Overview
The Fluke Networks VisiFault is a robust, handheld visual fault locator (VFL) engineered to rapidly diagnose fiber optic connectivity issues. By emitting a bright red laser, it allows technicians to visually identify fiber breaks, damaged connectors on patch cords, defective splices within trays, and tight fiber bends in equipment racks.
Designed for field environments, the VisiFault features an impact-resistant, energy-absorbing holster and provides approximately 80 hours of battery life. It supports both continuous wave output for steady illumination and a flashing mode for enhanced fault visibility, ensuring efficient troubleshooting in diverse network infrastructure.
