Real-time Measurement
In real-time measurement, you can change measurement conditions such as the wavelength, distance
range, and pulse width while waveform changes are being measured in real time.
*
* The measurement conditions that you can change vary depending on the measurement mode. For details
about the measurement conditions, see the explanation of the measurement modes in chapter 3.
Averaged Measurement
When you want to detect reflections, splice loss, and other faint events that are generated from
connections or splice points but are buried in noise, use averaged measurement. The AQ1200x/
AQ1205x derives the measured data by averaging the specified number of optical pulse
measurements or by averaging optical pulse measurements over the specified duration. During
averaged measurement, you cannot change the measurement conditions. You can stop the averaged
measurement before it completes.
Multi-Core Fiber Measurement
Using screens and setup menus specific to multi-core fiber measurement, you can efficiently and
completely measure multi-core fibers.
Fiber-in-Use
Some models in the AQ1200x/AQ1205x use the same wavelength that is used in real communication
to make measurements.
If communication light is present in the optical fiber that you want to measure (the fiber is in use), the
communication will be affected. In this situation, the AQ1200x/AQ1205x will not be able to perform
measurements correctly either. Take appropriate precautions to avoid communication interference.
Check that there is no communication light present in the optical fiber before you use the AQ1200x/
AQ1205x. The AQ1200x/AQ1205x has a feature for checking whether there is communication light
(fiber-in-use alarm; see section 3.5).
