TEST PROCEDURES
CONTINUITY
OPM MODE
To ensure fibers are installed into a patch panel in the correct order, or need to trace a particular fiber from one end to the other, connect a light source to one end of
the fiber link, then connect the Fiber OWL 7 into each fiber at a time until a proper reading appears on the display.
Connect the light source into the fiber port being verified, then connect the Fiber OWL 7 into the fiber ports
one at a time. Connecting into the wrong port will result in a very low power reading.

Once the meter is connected to the same fiber (continuity achieved), a reading that is close to the light
source’s calibration power level will appear.
