Fujikura ELCT2-20A Replacement Electrodes – AFL Spare Electrodes for FSM-18S FSM-60S FSM-70S FSM-80S FSM-70R FSM-19S FSM-19R

Fujikura ELCT2-20A Replacement Electrodes – Genuine AFL Spare Electrodes for FSM-18S, FSM-60S, FSM-70S, FSM-80S, FSM-70R, FSM-19S & FSM-19R Fusion Splicers

The Fujikura ELCT2-20A is the genuine OEM replacement electrode set for a wide range of Fujikura FSM-series fusion splicers, including the widely deployed FSM-60S, FSM-70S, FSM-80S, FSM-70R, FSM-18S, FSM-19S, and FSM-19R. These are the correct AFL-specified spare electrodes for maintaining arc stability and splice quality in Fujikura’s mid-generation splicer platform — the workhorses of FTTH construction and telecom OSP splicing worldwide.

Electrodes are the most critical consumable in arc fusion splicing. As tungsten electrodes oxidize and erode over thousands of arc discharges, arc discharge becomes asymmetric and unstable — causing increased splice loss, splice failures, and failed arc calibrations. Replacing with genuine Fujikura ELCT2-20A electrodes restores arc stability and returns splice loss to factory specification.

Key Specifications

Why Genuine Fujikura ELCT2-20A Electrodes Matter

• Guaranteed OEM Compatibility: Genuine ELCT2-20A electrodes are manufactured to Fujikura’s exact specifications for electrode geometry, tungsten composition, and arc gap — ensuring the splicer’s arc calibration produces consistent, low-loss splices throughout the electrode’s service life. Third-party electrodes frequently deviate from OEM geometry, causing arc instability that the splicer’s calibration cannot fully compensate for.
• ~4,000-Splice Service Life: Rated for approximately 4,000 arc discharges — replace at the splicer’s electrode replacement warning or when splice quality degrades, whichever comes first.
• Tool-Free Field Replacement: Designed for tool-free replacement directly in the field — no screwdrivers, no service centre visit. Remove the old electrodes, insert the new pair, run arc calibration, and resume splicing in minutes.
• Consistent Arc Stability: Worn electrodes produce asymmetric arc discharge, causing higher average splice loss and increased splice failure rates. Genuine ELCT2-20A electrodes maintain stable, symmetric arc discharge from the first splice to the last.
• Compatible with Both Single-Fiber and Ribbon Splicers: The ELCT2-20A covers both single-fiber splicers (FSM-60S, FSM-70S, FSM-80S, FSM-18S, FSM-19S) and ribbon splicers (FSM-70R, FSM-19R) — one electrode part number for your full FSM-series fleet.

Signs Your Fujikura FSM Splicer Needs New Electrodes

• The splicer displays an electrode replacement warning or the electrode arc count approaches 4,000
• Splice loss is increasing on fiber types that previously spliced consistently within specification
• Arc discharge is visibly asymmetric or unstable during the fusion cycle when viewed through the splicer’s camera
• Splice failures, bubble defects, or fat splices are occurring more frequently
• The splicer’s arc calibration (arc check) is failing or requiring repeated re-calibration
• Visible white tungsten oxide deposits on the electrode tips when inspected through the splicer’s camera

How to Replace Electrodes on a Fujikura FSM Splicer

1. Power off the splicer and allow it to cool if recently used
2. Open the wind protector and locate the electrode holders on both sides of the V-groove
3. Remove the old ELCT2-20A electrodes — tool-free, simply pull them out of the electrode holders
4. Insert the new ELCT2-20A electrodes, ensuring correct seating and protrusion length in the electrode holders
5. Close the wind protector and power on the splicer
6. Run the arc calibration (arc check) from the splicer’s maintenance menu to calibrate the new electrodes
7. Perform a test splice to verify splice loss is within specification before resuming production splicing

Always follow the electrode replacement procedure in your Fujikura splicer’s user manual for your specific model.

ELCT2-20A vs. ELCT2-16B: Which Fujikura Electrode Do You Need?

If you are unsure which electrode your Fujikura splicer uses, check the splicer’s maintenance menu or user manual under the electrode replacement section, or contact us with your splicer model number and we will confirm the correct part.

Ideal Applications

• FTTH / FTTx network construction — maintaining consistent low-loss splices during high-volume fiber deployment with Fujikura FSM-60S, FSM-70S, or FSM-80S splicers
• Ribbon fiber splicing — electrode maintenance for Fujikura FSM-70R and FSM-19R ribbon splicers used in high-density fiber cable splicing
• Telecom OSP fiber splicing — aerial, underground, and in-building fiber splicing maintenance for FSM-series splicers
• Data center fiber infrastructure — precision splicing for backbone and inter-rack fiber connections
• Preventive maintenance programs — scheduled electrode replacement to maintain consistent splice quality across field teams operating multiple Fujikura FSM-series splicers

Frequently Asked Questions

Q: What is the Fujikura ELCT2-20A?
A: The Fujikura ELCT2-20A is the genuine replacement electrode set for Fujikura FSM-18S, FSM-60S, FSM-70S, FSM-80S, FSM-70R, FSM-19S, and FSM-19R fusion splicers. Each package contains one pair (2 electrodes) rated for approximately 4,000 arc discharges.

Q: Which Fujikura splicer models use the ELCT2-20A electrodes?
A: The ELCT2-20A is compatible with the Fujikura FSM-18S, FSM-60S, FSM-70S, FSM-80S, FSM-70R, FSM-19S, and FSM-19R. For FSM-90S+, FSM-90S, 88S, 88R, 90R, 31S, and 41S models, the correct electrode is the ELCT2-16B.

Q: How long do the Fujikura ELCT2-20A electrodes last?
A: The ELCT2-20A electrodes are rated for approximately 4,000 arc discharges. Replace them when the splicer displays an electrode replacement warning, when splice loss increases unexpectedly, or when arc discharge becomes visibly unstable.

Q: Do I need tools to replace the ELCT2-20A electrodes?
A: No. The ELCT2-20A is designed for tool-free field replacement — simply remove the old electrodes and insert the new pair. No screwdrivers or service centre visit required.

Q: Do I need to calibrate the splicer after replacing electrodes?
A: Yes. After installing new ELCT2-20A electrodes, always run the splicer’s arc calibration (arc check) procedure before resuming splicing. This calibrates the arc power and timing for the new electrodes and ensures splice loss returns to specification. Skipping arc calibration after electrode replacement will result in poor splice quality.

Q: What is the difference between ELCT2-20A and ELCT2-16B?
A: The ELCT2-20A is for Fujikura’s mid-generation FSM-series splicers (FSM-60S, FSM-70S, FSM-80S, FSM-70R, etc.) with a ~4,000-splice life. The ELCT2-16B is for newer models (FSM-90S+, 88S, 88R, 90R, 31S, 41S) with a ~5,000-splice life. Always verify your splicer model before ordering.

Q: Are the ELCT2-20A electrodes compatible with the Fujikura FSM-70R ribbon splicer?
A: Yes. The ELCT2-20A electrodes are fully compatible with the Fujikura FSM-70R and FSM-19R ribbon fusion splicers, as well as all single-fiber FSM models listed above.

Q: Are these genuine Fujikura / AFL electrodes?
A: Yes. These are genuine Fujikura ELCT2-20A electrodes as specified by AFL, ensuring full OEM compatibility and original arc performance for your Fujikura FSM-series splicer.
