BackBone
The calculation of the backbone layer can be activated via the check box.
Specification of the maximum homes defines the size of the backbone cluster.
Strategy
This is where you define the planning strategy at the backbone layer.
You can choose between direct and shared cable.
The maximum distance for the clusters is a soft planning parameter and defines the distance between POP and backbone point.
Various options are available for positioning the backbone point.
If you want to specify the backbone point for an input cluster, this must be recorded as an input layer point in the project.
BackBone Ducts
This is where the duct types available for planning in the backbone area and their handlings are defined. Multiple entries can be defined. Depending on the fiber requirements of the POP, the corresponding duct type is selected. One microduct per cable is required. Note that the cost per duct affects their use and thus the optimization result. Another duct type can be created at any time using the “+” icon.
Explanation of the column headers
| Total | Total number of microducts |
| Reserved | Number of microducts to be reserved from the total, i.e., not to be used |
| Materials/Labour | Costs per meter |
| Duct Type |
Conventional → if it is a single microduct Microduct composite → used in bundles |
| Outer diameter |
The outer diameter can be entered here. |
| Identifier |
The name of the defined duct type can be entered here. This information is important when exporting to NET Engineering. |
Use the check boxes to further specify the rules when planning the Feeder layer
Define what is set and when if the blowing distance is exceeded. Possible structures are a handhole, manhole or cabinet.
If existing empty ducts are to be included in the planning, the corresponding check box must be activated.
If a layer point at the backbone layer is to be reached by additional cables in the future, the number of cables must be communicated. Based on this quantity, the required number of empty ducts is provided.
BackBone Cables
This is where the cable types to be used in the backbone area and their handlings are defined. Multiple entries can be defined. Depending on the fiber requirement and the defined cable types, the corresponding duct type is then selected. One microduct per cable is required. Note that the cost per cable affects their use and thus the optimization result.
Explanation of the column headers
| Fibers per Cable | Total | Total number of fibers |
| Reserved | Number of fibers to be reserved from the total, i.e., not to be used | |
| Fibers per Bundle | Total | Number of fibers per bundle |
| Reserved | of which bundles to be reserved | |
| Costs | Materials/Labour | Costs per meter |
| Drum length | Drum length | |
| Cable Type | Underground or Aerial | |
| Outer diameter |
The outer diameter can be entered here. |

| Identifier |
The name of the defined cable type can be entered here. This information is important when exporting to NET Engineering. |
Use the check boxes to further specify the rules when planning the backbone layer.
You have the option of defining overlays as a percentage or with a fixed value.
