Visual Fault Locator – VFL for Field Tester

Fault Locators are a special class of light sources that emit a high intensity visible Red Laser into a patch cable or cable. This light can be used to both check the continuity of a fiber and identify the fiber’s far end, or it can be used to visually identify the location of a fiber break.
Most Fault Locators come optimized for singlemode fiber use; however they work equally as well with multimode fiber.
