Fluke Networks Fiber OneShot PRO [FOS-100-S-VFL] Single Mode Fiber Fault Locator with VisiFault

The Fluke Networks FOS-100-S-VFL Fiber OneShot PRO Single Mode Fiber Distance and Fault Locator measures length and identifies high loss events on single mode fiber optic cable. Like an OTDR, a laser sends light pulses through the fiber and measures the power and timing of light reflected from high loss connections and splices, and the end of the fiber.

VFLs work well for exposed lengths of fiber near a patch panel by illuminating bad connections and breaks. They are not very helpful for cable runs more than a few meters, or when the cable is not visible or accessible, or when the laser light can’t penetrate the jacket. Optical Time Domain Reflectometers (OTDR) provide graphical data and analysis along the entire length of a cable, way beyond the reach of a VFL, but they can be expensive and require more time and skill to operate. The FOS-100-S-VFL Fiber OneShot PRO fills the gap between a VFL and an OTDR. The FOS-100-S-VFL has the simplicity of a VFL, and provides distance and power information on high losses, breaks, and the end of the fiber. The Fiber OneShot PRO also identifies live fiber.

The FOS-100-S-VFL includes the VisiFault Visual Fault Locator with 2.5 mm universal adapter. Fluke Networks VisiFaultTM Visual Fault Locator (VFL) allows you to diagnose and repair simple fiber link problems. The laser-powered VisiFault Visual Fault Locator is 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. Compatible with 2.5mm and 1.25mm connectors for easy connection. Ruggedly constructed for demanding field-testing. This visual fault locator has a long battery life for hours of use.
