13.1 Locating Breaks (Faults) in Optical Fibers
Explanation
Fault Location Display
The fault locator uses averaged measurements to detect faults. The cursor position is automatically
set to a fault location on the waveform, and the distance from the measurement reference point to the
fault is displayed.
Faults are not detected during real-time measurement. In the fault locator’s real-time measurement,
you can perform cursor operations or select the wavelength during measurements. If you cancel
measurements prematurely, faults will not be detected.
Distance Unit
You can select the distance unit that is displayed on the screen from the units shown below.
km, mile, kfeet
If you set the AQ1200 language to JAPANESE, the distance unit is fixed to km. For the setup
procedure, see section 5.5.
