Event Possible Causes and Solutions
WEAK SIGNAL
The signal is attenuated below
the background noise level
before the end event is reached.
No fiber is attached to the OTDR port, the fiber is too short, or there is a bad connector
or broken fiber somewhere near the tester. May also occur if the fiber has very high
loss, or if the tester is in Manual OTDR mode and the
PULSE WIDTH is too narrow.
If the OTDR trace and event table show that the fiber is very short, check for bad
connections and broken fibers within a few meters of the tester.
NO FIBER
No fiber is attached or the fiber is
too short to measure.
No fiber is attached to the OTDR port, the fiber is too short, or there is a bad connector
or broken fiber somewhere near the tester.
Check for bad connections and broken fibers within a few meters of the tester.
NO SIGNAL
There is a problem with the
module.
