Visual fault locators (VFL), also known as visual fault identifiers (VFI), consist of a visible red laser that is designed to inject visible light energy into fiber. The red light allows technicians to visually spot defects due to the red light escaping through any sharp bends, breaks, faulty connectors, or any other faults.
Visual fault locators/visual fault identifiers are essential tools for locating a large number of defects that occur at connection points in and around fiber cabinets that are considered hidden to an OTDR.
Avalon Test Equipment carries a variety of VFLs/VFIs to meet your testing requirements.
