This Visual Fault Locator (VFL) emits a 650 nm red laser beam with an output power of 100 mW, allowing the injection of a visible signal over a distance of 100 to 120 km into a single-mode or multi-mode fiber. The device offers two transmission modes: CW (Continuous Wave): continuous transmission for precise location, 2 Hz modulation: pulsed signal for rapid identification of loss or break points. It is equipped with a universal 2.5mm optical interface compatible with SC/ST/FC, and comes with an FC–LC adapter to also test 1.25mm connectors. Powered by 2 1.5 V batteries (included), the VFL guarantees an operational autonomy of more than 9 hours in standard use. The metal alloy housing incorporates a connector protection cap and ensures good heat dissipation as well as increased shock resist.
