    Red light leakage at the fiber optic cable splice

    A Visual Fault Locator is a simple yet powerful diagnostic tool that injects a bright visible red laser (typically 650–670 nm) into a fiber. When the light encounters a fault—such as a break, bad splice, or sharp bend—it leaks through the fiber cladding, making the issue visible to. Or it could be caused by the quality of the connector itself, such as poor end-face geometry that doesn't pass the parameters defined by IEC PAS 61755-3 standards, including angle of the polish, fiber height, radius of curvature or apex offset.
