1.2 Optical Pulse Measurement
The AQ1200x/AQ1205x applies an incident optical pulse to the connected optical fiber and measures
the power level of the reflected light from the different sections of the optical fiber such as its splices,
bent sections, and the open end of the fiber. The AQ1200x/AQ1205x uses the measured power level
to determine the distance to the different points (splices, breaks, etc.) of the optical fiber and the loss
and other phenomena that occur at those points.

Measurement Mode
The following three measurement modes are available depending on the items that you specify for
measurement conditions.
Simple
In this mode, you can set the optical wavelength and turn the automatic saving of measured data on
and off. All other measurement conditions are automatically configured or are fixed.
Detail
In this mode, you can set all measurement conditions.
Multi WL
In this mode, in addition to the settings that you can specify in Detail mode, you can select up
to two optical wavelengths. The optical pulse whose wavelength you specified first is generated
and measured. Next, the optical pulse whose wavelength you specified second is generated and
measured. This operation is then repeated.
Analysis Mode
The following three analysis modes are available depending on the items that you specify for analysis
conditions.
Simple
In this mode, you can set the approximation method. All other analysis conditions are automatically
configured or are fixed.
Detail
In this mode, you can specify all analysis conditions.
Multi WL
In addition to the conditions in Detail mode, you can specify the index of refraction and the
backscattering light level for each of the two wavelengths that you specified in the measurement
Multi WL mode. You can also turn the macro bending (bending loss) display on and off.
