A cable is a group of fibers. It contains physical property information and logical data for the cable itself and for each of the fibers in the group. The fibers represent the cores and their parameters. Use an imported datatable or define the cable's core parameters to add information or parameters associated with individual cores in the group.

You can use a predefined cable or create one by bundling cores. When you use a predefined cable, you must first define its cores, shield, and decorations in the catalog and then manually route it. New cores and cable decorations are then drawn automatically. A predefined cable is most useful when routing between connectors. To create a cable by bundling cores, instance the cores individually, select and bundle them together, and then manually apply the cable decorations. A bundled core cable is used when creating harnesses or creating cables on an ad-hoc basis.
