    Evaluating FTTx as the next fibre access opportunity for Colt Evaluating FTTx as the next fibre access opportunity for Colt Presentation Transcript

    • Contents 1 2 Managing a highly multi-level fragmented situation in EU 3 2 Introducing the two distinct cases: off-net and on-net Reviewing candidate active technologies
    • Colt – Europe’s information delivery platform • Connecting 22 countries, 39 metro networks and >150 cities • 20 data centres and 19,000 connected buildings • 44,000km EU high capacity long distance network, 27,000km transatlantic 3
    • The long story of fibre access at Colt • Launch of Colt business in 1993 in London AN node – Followed by Frankfurt in 1995 and Paris in 1996 • Fibre as the mainstream access CPE since the beginning – Using shared customer ring topology and SDH, EoSDH then native Ethernet as active technologies • Highly resilient access architecture – Dual-homed access rings with geographical node diversity wherever practical building on Carrier Ethernet introduced in 2007 4 1G & 10G fibre access metro core
    • The long story of fibre access at Colt • Launch of Colt business in 1993 in London AN node – Followed by Frankfurt in 1995 and Paris in 1996 • Fibre as the mainstream access CPE since the beginning – Using shared customer ring topology and SDH, EoSDH then native Ethernet as active technologies • Highly resilient access architecture – Dual-homed access rings with geographical node diversity wherever practical building on Carrier Ethernet introduced in 2007 and how will Where 5 1G & 10G fibre access metro core FTTx come into play?
    • The off-net case today • The off-net city profile – PoP with network equipment – No fibre access medium (nor copper) – Leased bit-stream access with E-NNI delivery at the PoP OLO bit-stream access PoP AN 1G & 10G E-NNI Colt demarcation (optional) 6 Colt core
    • The off-net case today • The off-net city profile – PoP with network equipment – No fibre access medium (nor copper) – Leased bit-stream access with E-NNI delivery at the PoP OLO bit-stream access PoP AN 1G & 10G E-NNI 75% of all cities where Colt operates! Colt core Colt demarcation (optional) 7
    • The off-net case in FTTx time: an opportunity • Leased dark fibre as the main access – Keep bit-stream as complementary access to cope with coverage & pricing/ROI issues • The FTTx promises – Better control of service characteristics (BW, QoS) – Enabler of very high-speed services (from sub-1G up) OLO bit-stream access PoP AN 1G & 10G E-NNI Colt demarcation (optional) Colt demarcation 8 Colt core OLO fibre plant
    • The on-net case today • The on-net city profile – MAN city with Colt-owned & operated fibre as the main access medium • Leased copper (ULL) as complementary access to reach off-net locations • Leased bit-stream access as the last resort – Multiple nodes in the largest cities (LON, PAR, FRA, BRU, ZRH, etc.) (x1…5) 1 2 EFM DSL PTT copper plant AN PTT CO (x10…50) Colt metro core CPE 1G & 10G E-NNI 3 9 Colt node Colt demarcation (optional) OLO bit-stream access
    • The on-net case in FTTx time: a threat for DSL • DSL revenues highly exposed over time – Customers more attracted by fibre with performance outperforming copper’s • FTTx gradually replacing copper as second-choice access 2 Colt demarcation EFM DSL (x1…5) OLO fibre plant 1 PTT copper plant AN PTT CO (x10…50) Colt metro core CPE 1G & 10G E-NNI 3 10 Colt node Colt demarcation (optional) OLO bit-stream access
    • A highly multi-level fragmented situation in EU High risk of heterogeneous architectures & operating models • Commercial offering – Slow building up process with few trial opportunities so far in FR, CH and NL – Various approaches for the pricing model commercially structured for P2P or P2MP – Missing comprehensive business-targeted SLAs (protection, MTTRepair, MTTRespond) – Development of B2B systems needed for fibre eligibility check and automation • Regulatory environment – Managed locally by national regulatory authorities – Variety of different rules: duct vs. fibre sharing, dense vs. non dense area, etc. – B2B market most often not the primary focus • Work in progress at all levels • Business development complexity and challenges for service providers with multi-country presence 11
    • Candidate active technologies (fibre-based) Technology Cons • Cost competitive • Perfect fit for residential users • Proven • Security concern (broadcast) • Efficient fibre use (down to the MP) GPON Pros • Optical reach (power splitter) • Uncertain per-customer BW management (shared medium & TDM) P2P • Perfect fit for business customers • Fibre greedy (CO-MP section) • Available as a straightforward topological variant of existing metro Ethernet network WDM PON • Optimum reach with no splitter • Perfect fit for business customers • Efficient fibre use (down to the MP) • No standard yet (NG-PON2 went for hybrid TWDM) • Vendors’ proprietary solutions • Low volume hence more expensive 12
    • Candidate active technologies (fibre-based) Technology Cons • Cost competitive • Perfect fit for residential users • Proven • Security concern (broadcast) • Efficient fibre use (down to the MP) GPON Pros • Optical reach (power splitter) • Uncertain per-customer BW P2P • • • P2P is the winner today management (shared medium & TDM) Perfect fit for business customers WDM • Fibre greedybe watched • Progress of true PON will (CO-MP section) Available as a straightforward topological • GPON is not seen good for business customers variant of existing metro Ethernet network WDM PON • Optimum reach with no splitter • Perfect fit for business customers • Efficient fibre use (down to the MP) • No standard yet (NG-PON2 went for hybrid TWDM) • Vendors’ proprietary solutions • Low volume hence more expensive 13
    • What about VDSL2 copper in the interim? • Colt ULL deployment model – In selected cities (100+) and at the CO level only – Only the symmetrical EFM DSL flavour (G.SHDSL) but no ADSL2+/VDSL2 – Historically lack of business case for deeper deployment at street level – Uncertain driver for a possible change given the now (slowly) emerging FTTx • Vectoring and regulatory environment – VDSL2 performance limitation of BW vs. reach significantly mitigated with vectoring – However subject to all VDSL2 lines in the cable being controlled by one operator – New SLU model of just one VDSL2 operator offering bit-stream access to other operators • At the very best only a niche application (CO level) • Introduction only at the CO level even arguable 14
    • : P2P dark fibre : Ethernet AN & CPE Target design • FTTx seamlessly integrated into Colt Modular Multi-Service Platform (M-MSP) – Single CPE and delivery process for FTTx and on-net accesses • FTTx as per P2P dark fibre off-net city 2 Colt demarcation on-net city OLO fibre plant (x10…50) PTT CO PTT copper plant EFM DSL 3 Colt demarcation (optional) (x1…5) AN PoP 1G & 10G E-NNI AN OLO bit-stream access node OLO fibre plant 1 15 Colt demarcation (optional) 2 CPE OLO bit-stream access 1G & 10G E-NNI Colt metro core Colt demarcation 1
    • Summary • P2P as the selected FTTx option to support Colt business customers – Interest in WDM PON technology once standardised and matured • FTTx as a simple access variant of Modular MSP platform – Easy and quick integration at network, system and process levels • FTTx as the perfect off-net option enabling Small Cells and LTE/LTE-A – DSL and wireless access likely to face hard time BW and reachability wise To be followed over the next couple of years as FTTx operators offers in EU are just and slowly taking up in difficult economies 16
