No Fiber
No fiber is connected to
the OTDR port, or the
fiber is too short.
Connect a fiber to the port or to the launch cord.
If a fiber is connected:
 Make sure the connection is tight and there
are no breaks or cracks in the fiber near the
port.
 Clean and inspect the port connector.
 Do a Manual OTDR test with a narrow pulse
width.
Out of Range
The tester did not find
an end event.
This can occur for Manual OTDR tests when the
range you selected is too short. Select a higher
range on the TEST SETUP screen.
For Auto OTDR tests, Out of Range can occur
when the cabling is much longer than the range
of the module. Rarely, very bad connections
along the cabling can cause the OTDR to select a
range that is too short.
Compare the expected cabling length to the
maximum range of the module. If the length is
within range, try the Manual OTDR test with the
maximum range setting.
For DataCenter OTDR tests, Out of Range can
occur if the link is longer than the range of the
test.
Weak Signal
The signal is attenuated
below the background
noise level before the
tester found the end of
the fiber.
No fiber is connected to the OTDR port, the fiber
is too short, there is a bad connector in the link,
the fiber is broken or bent, or the fiber is very
long. Weak Signal can also occur if the fiber has
very high loss or you did a Manual OTDR and the
pulse width was too narrow.
No Signal
The tester did not
receive any reflected
light from the fiber or
from the OTDR port
connector.
There is a problem with the module. If this event
continues to occur, contact Fluke Networks for
assistance.
