Analyzing Traces and Events

Enabling or Disabling the Detection of Reflective Ends of Fiber
Enabling or Disabling the Detection of
Reflective Ends of Fiber
By default, the application stops the analysis as soon as there is too much
noise on a trace to ensure accurate measurements. However, you can
configure the application to search the “noisy” portion of the trace to
detect strong reflective events (such as those caused by UPC connectors)
and set the span end at this point.
Note: The detection of reflective ends of fiber is only performed when you test at
singlemode wavelengths.
Once you have selected the option, the detection will be performed
automatically on the next acquisitions.
If a trace was acquired without selecting the option first, you will have to
reanalyze the trace manually (for more information on trace reanalysis,
see Analyzing or Reanalyzing a Trace on page 155). When you reanalyze a
trace, to benefit from the option, you should select Reset span delimiter
positions.
The application will take into account the option only if there is a significant
reflective event located after the end of analysis.
