Specialty Fusion Splicers

Fusion splicing is the preferred joining method in advanced fiber work because it delivers low insertion loss, high mechanical strength, and long term stability. On specialty fiber, the variable that determines whether those three hold up is the shape of the heat.

A two electrode splicer heats from two points, so the plasma crosses the fiber from one side. That asymmetry is built into the hardware and cannot be tuned away with recipe adjustments. The three electrode Ring of Fire^® architecture wraps the fiber instead, applying uniform thermal energy around the full circumference. On hollow core, multi-core, and large diameter fiber, that difference is decisive.

The systems below cover cladding diameters from 80 µm to 2.5 mm, polarization maintaining, multi-core, hollow core, photonic crystal, and shaped cladding geometries. Selection depends on fiber type, alignment tolerance, optical performance target, and production volume. We are glad to work through the tradeoffs against your specific application.
