The TechLogix TL-VFL-1MW is a compact fiber optic visual fault locator (affectionately known as a "VFL") that's ideal for locating breaks and out-of-spec bends in a fiber optic cable. It's also a crucial tool for verifying mechanical fiber optic connectors are terminated properly and identifying strands during splicing and/or patching. The VFL-1MW features a 1mW output which drives a visible laser signal up to 5km. Plus, two modes of operation -- continuous wave output and flashing wave output -- help identify different strands and cable runs. The VFL-1MW features battery power and a 2.5mm universal connector, which is designed for use with SC, ST and FC style connectors (integration with LC style connectors requires a 2.5mm to 1.25mm adapter). Both single mode and multimode fiber are supported.
