Demand layer

In the Demand layer tab, you define the fiber requirement per demand unit, building and layer point. You can differentiate between active and spare fiber requirements as well as between PON or P2P technology.


Fiber requirement per demand unit or building


Which PON or P2P demand units are connected is defined in the advanced settings and can be changed there.

The default setting is: 



For buildings (demand point), both PON and P2P fibers can be requested.

If you have assigned a demand type to demand points, separate rules can be defined by demand type – both for buildings and for demand units.

Use the + icon to create another row for the corresponding identifier.

Fibers per Aggregate Point 


Here, you define the fiber requirement for a given structure. The “Layer” column is used to set the network layer for which the fiber requirement is requested. For example: With “Distribution”, the fiber requirement is calculated in the feeder-cable layer.

If you have assigned a structure type to the structure, you can define a separate rule for this. Use the + icon to manually create another entry in the rules.

To import the structure types used, use the “Import Equipment Types with Demand” button.


In “Spare fibers stop in”, you define how far the spare fibers are drawn in the network. The “Never Terminate” option means that the spare fibers are laid up to the POP and placed on the passive equipment OMDF. This means that the spare fibers are also taken into account for the dimensions of the POPs.


Demand Costs


Here you can define the costs for active and passive terminating equipment in the building or per connection (households).
