To use the visual fault locator
You can connect the visual fault locator to
connectors that have 2.5 mm ferrules (SC, ST, or
FC). To connect to other ferrule sizes, use a test
reference cord with the correct connector at one
end and a SC, ST, or FC connector at the tester
end.
1 Clean and inspect the connectors on the patch cord, if used,
and the fiber to be tested.
2 Connect the fiber directly to the VFL port or use the patch
cord to connect to the port.
3 Use the VFL button to turn on the visual fault locator (refer to
Figure 29).
Or, on the home screen tap TOOLS, then tap Visual Fault
Locator (VFL). You can tap the PULSE/OFF/CW (continuous
wave) button on the screen to change the modes of the VFL, or
use the button as shown in Figure 29.
4 Look for the red light as shown in Figure 29.
5 To see the light that comes out of a connector, hold a white
paper in front of the fiber connector.
The fiber connector at the VFL and the fiber near
the connector can emit red light when there are
no faults there because the light is strong at the
VFL output.
The light from the VFL is possibly not visible
through dark-colored fiber jackets.
