OTDR Test mode: click the "measurement mode" box to pop up five modes of measurement tasks (automatic, manual, real-time, fault finder and task mode), which have different functions： ① Automatic mode: the wavelength type and duration can be customized in the automatic mode, and the test range and pulse are returned by the OTDR module. When you are not clear about the length and pulse size of the measured optical fiber, you can choose the automatic mode. Figure 4.
OTDR Figure 4.2-4 Manual mode ③ Real time mode: the real-time mode can customize the wavelength type, test range and pulse; However, the duration cannot be changed. It is fixed to test all the time, and the measurement needs to be stopped manually. Real time mode is a method we provide to observe the curve trend for a long time. Figure 4.
OTDR Figure 4.2-5 Fault Finder mode ⑤ Task mode: task mode is a mode provided by us to facilitate users to quickly use OTDR. When the measurement mode selects the default task, the "default task" column on the right is no longer grayed out and becomes operable. We can see some built-in tasks in the task list. Various parameters of these tasks have been set. Just select them and click the measurement button to start the test. Figure 4.
OTDR Figure 4.2-6 task list Default task: in the default task column, you can select some tasks brought by the system to help you quickly complete parameter settings. Click the default task column to see a list of some common tasks preset by us. The parameters are separated by underline. From left to right, they are wavelength, range, pulse and duration. Figure 4.
OTDR If these preset tasks cannot meet your needs, you can also add some custom tasks to facilitate your multiple measurement and use. Click "+" on the right, and the task name input box will pop up. After entering the user-defined task name, the task will be added to the default task list. Then you can select the custom task to measure. Wavelength: click the wavelength box to switch the wavelength. The system provides two types of wavelengths (1310nm and 1550nm) for measurement.
OTDR Figure 4.2-9 Test range selection Pulse: click the pulse box to switch the test range. The system provides 11 types of pulses (5ns, 10ns, 30ns, 50ns, 100ns, 275ns, 500ns, 1us, 2.5us, 10us and 20us). The selection of pulses needs to be changed according to the test range. Selecting appropriate pulses can improve the accuracy of the test. Figure 4.
OTDR Duration: click the duration box to switch the duration. The system provides nine test durations (5S, 10s, 15s, 30s, 45s, 60s, 90s, 120s and 180s). Theoretically, the length of time will affect the accuracy of the test. The longer the time, the higher the accuracy of the event point.

On the setting page, you can see the threshold parameter setting interface.
OTDR Figure 4.3-1 Threshold parameters page Wavelength: 1310nm and 1550nm wavelengths can be selected in the "wavelength" box in the threshold parameter. The two wavelengths can be switched with each other. After editing the relevant parameters of the corresponding wavelength separately, the parameters of other wavelengths will not change. When measuring, the threshold parameter of the corresponding wavelength will be read to judge whether the curve passes or not.
OTDR Figure 4.3-2 Parameter page of 1550nm For example, after the wavelength is 1310nm, adjust the welding loss to 0.06, and then switch the wavelength to 1550nm. It is found that the parameter in the column of welding loss is still 0.5 and has not changed. When the wavelength is switched to 1310nm again, the welding loss will be displayed as 0.06. Backscattering: the "backscattering" box in the threshold parameter can change the value of backscattering.
OTDR Figure 4.3-3 Event point interface Welding loss: the "welding loss" box in the threshold parameter can change the threshold of welding loss. When "welding loss" is checked, the test result will verify the welding loss. When the welding loss in the measurement result is greater than the set value, the curve judgment will not pass, and the threshold range of welding loss is 0.06 ~ 0.5dB. If event points 2 and 3 in figure (4.
OTDR Figure 4.3-4-3 Reflectivity: the "reflectivity" box in the threshold parameter can change the threshold of reflectivity. When "reflectivity" is checked, the test result will be verified for reflectivity. When the reflectivity in the measurement result is greater than the set value, the curve judgment will not pass, and the threshold range of reflectivity is - 80 ~ 0dB. For example, 1, 4 and 5 in figure (4.
OTDR When the diameter distance loss in the measurement result is greater than the set value, the curve judgment will not pass, and the threshold range of diameter distance loss is 0 ~ 45dB. As shown in the column of diameter distance loss in figure (4.3-6). (the principle is consistent with the determination of welding loss and reflectivity, but the judgment parameter position is transferred from the event point list to the detailed information interface.
OTDR connector loss is 0.06 ~ 5dB. For example, 1, 4 and 5 in figure (4.3-3) are reflection events (the meaning of the event type icon can be seen in the event type description in Appendix A). The values in the loss column of 1, 4 and 5 will participate in the determination of connector loss.
OTDR As shown in the column of radial distance ORL in figure (4.3-4). (the principle is consistent with the determination of welding loss and reflectivity, but the judgment parameter position is transferred from the event point list to the detailed information interface. When the value of diameter distance ORL is greater than the set threshold, the value of diameter distance ORL will also be marked in red) Figure 4.
OTDR Figure 4.4-1 Link parameter setting page Helix Factor：It is used to represent the actual length of the optical cable. The optical fiber revolves around the central axis in the optical cable tray. If it is necessary to test the length of the optical cable, the Helix Factor needs to be used. After setting the Helix Factor, the measured "position / length" follows the following formula: D (position, length) = (1 - reinforcement coefficient) * measured value.
OTDR radial distance becomes event 1 and its distance reference becomes 0. Events that are excluded from the fiber pitch are grayed out in the event table and no longer appear in the curve display. The cumulative loss is calculated only for the defined fiber diameter. 4.4 Set user information Click the setting button to open the setting page.
