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 resistance.

The set is supplied with a carrying case.
Dimensions: 175 × 26 × 26 mm
