10 Identifying Fiber Faults

Visually

Note: This feature is available only if your unit is equipped with a VFL port.

The visual fault locator (VFL) helps you identify bends, faulty connectors,

splices and other causes of signal loss.

From its dedicated port, the VFL emits a red signal which becomes visible

at the location of a fault on the fiber. This signal can be continuous (the

default) or blinking (1 Hz).

³ The VFL status is indicated with a LED in the

status bar and with the Active indicator

under the keypad.

Note: The Active indicator always shows the VFL or

OTDR status (even in idle mode).

WARNING

When the VFL is active, the VFL port emits visible laser radiation.

Avoid exposure and do not stare directly into the beam. Ensure that

any unused port is properly protected with a cap.
