First choose a cable type and definition. If no fitting cable definition exists, you can create one.
Usually name and number are generated automatically, but you can also define them yourself. Finally decide whether the cable should be added in a cable tray.
If you chose not to place the cable in a tray, you will be asked to define source and target room of the cable. You can carry over locations from source to target using >>.
Otherwise you will be asked to select the tray. If it does not exist yet, you can create it.
Finally an overview over the fibers in the newly created cable is shown.
Click Finish to add the cable.
