FTTdp networks using G.fast can complement the rollout of FTTH, especially in regions where the deployment of fiber inside the building is difficult. This article analyzes the main cost components of FTTdp networks with G.fast and the cost differences that can be achieved in comparison to FTTH networks. The two metrics employed in the article, the cost per home passed and the cost per home connected, were applied to six different geotypes that range from dense urban to rural scenarios. The results show that the cost per home passed of an FTTdp network with the distribution point located in the street is lower than the cost of FTTH. The cost per home connected for FTTdp is lower than that of FTTH for all of the scenarios studied. The cost reduction rates achieved by FTTdp networks are higher when employing a brownfield deployment scheme than when employing a greenfield deployment scheme.
