Visual Fault Locator
The Visual Fault Locator (VFL) is a compact and powerful fiber optic testing tool used to detect fiber breaks, bends, faulty connectors, and splices in optical fiber networks.It emits a bright red laser light (650 nm) that travels along the fiber, making faults visibly glow in the damaged area.The device is an essential part of any fiber optic maintenance or installation toolkit, suitable for SM (Single Mode) and MM (Multi Mode) fibers.
