Visual Fault locators VFL

Visual Fault locator patch cord and pigtail manufacture line

A visual fault identifier or visual fault locator (VFI / VFL) is a visible red laser designed to inject visible light energy into a fiber. Sharp bends, breaks, faulty connectors and other faults will “leak” red light allowing technicians to visually spot the defects.

The VFI is an ideal tool for locating a large number of defects that occur at connection points in and around fiber cabinets which are hidden in an OTDRs “blind-spot” or dead-zone.

The laser-powered VFLis a cable continuity tester that locates fibers, verifies cable continuity and polarity. This cable continuity tester helps find breaks in cables, connectors, and splices. Continuous and flashing modes make for easier identification.

Applications

Locate sharp bends, breaks, and damages in fiber
Conduct end-to-end continuity tests
Perform fiber tracing and identification
