Comparing OTDR Traces

The trace overlay function lets you see two OTDR traces at
the same time. This lets you do the following:
•
Compare a link's current trace with a past trace to see if
the link has changed.
•
Compare traces from links in the same run to check for
differences.
To compare two traces, do the following:
