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.
Page 10
1.2 Optical Pulse Measurement 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.
Waveform Display You can display the measured result as a waveform on the screen. You can zoom the displayed waveform and move the position that is displayed. How to View Optical Pulse Waveforms The optical pulse applied to the optical fiber is reflected at different points of the optical fiber such as its connections, bent sections, and the open end of the fiber.
Page 12
1.3 Waveform Display Splice Loss Because spliced sections of optical fibers have a great number of changes in the material’s density and inconsistencies in the fiber’s composition, loss due to Rayleigh scattering becomes large, and splice loss occurs in these sections. Reflection at the Connection Point of Connectors Using a connector to connect two optical fibers is different from splicing them together in that a small gap remains between the two fibers.
Page 13
Waveform and Event Analysis Waveform Analysis You can use the cursor and markers to measure values such as the distance, splice loss, return loss, or reflection level between two points. Measuring Distance The AQ1200x/AQ1205x measures the time that it takes for an incident optical pulse to be reflected and return to the device.
Page 14
1.4 Waveform and Event Analysis Dead Zone An area where the influence of a large event such as a connector’s connection point makes it impossible to recognize other events that exist in that area is a dead zone. There are the following two types of dead zones.
Page 15
1.4 Waveform and Event Analysis 4 Point Markers The AQ1200x/AQ1205x uses the following four points to perform the measurement: the measurement start point , the splice loss start point , the splice loss end point Y2, and the measurement end point .
Page 16
1.4 Waveform and Event Analysis Multi Trace Analysis You can load up to four traces that have been measured on the AQ1200x/AQ1205x and display them simultaneously for comparison. You can adjust the vertical display position of each loaded trace. 2 Way Trace Analysis Trace events that have been measured from optical fiber cable end A to end B and those measured from end B to end A can be combined.
Page 17
1.4 Waveform and Event Analysis Event Analysis You can search for events in the optical pulse measurement waveform and measure the splice loss and the return loss. Event Editing You can insert and delete events on the event screen. When you edit an event marker, the splice loss and the return loss can be recalculated.

Multi-Core Loss Test (Option) You can efficiently measure multi-core optical fiber and optical line degradation. This feature is available on models with the /SLT or /HLT option. Master and Slave Connect two AQ1200x/AQ1205xs and specify the optical power meter as the master and the light source as the slave.
Fault Locator This feature enables you to search for breaks (faults) in an optical fiber or line. If there are no faults in the middle of a fiber, the fiber end face is detected as a fault. You can specify the wavelength and the loss level that is used to determine if a fault is a fiber end face or not when the AQ1200x/AQ1205x searches for faults.
Checking Fiber End Faces You can use a fiber inspection probe to take a photograph that shows the state of a fiber end face. You can display this photograph on the AQ1200x/AQ1205x screen and save it. * For information about compatible fiber inspection probes, contact your nearest d dealer. Index 1-17 IM AQ1200-01EN...
