intelligent Optical Link Mapper 115
Link View
Each sub-element is directly displayed as if they were normal elements.
See Link Composition on page 111 for more details on elements.
Note: For grouped elements, some values may not be available individually but
are available at the group level such as loss and reflectance.
Note: If some elements are grouped then the total group loss value is compared
with the addition of the thresholds defined for the individual elements in
group. If the total group loss value is greater than the addition of the
thresholds defined for the individual elements in group, the element will
show a fail status.
You can individually select grouped elements as any other standalone
element.
When elements are grouped at the beginning of the link, icon A is
displayed on one of the sub-elements.
When elements are grouped at the end of the link, icon B is displayed on
one of the sub-elements.
