Analyzing Traces with the Bidirectional Analysis Application

OTDR 207

Viewing Results

³ When you select an element from the summary table (or if you switch

to another wavelength or direction), the graph, as well as the contents

of the Events and Trace Info. tabs are updated accordingly.

³ In the summary table, when you select an element having a “fail”

status (element is highlighted), if you press Locate, the application

automatically switches to one of the following:

³ the graph view: The application zooms in on the first event or fiber

section for which the status is “fail”.

³ the Trace Info. tab: The application highlights the row

corresponding to the first element (span loss, span length, or span

ORL) for which the status is “fail”.

³ You can press the Details button for further information on the

element having a “fail” status.

Note: Instead of pressing the Locate button, you can double-tap the element

having a “fail” status.

If you do not see any status (pass or fail), this probably means that no

threshold was selected (see Setting Pass/Fail Thresholds on page 247), or

that the only threshold that is selected is Fiber section attenuation, but the

fiber sections are hidden (see Customizing the Events Table on page 243).

To display the summary table:

From the main window, select the Summary tab.
