Replacement electrodes are normally supplied as a pair for balanced installation on both sides of the fusion arc.
• Model-specific compatibility: The appropriate electrode is determined by the complete Fujikura fusion-splicer model.
• Field-splicer options: Selected electrode models support compatible Fujikura single-fiber field splicers.
• Ribbon-splicer options: Replacement electrodes are available for compatible Fujikura mass and ribbon fusion splicers.
• Specialty-splicer options: ELCT2-25 and ELCT3-25 Series electrodes support selected Fujikura ARCMaster platforms.
• Large-diameter fiber option: ELCT3-25-LDF electrodes are intended for supported large-diameter fiber processing configurations.
• Preventive maintenance component: Electrode inspection and replacement form part of routine fusion-splicer maintenance.
• Professional service support: Electrode replacement can be combined with cleaning, inspection, arc calibration, and functional testing.

Why Fusion Splicer Electrode Condition Matters

Fusion splicer electrodes operate under repeated high-voltage arc discharges. Each splice contributes to gradual tip wear. The actual electrode service life depends on the splicer model, fiber type, splice mode, arc power, electrode gap, operating environment, cleanliness, and maintenance practices.

As the electrode tips wear, the shape and stability of the fusion arc may change. This can contribute to inconsistent fiber heating, failed arc calibration, unusual splice appearance, increased estimated splice loss, or recurring fusion errors.

The splicer’s electrode counter provides useful maintenance guidance, but splice count should not be the only consideration. The physical electrode condition, arc-calibration results, fusion performance, and applicable Fujikura maintenance instructions should also be reviewed.

Field and Ribbon Fusion Splicer Electrodes

The ELCT2-16B electrode pair, AFL No. S017103, is used with selected Fujikura 90 Series, 31/41S, and 35/45S fusion splicers. Compatibility must be verified using the complete splicer model because requirements can vary between product generations.

The ELCT2-16C electrode pair, AFL No. S018669, is specified for compatible Fujikura 100S and 100R fusion splicers. It should not be replaced with another ELCT model unless compatibility has been confirmed.

Legacy Fujikura fusion splicers and models not listed on this page may require another electrode type. Provide the complete model number and current electrode part number when requesting replacements.

ARCMaster and Specialty Fiber Electrodes

The ELCT2-25 electrode pair is intended for selected Fujikura ARCMaster FSM-100M and FSM-100P specialty fusion splicers. These systems use advanced plasma-zone control for specialty optical fibers and require electrodes matched to the arc-processing platform.

The ELCT3-25 is the standard electrode configuration for selected FSM-100M+ and FSM-100P+ ARCMaster systems. The ELCT3-25-LDF is intended for supported large-diameter fiber applications requiring a wider or differently controlled plasma zone.

Standard and large-diameter fiber electrodes should not be substituted without confirming the ARCMaster model, fiber diameter, electrode spacing, processing method, and required operating procedure.

Electrode Replacement and Arc Calibration

Before replacing electrodes, turn off the fusion splicer and follow the applicable Fujikura operating and maintenance instructions. Avoid touching the electrode tips because oil, dirt, or physical damage can affect arc performance.

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 splicer.

After installation, complete the electrode stabilization and arc-calibration procedures required for the splicer. The exact process varies by model and should be performed using clean, properly prepared fiber under suitable environmental conditions.

Electrode replacement is also an appropriate time to inspect and clean the V-grooves, fiber clamps, objective lenses, mirrors, wind protector, and fusion chamber. Contamination in these areas may cause alignment or splice-performance problems that resemble electrode wear.

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 and V-groove cleanliness have been verified
• Electrode count reaching the replacement interval specified for the splicer

Fujikura Electrode Selection Guide

Select ELCT2-16B only for a compatible Fujikura splicer specified for AFL No. S017103. This includes selected 90 Series, 31/41S, and 35/45S fusion splicers.

Select ELCT2-16C for compatible Fujikura 100S and 100R fusion splicers. Confirm the complete equipment model before ordering.

Select ELCT2-25 for compatible FSM-100M and FSM-100P ARCMaster specialty systems. For FSM-100M+ and FSM-100P+, verify whether the application requires standard ELCT3-25 or large-diameter fiber ELCT3-25-LDF electrodes.

For legacy or unlisted Fujikura fusion splicers, provide the complete model number and current electrode marking because another electrode model may be required.
