  1. 1. Promising Next Gen PON Networks FTTH Council Europe 2010 Conference Feb 25th, 2010 By Christophe de Saint-Martin Director of Marketing for Western Europe
  2. 2. Agenda Market Drivers Next Gen PON Networks Benefits Next Gen PON Networks Challenges Evolution paths to Next Gen PON
  3. 3. Market Challenges for Operators Limited Bandwidth Increased Costs New web-based services drive Operators want to save money by reducing complexity bandwidth demand in the access of managing multiple networks LTE mobile networks need high Traditional transport technologies are not cost effective bandwidth for backhaul (PDH, SDH) 50% of the data traffic on AT&T’s Fixed & Mobile convergence will reduce network costs mobile backhaul network is iPhone- generated, despite the fact that only a few million of their 78 million cellular subscribers are iPhone users Flat Revenues Gap between traffic & ARPU Operators are looking for Increased bandwidth requirements but revenues solutions offering growth is slow Traffic Higher Performance Gap between traffic Gap between Lower cost Gap between traffic traffic and revenue and revenue Improve customer increases satisfaction Revenues Offer new services to increase revenues Voice Dominant Data Dominant Fixed & Mobile convergence
  4. 4. Towards More Symmetric & Higher Bandwidth “Legacy” xDSL is bandwidth limited and offers asymmetric traffic with high downstream bandwidth and limited upstream bandwidth More bandwidth symmetry is needed TeliaSonera considers that in 2010 “typical” digital home, up to 66 Mbps (DS) & 27 Mbps (US) will be needed. Online gaming will “balance” the traffic bringing it back to symmetry.. Some operators even notice higher traffic in upstream than in downstream In the case of Hong Kong Broadband, the upstream traffic is 3 times higher compared to the downstream traffic explained by the successful usage of video cameras uploads Balanced traffic Uplink traffic is 3 times higher Digital home 2010 bandwidth needs Digital TV bandwidth Hong Kong Broadband (TeliaSonera) needs traffic Higher Symmetric Bandwidth is and will be Needed
  5. 5. Today and Tomorrow Bandwidth Requirements Web surfing Video conferencing, Surveillance Gaming, Learning Web-Hosting Residential only Files sharing Residential & Business Video upload/download Mobile Backhaul Network hosted applications & Storage FTTH Technologies 2D HDTV 3D TV DSL Technologies 2G/3G ?

  7. 7. What are Next Gen PON Key Benefits? Increased Capacity Increased Coverage 10 2.5-10 Gbps Gbps Long Next Gen Downstream Upstream TDM CO VDSL2 P2P Reach WDM PON TDM PON PON 1.25- 2.5 1.25 100 100 Mbps Gbps Mbps Gbps VDSL2 EPON/ Next Gen VDSL2 EPON/ Next Gen Kms GPON PON 50 Mbps GPON PON 0.5 10 20/30 60 100 Increased bandwidth will offer new Increased Coverage will reduce the number services and will increase revenues of Central offices needed in rural areas thus Higher ports density with higher splitter offering OPEX & CAPEX savings ratio will offer more subscribers per central Operators can close end remove exchanges office thus reducing OPEX & CAPEX that will be not necessary: France Telecom could close 95% of its rural COs in Western France with Long Reach Next Gen PON Networks will Reduce TCO and Increase Revenues
  8. 8. What are Next Gen PON Key Benefits? Green Network Elements Lower cost per Mbps Network Element W/port/subs 58% 82% Green 3-5 Technology 1.8-2.5 1.8-2.5 1.8-2.5 <0.3 <0.1 EPON 10G-EPON GPON XGPON1 VDSL P2P GPON Next Gen Note: Cost per Mbps based on 32 connected subscribers (OLT +ONT CAPEX) DSLAM Switch OLT PON OLT (*) (**) Next Gen PON Optics costs are higher due to higher performance levels xPON networks offers lower consumption The cost of 10G-EPON will decrease compared levels compared to VDSL and P2P technologies to EPON: In 2012, the cost per Mbps of 10G- leading to OPEX savings EPON will be more than 80% lower than EPON Next Gen PON OLTs will offer additional The cost of XGPON1 will decrease compared to savings based on green innovations and higher GPON: In 2012, the cost per Mbps of XGPON1 split ratio will be more than 58% lower than GPON (*) 64 subscribers Next Gen PON Networks will Reduce TCO and Increase (*) 128 subscribers Revenues
  9. 9. Benefits of Unified xPON Access Platform Reduced CAPEX Reduced OPEX Cost efficient industrial chain : Green Technology Unified chipsets & modules for different xPON Lower power consumption with newest design & technologies innovative features Flexible Platform Optimized OAM Common Chassis & backplane for GPON / EPON / Unified Operation & Maintenance for different P2P/ 10GE PON / XG-PON 1/ WDM-PON cards xPON technologies Next Gen PON Readiness Lower upgrade costs: Only 1 new module is needed for the upgrade to 10G-EPON (or XG-PON1 or WDM- PON) compared to a traditional design Only 1 new module is needed Only 1 new module is needed GPON P2P GPON P2P 10G-EPON 10G- P2P 10G-EPON 10G- WDM PON WDM PON 10G-EPON 10G- Step1: GPON /P2P Step 2: GPON Step3: 10G-EPON Step 4: 10G-EPON /10G-EPON/P2P /P2P/WDM PON /WDM PON Unified xPON Platform Reduces OPEX & CAPEX and Preserves Initial Investments

  12. 12. Which Challenges for Current PON Networks? Regulatory Framework Cost per Subscriber A “one size fits all” regulation is not possible in High cost to deploy PON networks compared to VDSL Europe with 70-80% for civil works Infrabased competition (“passive access”) is the In Europe, 81% of the FTTH networks are using P2P prefered solution encouraged by EC technology Unbundling is only possible with point to point GPON is a more cost effective approach technologies like VDSL, Ethernet P2P and WDM than P2P especially in low density areas PON Duct sharing will decrease the cost of civil works Recent regulatory decisions in Big 5 nations should speed-up FTTx roll-outs Un Duct bundling Cost per home passed in an urban setting sharing Active Line Access VDSL2 Bitstream P2P PON Sources: Idate / Ventura Team
  13. 13. Green Industry Challenges Global Warming challenge The communication industry amounts to 2% of global CO2 emission, according to Gartner’s report Operators are addressing this issue & ambition to improve their network energy efficiency: BT: aims to reduced emissions by 80% before 2016 Technology Innovations are expected and necessary Equipment vendors have to increase power savings with new hardware design and Software features New Chipsets Automatic Switch off PCB Design Adjustable Speed Fan Innovation is Needed to Decrease Power Consumption and Preserve Lower TCO
