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.
Comsof supports that demand points can be supplied with a fixed cable-type, independent of the calculated fiber requirement. To do this, use the "Forced cable-type" attribute on the demand point form.
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.
