Understanding the Link View
The pass/fail status also depends on the threshold values specified. The
link overview representing all the elements discovered on the link is
described below.

Length of the measured link: Length of the measured link excluding
the launch and receive fibers.

Selected element: Rectangle representing the selected element.

Visible region: The colored background represent the visible region in
the link composition view.

Beginning of the link: Beginning of the link under test.

End of the link: End of the link under test.
Elements before A and after B are referred to as out-of-span elements.
Elements out of the span are not tested for pass/fail status, but can have
diagnostics on them. If the launch fiber is not defined, the element marked
as "A" will not be tested for pass/fail and if the receive fiber is not defined,
the element marked as "B" will not be tested for pass/fail.
