Hybrid FTTC and FTTH Solution

© KEYMILE I Page 12

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
