Analyzing Traces and Events

OTDR 141

Enabling or Disabling the Detection of Reflective Ends of Fiber

To enable or disable the detection of reflective ends of fiber:

1. From the Main Menu, tap Test Configuration.

2. From the Apply to list, select Current acquisition.

3. From the Test Configuration dialog box, go to the Link Definition tab.

4. If you want to enable the option, under End-of-Fiber, select the

Reflective end-of-fiber detection box.

If you prefer to disable the option, clear the box.

5. Tap OK to return to the main window.

IMPORTANT

The analysis will stop as soon as the loss of an event crosses the

end-of-fiber (EoF) threshold. The application will mark the event as

an end-of-fiber event.

In this case, even if you selected the option, the application will not

search the “noisy” portion of the trace for reflective ends of fiber.

If you want to do so, you will have to increase the EoF threshold

(see Setting the Analysis Detection Thresholds on page 30).
