How to Do Tests Through Attenuators
The troubleshooter gives accurate results through attenuators
that have 1 dB to 2 dB of attenuation.
Attenuators with more than 2 dB can possibly cause the
troubleshooter to miss events. To do tests on fibers that have
attenuators with more than 2 dB, connect directly to the fiber
after the attenuator. In general, you should not do tests through
attenuators.
Measurement Results
The troubleshooter measures the loss and reflectance of
incidents on the fiber and the distance to the incidents. Typically,
an incident is the end of the fiber, a connection, or a fault such
as a break or a bad splice. See Figures 8 and 9.
If there is a break or an open connection on the fiber, the
troubleshooter does not show incidents after the break.
To see the results for other incidents, press

troubleshooter shows up to 9 incidents.
