Visual Fault Locators

Professional Visual Fault Locators

Visual Fault Locators (VFLs) provide a fast and effective way to identify fibre breaks, bends, damaged connectors and continuity issues during fibre optic installation and maintenance. By projecting a visible red laser through the fibre, VFLs enable engineers to quickly pinpoint faults, verify routing and confirm fibre continuity.
