Identifying Fiber Faults Visually with the VFL
Identifying Fiber Faults Visually with the VFL
Your unit can be equipped with an optional visual fault locator (VFL) to
help you identify bends, faulty connectors, splices and other causes of
signal loss. It can also help the person at the other end of the link to identify
the fiber under test, which could be particularly useful when working with
cables containing many fibers.
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 (CW) or
blinking (1 Hz).
The VFL is available either in Live mode or Capture mode. It can be
switched from one state to another (on, off or blink).
W
ARNING
When the VFL is active, the VFL port emits visible laser radiation.
Avoid exposure and do not stare directly into the beam. Protect any
unused port with a cap.
