1.6 Loss Test (Option)
You can easily measure optical fiber and optical line degradation. This feature is available on models
with the /SLT or /HLT option.
Auto Loss Test (Using one AQ1200x/AQ1205x as the light source
and another as the optical power meter)
Using the AQ1200x/AQ1205x as a light source and optical power meter, you can easily measure
optical fiber and line degradation. You can also use the AQ1100 multi-field tester series instead of the
AQ1200x/AQ1205x as the light source or optical power meter.
Light Source
You can set up to two measurement light wavelengths and produce them in order. You can produce
a constant level of light if you use the optical power adjustment feature.
Optical Power Meter
The AQ1200x/AQ1205x automatically identifies the measurement light from the AQ1200x/AQ1205x
that it is connected to and measures the optical power.
• The following items can be specified or executed. For details about these items, see section 1.5.
The unit, reference, offset, and threshold values can be specified.
The zero set and measured value display hold operations can be executed.
• You can attach
fiber information to the measured values and save them.
*
* Because the AQ1200x/AQ1205x is capable of identifying optical fiber and line cores, it is possible to
number cores and tapes.

Loop-Back Loss Test (Using one AQ1200x/AQ1205x)
You can use the light source and optical power meter features on a single AQ1200x/AQ1205x to
perform a loop-back loss test on an optical fiber or line. To perform loss testing, connect one end of the
fiber that you want to perform loss testing on to the AQ1200x/AQ1205x light source port, and connect
the other end to the optical power measurement port of the same AQ1200x/AQ1205x.
