App
13.1 Locating Breaks (Faults) in Optical Fibers
The AQ1200 is equipped with a feature that you can use to locate and display faults in optical fibers.
This feature works by performing an OTDR averaged measurement and then automatically performing
an OTDR event analysis.
Use the OTDR feature to analyze waveforms.
Procedure
Fault Locator Screen
1.
Using the
rotary knob
and
ENTER
, select
Fault Locator
to display the following screen.
Set the wavelength .
The available options vary depending
on the model.
For details, see the explanation in
section 3.5.
Press to move the distance
reference (see section 6.3).
Press to access the OTDR feature
(see chapters 3 to 7).
If you press this soft key, the OTDR
screen will be displayed. After you
use the OTDR feature to perform
analysis, to return to the fault locator
feature, press
MENU
, and then
press the
Fault Locator
soft key.

Press
SETUP
to display the following screen.
Set the wavelength.
See “Explanation” in section 3.5.
Set the end of fiber (Fresnel reflection; 3dB to 65dB).

Measuring
3.
Press
AVG
to start the averaged measurement. When the averaged measurement completes,
the fault locations are automatically displayed.
Note
You can save measured data, but saved waveform data cannot be loaded on the AQ1200. For details on
