  12. 12. Hybrid FTTC and FTTH Solution  Combine both technologies to get a profitable business case  An opportunistic deployment strategy reduces earth work  Providers can easily operate both technologies in parallel  One type of service provisioning  Same user identification and separation schemes  Unified IPTV platform  Same trouble shooting procedures  Provider can share investment with others  Open access on layer 2 I Page 12 © KEYMILE

  15. 15. Conclusion  Demand for bandwidth increases continuously  But: how to get the ROI?  Seek lowest investment path towards full FTTH deployment  Via direct combination of xDSL and fibre technologies during transition  Assure common topology, provisioning  Lowest costs due to opportunist and flexible ground work  Bandwidth growth for all I Page 15 © KEYMILE
