Diagnostics
This section explains the diagnostics feature available in the intelligent
Optical Link Mapper application.
Diagnostics are used to provide additional information about detected
problems or ambiguous measurement situations, such as root cause
possibilities for the fail status of a link element. The diagnostics provide
help to troubleshoot faulty connectors, understand why link elements are
tagged as fail or unknown, indicate unexpected instrument or test
conditions and so forth.
Link elements with an associated diagnostic are marked with an icon,
and the diagnostics are displayed in the Element tab. More than one
diagnostic can be associated with any given element.
The following section describes the Element diagnostics.
Element Diagnostics
Elements diagnostics are associated with specific link elements issues.
Each failed link element will have associated diagnostics to assist in
troubleshooting. Some elements, such as macrobends, will have
associated diagnostics even with a pass status.
Power Meter Results
Power meter results are displayed in the OPM and PPM table. For more
details, see Power Meter Results on page 97.
