Locating Fibers and Faults with the Visual Fault Locator
Visual Fault Locator Applications
The fiber test module includes a visual fault locator that
helps you do the following:
• Quickly check fiber continuity. Trace fibers to
determine the polarity of duplex connections and
identify connections between patch panels.
• Locate breaks and bad splices. These faults scatter
the locator’s light, causing a red glow in the affected
area.
• Reveal high-loss bends. If the locator’s light is visible
around a bend in a fiber, the bend is too sharp.
• Reveal problems in connectors. A damaged fiber
inside a connector causes a red glow in the
connector.
• Optimize mechanical splices and pre-polished
connectors: Before sealing the splice or connector,
adjust the fiber alignment for minimal glow where
the fibers meet. (Follow the manufacturer’s assembly
instructions for splices and connectors.)
