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.
