PM-501X-VFL Power Meter & Visual Fault Locator


The PM-501X-VFL from PRO combines an Optical Power Meter and Visual Fault Finder in one easy to use unit, reducing the need to carry two different testing tools and lowering costs.

The VFL has three different output power settings so it’s like having 3 VFL’s in one unit plus a power meter. The PM-501A-VFL power meter has a broad measuring of -50 dBm ~ +26 dBm, and PM-501B-VFL power meter function has a broad measuring range of -70 dBm ~ +6 dBm. It can measure the 6 most commonly used fiber optic wavelengths.
