FTTH architecture:P2P, an up-to-datereassessment Ermanno BerrutoWIND Telecomunicazioni S.p.A. FTTH Conference 2011 Milan, 9th-10th February 2011
Agenda• Copper network in Italy: LLU Success Story• Fiber optic unbundling in FTTH• P2P Architecture• FTTH Business Issues• Conclusions - Page 2 -
Copper network in Italy: LLU Success StoryThe Unbundling model used with the classical copper accessnetwork has been a case of great success in opening the accessnetwork and has allowed great development of competition andcreated great advantages for the consumers.Copper Network is unique as: electricity distribution motorway railway sewers water ducts ………Why not FTTH? - Page 3 -
Fiber optic unbundling in FTTHPoint to point architecture, one fiber for user from the exchange to the home.The fiber optic unbundling can be provided at the exchange side.Solution is similar to copper unbundling. Different Same Access Infrastructure Model MDF Operator 1P2P Access Node Operator 2 Access NodeGPON Operator 3 Splitter Central Office - Page 4 -
P2P Architecture A Future Proof Network Maximum flexibility and ease in passing from one operator to another Technology agnostic (the access network is single passive fibre that can support any technology such as ethernet, GPON, etc.) Symmetric services Zero touch: no further infrastructure up-grade Low maintenance cost - Page 5 -
P2P ArchitectureP2P needs a lot of fibers but: New micro-cables technologies allow higher existing infrastructure reuse (not only Telco) New digging technique make easier new infrastructure development (micro trench, one day dig…)P2P needs space in Central office but: New High density Optical Distribution Frame allows to manage up to 10k fibers in about 30-40 m2 No need of thousands of cabinets installed in curb or building - Page 6 -
New technologies to support Fibre ImplementationNo Dig Perforation with georadar Microtubes Yesterday Today Underground Compact Junctions - Page 7 -
New technologies to support Fibre Implementation CablesMini cables with up-to 144 fibres with only 7.8 mm diameter - Page 8 -
New technologies to support Fibre Implementation Digging TechnologiesIn alternative to traditional fibre trench excavation various new low impactexcavation ( 5 cm x 30 cm ) alternatives are available . Microtrenches One day Dig continous cicle using small machines requiring one day work - Page 9 -
New technologies in support to Fibre ImplementationHigh Density Optical Distribution Frames are becoming available In Rome we are testing jointly withFor example : Fastweb and Vodafone an Optical distribution Frame for 10k fiber withApplication Footprint: max. 1536-ports/frame 36m2 footprint in an LLU scenarioApplication Density: max. 3353-ports/m² - Page 10 -
FTTH Business Issues FTTH has long term viability Pay back investment not less than 7-10 years Crucial issue for credible business model is Copper Total Replacement. Copper fees totally transferred to the fiber network. Othersolutions for enhancing the FTTH business model can be found by introducing new broadband services and by decreasing the cost per home passed (100% take rate) - Page 11 -
FTTH Business Issues Many studies show that one P2P infrastructure can optimize the global investment and the TCO The total amount of available money is limited. Instead of overlapping several networks, the overall coverage could be enlarged with a single network, using the same amount of money Overlapping NO-Overlapping - Page 12 -
Pure P2P cost VS Multi-GPON Memorandum Of Understanding Italia Digitale Sviluppo dell’infrastruttura per Reti a Banda Ultra Larga Roma, 10 novembre 2010A MOU has been undersigned between Operators andthe Government who has promoted it , in order tostimulate the development of Ultra Broad band Networksin Italy.From the evaluations carried out within the MOU, it canbe deduced that the additional capex needed toimplement a fully P2P architecture would bearound 10% vs multi-GPON - Page 14 -
P2P +23% vs Single GPON, but Multi-GPON +47% vs P2P Δ +47% Δ +23% Single Multi- GPON GPON P2PAverage Capex difference between Base Case (Std GPON) and Exchange Flexi Point(1 fiber per user from the Exchange to the Household, PtP like) is about 23% - Page 15 -
Multi-GPON: the worst scenario also from Opex point of viewSingle P2P Multi-GPON GPON Single P2P Multi- GPON GPON - Page 16 -
P2P represents a viable solution in high take rate area and small to medium CO - Page 17 -
Conclusion The opportunity is to build only one fiber agnostic infrastructure (P2P) with copper total replacement in order to: Avoid duplication Enlarge as much as possible FTTH area Enable services ecosystem and Country economy Reduce TCO and guarantee future profness Infrastructure could be a premium only in start-up phase Lesson Learned in Mobile Tower is clear: now each operator tries to share sites as much as possible - Page 18 -
