Customizing the Elements Table Tab
Adding Elements
The application allows you to add elements in iOLM and iOLM Bidir files in
the link view by selecting any element or section.
You can add elements in both the Fiber and Cable views as well as the
Elements Table tab. Adding an element to the cable (whether you do it in
Cable view, or on the cable at the top of the Fiber view) adds it to all of the
fibers. You can also take one element from one fiber and add it to the other
fibers.
The added element supports the following scenarios depending on the
distance or position of the element:

The new element is added in a section of the link between two existing
elements.

The new element is added as a sub element in existing element group.

The new element is added as a sub element to a single element to
create a new element group.
Note: You cannot add any element before Element A or after Element B.
Note: You cannot add splitters on multimode or bidirectional measurements.
