Fujikura ELCT2-16B Replacement Electrodes for FSM-88S/90S | Original, 5,000-Cycle Life, 1/5/10 Pair

Fujikura ELCT2-16B Replacement Electrodes for FSM-88S / FSM-90S –  Original, 5,000-Cycle Life

The Fujikura ELCT2-16B is the genuine  replacement electrode for Fujikura FSM-88S and FSM-90S fusion splicers — and the most popular electrode replacement part for the FSM-series platform. Made from high-purity tungsten alloy to Fujikura’s exact specifications, each pair delivers up to 5,000 arc cycles of stable, symmetric arc discharge for consistent low-loss splices.

Available in 1 pair, 5 pair, and 10 pair options — ideal for individual technicians, field crews, and service centers who want to stock up and minimize downtime. Worn electrodes are the #1 cause of high splice loss and arc calibration failures on FSM-88S and FSM-90S splicers. Replacing with genuine ELCT2-16B electrodes is the fastest, most cost-effective way to restore factory-spec performance.

Technical Specifications

When to Replace Your FSM-88S / FSM-90S Electrodes

Replace your ELCT2-16B electrodes every 3,000–5,000 arc discharges, or immediately if you observe any of the following on your FSM-88S or FSM-90S:

• Increasing average splice loss despite correct fiber preparation and cleave quality
• Frequent arc calibration failures or arc check errors
• Visible electrode tip erosion, pitting, or asymmetric wear
• Splicer error messages related to arc power or electrode condition
• Inconsistent splice results on previously reliable fiber types

Package Contents

• Fujikura ELCT2-16B Electrodes × 1 pair (or 5 / 10 pairs depending on selected option)

Frequently Asked Questions

Q: Are these genuine Fujikura OEM electrodes or aftermarket?
A: These are 100% genuine OEM Fujikura ELCT2-16B electrodes — not aftermarket or compatible replacements. They are manufactured by Fujikura to the same specifications as the electrodes shipped with new FSM-88S and FSM-90S splicers.

Q: What is the difference between buying 1 pair vs. 5 or 10 pairs?
A: All options contain the same genuine ELCT2-16B electrodes. The 5-pair and 10-pair options offer better per-pair value and are ideal for field crews, service centers, or technicians who want to maintain a stock of replacement electrodes to minimize splicer downtime.

Q: How do I replace the electrodes on my Fujikura FSM-88S or FSM-90S?
A: Open the wind protector and V-groove cover, remove the worn electrodes using the electrode removal tool, insert the new ELCT2-16B electrodes ensuring they are fully seated, then run the splicer’s arc calibration (arc check) routine before resuming splicing. Always handle electrodes by the body — never touch the tungsten tips with bare hands.

Q: Do I need to run arc calibration after installing new electrodes?
A: Yes. Always run the arc calibration routine after installing new ELCT2-16B electrodes. This allows the FSM-88S or FSM-90S to characterize the new electrodes and optimize arc power for your current altitude and environmental conditions.

Q: What warranty do these electrodes come with?
A: Fusion splicer electrodes are consumable items and are not covered by a product warranty — this is the industry standard across all brands including Fujikura, Sumitomo, INNO, and AFL. For bulk pricing or technical questions, contact us at info@splicermarket.com.
