Description

The KARVINGER KEFOK6 Fusion Splicer is a professional-grade 6-motor core alignment system engineered for high-stakes fiber deployments.

Utilizing advanced image processing and six-motor autofocus technology, it provides precise, low-loss splicing for SMF, MMF, DSF, and NZDSF fibers.

The all-in-one design integrates a high-performance Visual Fault Locator (VFL) and Optical Power Meter (OPM) directly into the chassis, streamlining field workflows and reducing the need for external diagnostic tools.
