Today
Small capacity – 1-8 ports / device
Reverse powered from End User premises
GPON backhaul (like Fibre NTD)
VDSL2 over existing copper lead-in into premises (< 100m) – 100/40
Future
Other backhaul technologies (P2P, WMDPON, NGPON2)
Faster copper technologies – optimised for short copper runs (i.e. VDSL2 30a, G.FAST)
Reverse power supply integrated into CPE

4. Problem: Blocked LIC in FTTP areas
Problem statement
Approx. 10% of lead in conduits are ‘blocked’ in FTTP areas
This includes direct buried copper lead-ins
Current solution: bulk and build drop program
Impacts
Cost per prem of LIC build - $991 (bulk drop) or $1291 (build drop)
Delay to providing service
Poor End User experience
Time and effort for installation

Re-use existing copper lead-in to deliver VDSL2 service
Very short copper - so 100/40 achievable
No shared cables – no need for vectoring
Improve performance further with VDSL 30a or V+
Upgradable to G.fast

7. Other FTTdp applications
Full FTTdp area; FTTP without lead-in & in-premises costs
FTTN infill
Small cluster of long (>1.2km / 50dB) copper loops
Augmenting FTTN Port capacity
Underutilised micro-node alternative
Bandwidth on demand (> 25/5 Mbps)
Interim service while FTTP is connected
Small FTTB (wall mount 1P or pit-mount multi-port DPU)
“Fibre to the door”
HFC infill (where DFN and LFN is cost effective)

FTTdp fulfilment
FTTdp unit very similar activation to Fibre NTD
Re-use existing Fibre NTD activation IT
Some fulfilment changes due to VDSL2 interface
Bypass mode:
Install & pre-activate in OSS
Original service remains connected until reverse power is applied
When End User applies reverse power FTTdp comes online and takes over lead-in

12. Recommendation & Next Steps
Proceed with FTTdp solution development in CTO
Establish small FTTdp capability ahead of G.FAST
Encourage development in vendor solutions to NBN Co requirements:
Small size (fit in Telstra P2 & P3 lead-in pits)
Cost per port
VDSL2 only
Next Steps
Assess use of small FTTdp for whole of DA against other access options
Combine with LFN re-architecture for MTM & lower cost
Reduced civil works (avoiding pit & pipe remediation)
Plan evolution to G.FAST
