Analyzing Traces and Events

OTDR 139

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.

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 be

prompted to reanalyze the trace (for more information on trace reanalysis,

see Analyzing or Reanalyzing a Trace on page 134). 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.
