Which tool is used to locate breaks in fiber by emitting visible light?

Explanation:
Locating fiber breaks by emitting visible light is what a visual fault locator (VFL) does. It injects a visible-light source into the fiber, and when there’s a break or fault, the light leaks out and you can see the glow at the location. This makes it easy to pinpoint the break quickly. It isn’t used to measure attenuation (that needs a calibrated light source and power meter), splice fiber (needs a splicer), or terminate connectors (needs termination tools).
