Visual Fault Locator Applications
The visual fault locator (VFL) is available with OFTM-573x
modules. The VFL 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.
Using the Visual Fault Locator
•
•
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.)
