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 — keeping your Fujikura splicer performing at factory specification between maintenance intervals.
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 — factors that third-party electrodes frequently cannot match.

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 — ensuring the splicer’s arc calibration produces consistent, low-loss splices throughout the electrode’s 5,000-splice service life.
- 5,000-Splice Service Life: Long electrode life reduces replacement frequency and maintenance cost — at one electrode change per 5,000 splices, the per-splice cost of genuine electrodes is minimal compared to the cost of re-splicing due to electrode-related failures.
- Tool-Free Field Replacement: The ELCT2-16B is 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 or unstable arc discharge, causing higher average splice loss and increased splice failure rates. 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: The ELCT2-16B is used in both single-fiber splicers (FSM-90S+, 88S, 31S, 41S) and ribbon splicers (88R, 90R) — 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 arc 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 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 Fusion Splicer
- Power off the splicer and allow it to cool if recently used
- Open the wind protector and locate the electrode holders on both sides of the V-groove
- Remove the old ELCT2-16B electrodes — tool-free, simply pull them out of the electrode holders
- Insert the new ELCT2-16B electrodes, ensuring correct seating and protrusion length in the electrode holders
- Close the wind protector and power on the splicer
- Run the arc calibration (arc check) from the splicer’s maintenance menu to calibrate the new electrodes
- 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.

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.

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. 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 ELCT2-16B electrodes?
A: No. The ELCT2-16B 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 ELCT2-16B 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.
Q: Are these genuine Fujikura electrodes?
A: Yes. These are genuine Fujikura ELCT2-16B electrodes with AFL part number S017103, ensuring full compatibility and original arc performance for your Fujikura splicer.
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, as well as all single-fiber models listed above.
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 (FSM-18S, FSM-60S, FSM-70S, FSM-80S, FSM-70R, FSM-19S, FSM-19R) with a ~4,000-splice life. Always verify your splicer model before ordering.
