Visual Fault Locators
Every tool calibrated before dispatch, stocked in the US and covered by a 24-month warranty.
A visual fault locator (VFL) sends a bright red 650 nm laser down an optical fiber so that breaks, sharp bends, and faulty connectors light up and become visible to the naked eye. It's the fastest, simplest way to confirm continuity and physically locate a fault along a fiber run.
Karvinger VFLs are built for working technicians: a high-power 50 mW output for reach on long spans, continuous and flashing modes, a rugged rechargeable body, and SC/FC/ST compatibility with an LC adapter included.
