MDUs, small cell sites and other types of demand

By default under most architectures, every address point uploaded into FOND will receive a single split fibre.

In order to get more than one fibre, you can edit the Demand field of an address. 


When that Demand value is smaller than the number of ports on the T1 Closure in your chosen architecture, the address will receive the number of drops equal to that value. When Demand is larger than the number of ports on the T1 Closure, FOND makes the following assumptions for a 1:32 split ratio architecture:

  • Leave unsplit fibre at this location
  • Leave 1 fibre per 30 units

So if you have an address point with Demand = 101, FOND will drop 4 unsplit fibres at that location.

For most 3 tiered architectures, the Demand value is intended to represent the number of homes in an apartment under a 1:32 split architecture. However, you can take advantage of this for small cell sites, traffic lights, or any other sort of demand you can think of. These sorts of demand typically define their requirements in terms of how many fibres they need. To tell FOND to drop X fibres at some location, simply set the demand value to X*30. E.g if you have a set of small cell sites that each need 1 fibre, set the Demand value of each of those features to be equal to 30.

Backhaul architectures

You can also request a special 'backhaul' architecture where the Demand value is in a one to one relationship with the number of fibres.

In the GIF below, I select the Tier 3 cable to show that it's currently allocating 12 fibres to a point with a Demand value of 12. I then update that to 110 and hit 'update design'.



In the image below, you can see the result of that is that FOND serves that point with a 144 cable - the smallest cable in the architecture capable of serving that point.
