Drop layer

In this tab, you can define everything related to the building connection (drop).  

Strategy

Here you define whether or not there are to be clusters in the drop area, differentiated according to underground/Aerial.

If no drop clusters are to be generated for underground drops, please select “Seperate drop point (no clustering)”.

Drop Ducts 

This is where the duct types to be used in the drop area and their usages 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 duct affects their use and thus the optimization result.

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
Material/Labour Cost 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.

 

If existing empty ducts are to be included in the planning, the corresponding checkbox must be activated.

If you would like to provide additional microducts for the supply of the demand point for future requirements, you can control this via place additional spare ducts.

Drop Cables 

This is where the cable types to be used in the drop area and their handling 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
Cost Material/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 drop layer.

You have the option of defining overlays as a percentage or with a fixed value.

Drop Equipment 

If you want to have equipment planned in the drop point, something must be set here. The drop point is the point where the feeder trench meets the trench leading to the building (or the point where the microduct in the distribution duct is connected to the drop microduct). 

If equipment is to be created, the planner has the choice between drop box, overground drop box, closure, manhole and handhole.

The costs for the equipment are determined under the Costs entry.

For the equipment, identifiers can be assigned which can then be costed in a dedicated manner under Costs.

Note

If no equipment is to be created in the drop point, the entry must be deleted.
