  1. A clear and balanced view on FTTH deployment costs K. Casier, S. Verbrugge, R. Meersman, D. Colle, M. Pickavet, P. Demeester

  2. A clear and balanced view on FTTH deployment costs

  3. A clear and balanced view on FTTH deployment costs

  4. Calculating the costs of a next generation access network

  5. Overview of the costs (Example Pt2MPt, semi urban)

  6. Zooming in on the CapEx

  7. Zooming in on the CapEx

  8. Trenching is extremely costlySo reduce this as much as possible

  9. Central Office Buried drop point Facade drop point Aerial drop point And reduce the total deployment length

  10. Central Office Fiber cable Buried drop point Facade drop point Aerial drop point By constructing a Steiner Tree NP-hard  heuristic techniques Interesting research topics Clustering & cherry picking Ring structures for resilience

  11. Finally there are also different fiber architectures for the access network

  12. The other parts of the physical deployment have a much smaller impact

  13. Using an alternative to trenching (here aerial) can save considerable Aerial 30% of customers 10% of the installation length

  14. Zooming in on the OpEx

  15. Zooming in on the OpEx

  16. Zooming in on the OpEx

  17. Service provisioning takes care of connecting the customer

  18. Service provisioning consists of 4 large parts 1 2 3

  19. Especially the equipment consumes a large part of the costs

  20. There is a trade-off between pre-installation and later installation

  21. Finally there is also the OpEx for keeping the network up and running continuous pricing and billing 1% 9% maintenance and repair marketing 9% customer equipment 38% operational planning 22% maintenance and repair maintenanceand repair inside plant outside plant 15% 6% 29

  22. So – We’ve shown an approach forcost breakdown and balanced (zooming) estimation

  23. So – We’ve shown an approach forcost breakdown and balanced (zooming) estimation • Deployment (70%) mainly trenching (80%)  optimized installation tree  cherry picking  alternative installation types

  24. So – We’ve shown an approach forcost breakdown and balanced (zooming) estimation • Service Provisioning (25%) mainly equipment ONU (65%) advantage of pre-installation  reduced trenching  early customer binding

  25. So – We’ve shown an approach forcost breakdown and balanced (zooming) estimation • Keep up & running (10%) mainly maintenance (60%)

  26. In the future we plan to … Proceed on this approach • Investigate trade-off between CapEx & OpEx • Model the cost-structure in more detail • Expand this approach to other technologies (e.g. wireless)
