Fujikura ELCT2-16B Replacement Electrodes (AFL S017103) – FSM-90S+ 88S 88R 90R 31S 41S, 5,000 Splices

Fujikura ELCT2-16B Replacement Electrodes (AFL S017103) – Genuine Electrodes for Fujikura FSM-90S+, 88S, 88R, 90R, 31S & 41S Fusion Splicers

The Fujikura ELCT2-16B (AFL part number S017103) is the genuine OEM replacement electrode set for a wide range of Fujikura fusion splicers, including the high-performance FSM-90S+, FSM-90S, 88S+, 88S, 88R, 90R, 31S, and 41S. Rated for 5,000 arc discharges and designed for tool-free field replacement, the ELCT2-16B delivers consistent arc stability and low splice loss throughout its full service life.

Electrodes are the most critical consumable in arc fusion splicing. Using worn or degraded electrodes is the leading cause of increased splice loss, arc instability, and splice failures. Replacing with genuine Fujikura ELCT2-16B electrodes ensures correct electrode geometry, arc gap, and tungsten composition.

Key Specifications

Why Genuine Fujikura ELCT2-16B Electrodes Matter

• Guaranteed Compatibility & Arc Performance: Genuine OEM electrodes are manufactured to Fujikura’s exact specifications for electrode geometry, tungsten composition, and arc gap.
• 5,000-Splice Service Life: Long electrode life reduces replacement frequency and maintenance cost.
• Tool-Free Field Replacement: Remove the old electrodes, insert the new pair, run arc calibration, and resume splicing in minutes.
• Consistent Arc Stability: Genuine ELCT2-16B electrodes maintain stable, symmetric arc discharge from the first splice to the 5,000th.
• Compatible with Both Single-Fiber and Ribbon Splicers: One electrode part number covers your full Fujikura fleet.

Signs Your Fujikura Fusion Splicer Needs New Electrodes

• The splicer displays an electrode replacement warning or the electrode count approaches 5,000
• Splice loss is increasing on fiber types that previously spliced consistently within specification
• Arc discharge is visibly asymmetric or unstable during the fusion cycle
• 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

How to Replace Electrodes on a Fujikura Fusion 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 ELCT2-16B electrodes — tool-free, simply pull them out of the electrode holders
4. Insert the new ELCT2-16B electrodes, ensuring correct seating and protrusion length
5. Close the wind protector and power on the splicer
6. Run the arc calibration (arc check) from the splicer’s maintenance menu
7. Perform a test splice to verify splice loss is within specification before resuming production splicing

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

Frequently Asked Questions

Q: What is the Fujikura ELCT2-16B?
A: The Fujikura ELCT2-16B (AFL part number S017103) is the genuine OEM replacement electrode set for Fujikura FSM-90S+, FSM-90S, 88S+, 88S, 88R, 90R, 31S, and 41S fusion splicers. Each package contains one pair (2 electrodes) rated for approximately 5,000 arc discharges.

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

Q: How long do the Fujikura ELCT2-16B electrodes last?
A: The ELCT2-16B electrodes are rated for approximately 5,000 arc discharges.

Q: Do I need tools to replace the ELCT2-16B electrodes?
A: No. The ELCT2-16B is designed for tool-free field replacement.

Q: Do I need to calibrate the splicer after replacing electrodes?
A: Yes. After installing new ELCT2-16B electrodes, always run the splicer’s arc calibration (arc check) procedure before resuming splicing.

Q: Are these genuine Fujikura electrodes?
A: Yes. These are genuine Fujikura ELCT2-16B electrodes with AFL part number S017103.

Q: Are the ELCT2-16B electrodes compatible with the Fujikura 88R ribbon splicer?
A: Yes. The ELCT2-16B electrodes are fully compatible with the Fujikura 88R and 90R ribbon fusion splicers.

Q: What is the difference between ELCT2-16B and ELCT2-20A?
A: The ELCT2-16B is for newer Fujikura splicer models (FSM-90S+, 88S, 88R, 90R, 31S, 41S) with a 5,000-splice life. The ELCT2-20A is for older models with a ~4,000-splice life.
