Optical Time Domain Reflectometers (OTDR) provides 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 to and skill to operate.

Fiber QuickMap fills the gap between a VFL and an OTDR. These models have the simplicity of a VFL, and provide distance and power information on high losses, breaks, and the end of the fiber. They also identify live fiber.

FQM-100-M-VFL Includes multimode fiber fault locator unit, screw on interchangeable SC adapter, UPC-UPC 2-meter patch cord, carrying case, 4-language Quick Reference Guide (manuals in 9 languages available on-line), safety instruction manual, and batteries. VisiFault Visual Fault Locator with 2.5 mm universal adapter is also included.
