During the installation of new glass fiber connections or in the diagnosis of an existing network, the following applies: the faster a problem is found, the faster it is released. But this is easier said than done when it comes to a complex network with glass fibers, connection components and patch cables. Basic problems in fiber-optic connections can be made with the VisiFaultTM Visual Fault Locator (VFL) from Fluke Networks diagnose and repair. The with laser light working Visual Fault Locator (VFL) of VISI fault checks glass fibers, Continuity and polarity. This cable continuity tester helps breaks in cables, connections and splicing. For easier identification, it can be operated with continuous light or gepulstem light. It is with 2.5-mm and 1.25-mm connectors compatible. So robust that it even the toughest of conditions in the field. This visual fault locator has a long battery life for hours of use.
