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
High Density FTTC, FTTH rollout: 384 FTTC (VDSL) Ports and 240 FTTH Ports

480 optical Ethernet ports in a 4 HU shelf
Embedded WDM for embedded CATV RF overlay included
1.6 W per port – for 100 Mbps or 1Gbps
Conclusion
© KEYMILE I Page 15
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
