SPLICING MACHINE ELECTRODES - PER PAIR

Electrodes

Replacement arc discharge electrodes for fusion splicing machines. These precision tungsten (or tungsten alloy) tips generate the electric arc that melts and fuses fiber ends. Over time, electrodes erode due to high-temperature arcing, leading to inconsistent splices, increased splice loss, and arc stability warnings from the splicer. The typical lifespan is 3,000–5,000 splices, after which replacement is recommended. Electrodes are sold as matched pairs and must be installed with precise tip alignment (gap and protrusion) per the splicer manufacturer's specifications. Different models are designed for specific fusion splicer brands (Fujikura, Sumitomo, Inno, Furukawa, Corning, etc.) and fiber types (standard SM, MM, or large-diameter fibers). After installation, the splicer's arc calibration routine must be performed to optimize discharge parameters for the new electrodes. Genuine electrodes or high-quality third-party equivalents ensure splice quality and equipment warranty compliance.

• Material: Tungsten (99.95% pure) or tungsten alloy (with rhenium or lanthanum for extended life)
• Tip Design: Pointed (standard SM/MM) or flat (for large-diameter fibers, LDF)
• Lifespan: 3,000–5,000 splices (depends on arc intensity, fiber type, cleaning routine)
• Compatibility: Fujikura (various series), Sumitomo (Type 25/35/45/71/81), Inno (View series), Furukawa (S series), Corning, others
• Pair: Sold as a matched set (two electrodes, serialized for consistency)
• Installation: Requires hex driver or screwdriver (included with most splicers), alignment gauge recommended
• Signs of Wear: Arc point wandering, increased splice loss, "clean electrodes" warning messages
• Storage: Keep in protective case to prevent tip damage; do not touch tips with bare hands
