Link Groups
Link elements will be displayed as groups when the iOLM analysis detects
several link elements that are too close to one another to be independently
characterized. When this occurs, as much information as possible will be
displayed for each individual sub-element. The pass/fail status is applied to
each sub-element whenever possible, and a global status is also displayed
for the group.
Groups can also be displayed when a link element (such as a splitter) is
found to have wavelength dependant loss. In that case, the link element is
grouped with a macrobend element. In this particular case, there might not
be a physical macrobend next to the link element, but the macrobend icon
is used to highlight the presence of the wavelength dependant loss.
When elements are grouped, the group loss and group reflectance value is
also displayed in the Elements tab.
The grouped elements are described below.
