The VLS-5 is compact but powerful visible fault locator designed troubleshoot on fiber optic cables. Light generated by these units will escape from sharp bends and breaks in jacketed or bare fibers, as well as poorly mated connectors. Thus they can identify faults in fiber optic jumper cables, distribution frames, patch panels, and splice trays.
The VLS-5 locates faults visually by creating a bright red glow at the exact location of the fault on singlemode or multimode fibers. The VLS-5 is powered by three 1.5V AAA batteries.
