Analyzing Traces and Events

96 OTDR

Summary Tab

For each wavelength, the summary tab gives the span loss, the span ORL

values, and the global status of the results:

 pass: no results exceed the thresholds

 fail: at least one result exceeds the thresholds

 unknown: no threshold is configured or a span value (length, loss,

ORL) is not available

The span length (distance between span start and span end) is also

displayed, except if a continuous fiber is detected for all wavelengths.

Note: In the summary tab, you can tap to display the current trace only.

When the current trace is displayed (main or reference trace), you can also

switch from one wavelength to another. When the current trace is not

displayed, all wavelengths appear.
