Understanding 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.
If you are viewing multiple measurements in the Cable view and the
elements present an anomaly (for example, the elements are not of the
same type or do not have the same threshold values), you will notice an
icon on the upper right-hand corner of the element instead.
Element 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.
You can see the details about the diagnostics in the Elements Table tab.
