Rexford Tools VFL-X20-LC Visual Fault Locator delivers a high output 20mW laser for detecting faults across fiber runs up to 20km.
The compact aluminum alloy fountain pen-style body is built for field work — lightweight at just 90g, with a built-in metal pen clip and a chain-tethered dust cap that keeps the connector head protected between uses.

This Visual Fault Locator offers 2 laser output modes: Constant On and Flashing.
A dedicated mode switch button cycles between them, and a hard power switch on the tail cap prevents accidental activation when the tool is in your pouch or bag.

If your job requires you to install or service fiber optic networks, a Visual Fault Locator is a must have for your tool pouch.
The VFL-X20-LC allows for finding bends and breaks, localizing damages, and doing end-to-end continuity checks on Single Mode Fiber Optic Cables — with nearly double the output power of a standard 10mW unit, making it the right choice for longer runs and higher-loss installations.
