7. Operating Instructions

7.1 OTDR Testing

The OTDR function is used to characterize optical fibers. Ensure the fiber under test is clean and properly connected.

1. From the main menu, tap on the OTDR icon.
2. Connect the fiber to the OTDR port. Ensure the connector type matches (UPC/APC). Use appropriate adapters if necessary.
3. Tap Setup to configure test parameters.
4. Select the desired Wavelength (1310nm or 1550nm).
5. Choose the Mode (Auto-Test for automatic parameter selection or Manual for custom settings).
6. Adjust Avg. Time (averaging time), Range, and Pulse Width if in Manual mode.
7. Tap Test or Average to start the measurement.
8. The OTDR trace will be displayed on the screen, showing events like splices, connectors, and fiber ends.
