The FTTdp: the opportunities for deployment

New copper-based broadband technologies, such as G.fast, have prompted a debate about a new architecture for FTTx networks called fibre to the distribution point (FTTdp). This report assesses whether continuing improvements in copper technology make this necessary and where there might be a case for this new architecture.

About this report

Executive summary

The extensive capex required for FTTH deployments is problematic for operators because revenue is stagnating

FTTdp could enable telcos to keep pace with cable competitors while minimising capex



SuperVector/Vplus technology offers opportunities to considerably increase bandwidths from cabinet locations

G.fast performance is improving, but is constrained by the need to co-exist with VDSL

The performance of G.fast will improve in future, which could either delay or promote FTTdp roll-outs


FTTdp costs can be lower than FTTH and distribution point size is a key variable in the difference between the cost per home passed

Active equipment costs make the cost per home passed higher for FTTdp than for FTTC

FTTdp deployments cost much more than upgrading existing FTTC deployments

Using existing cabinet deployments offers the possibility of limiting the cost per connected home and lower opex than FTTdp

Reverse powering reduces costs for FTTdp, but existing cabinet deployments will still have the lowest powering costs

Case 1: The absence of legacy distribution points complicates the business case for FTTdp but does not necessarily render it impossible

Case 2: Operators can use existing manholes for FTTdp deployment even if they have to cut through the cables


Operators with longer sub loops could profitably deploy FTTdp architecture

FTTdp deployments are particularly viable in countries where MDU penetration is low, but there are caveats

Australia, Canada, Switzerland and the USA are highly promising markets for FTTdp architecture
