VDSL2 meets Digital Agenda Requirements
Bonding ITU-T Standard (G.998.1 & G.998.2) approved in 2005
50Mbps @1 000m 100Mbps@500m
Coverage or bandwidth is doubled with 2 pairs
Coverage or bandwidth significantly improved

Distance: between 100m & 800m Bandwidth Gain @ 400m : +50%
Distance: less than 100m Bandwidth Gain @100m: +70%

Vectoring
Up to 80% gains
BW with Vectoring
With increased bandwidth, operators can provide a broader variety of services to end-users, thus increasing revenues%
Increased Coverage: Less central offices or street cabinets needed Higher Power efficiency : power consumption per port per Mbps is decreased by 16% Lower cost per Mbps offered by VDSL2 with vectoring compared to VDSL2 alone Preserved investment: System-level vectoring avoids to change line cards and control cards No rewiring needed: the stronger disturbers are managed automatically by System-level vectoring

Challenges & Opportunities of NG DSL Technologies
Availability of multiple pairs for bonding G.Fast is not standarized yet
Comply to the Digital Agenda requirements: 30 Mbps for all by 2020 Is VDSL2 approved and allowed by NRAs? Impact of EC public consultation making copper less attractive with lower wholesale access price

Vectoring used by 2 operators in SLU is either not appropriate or difficult to achieve Legacy ADSL can coexist with Vectored VDSL making SLU feasible with an average of 40% Bandwidth gain
Pay as you grow approach for Alternative operators limiting their initial investments All operators get maximized bandwidth and increased revenues with New Generation DSL

Bandwidth Challenge
Benefits & Challenges of New Generation DSL Technologies
Benefits & Challenges of XG-PON1
Benefits & Challenges of NG-PON2
Leverages xPON Experience Lower Power Consumption
Benefits of XG-PON1
Higher OPEX savings with lower power consumption levels Lower CAPEX offered by economies of scale Same protocol used for time synchronization for mobile backhaul for GPON & XG-PON1
Coexistence with GPON
No overlaps in wavelengths No change in existing Optical Data Nodes No change in existing GPON ONUs Possible coexistence leads to preserved initial investments
Higher Reach
Up to 40km coverage with design based on APD technology Reduced TCO with less OLTs needed
XG-PON1 networks offer lower consumption levels compared to VDSL and P2P technologies
FTTH Roll-out Costs
European Commission Funding
3G/LTE Mobile Backhauling
3G/LTE networks Offload
Challenges & Opportunities of XG-PON1
Launch of the pilot phase of the “Europe 2020 Project Bond Initiative” in the period 2012-2013: 230 million euros “Connecting Europe Facility” funding plan : 9.2 billion euros between 2014 & 2020 (at least 7 billion euros could be used for the infrastructures)
FTTH cost is impacted by civil works and VDSL2 is 5 times cheaper to roll-out Up to 270 billion Euros of investment are required to bring fast broadband to all households by 2020 in Europe
XG-PON1 access 3G NodeB or LTE eNodeB in FTTH deployed area to realize FMC
XG-PON1+WLAN offloading for 3G mobile data services Reduce wireless network congestion
Global Cost for Nationwide Coverage in UK (Source: Analysys Mason)
Mobile Usage is Mostly @Home
XG-PON1 is Key for Wi-Fi Offload Strategies
Wifi Usage is Gaining Momemtum
Opportunities
Benefits & Challenges
Wi-Fi usage multiplied by 3 between 2010 & 2011 over fix subscriptions France (Orange) Among 1.5 million tablets sold in France in 2011, only 23% have a 3G connection mostly not used by customers: over 77% of the Tablet customers use Wi-Fi (GFK study ) 63% of traffic generated by smart phones and tablets will transfer onto the fixed network via Wi-Fi and femtocells by 2015 (Juniper Research - April 2011)
Mobile & fix ops: offload 3G/LTE mobile traffic on the fix network with new Wi-Fi APs outside the home or with existing Wifi enabled ONUs Fix ops: Leverage street cabinets with new Wi-Fi APs or leverage existing Wifi ONUs: Increase Revenues
Benefits Wi-Fi offload will reduce the traffic on the 3G/LTE network by using FTTH network XG-PON1 provides up to 10Gbps and is ready for « high speed » Wifi (300Mbps – 802.11n)
Challenges Seamless authentication procedures have to be put in place Wi-Fi is not a 3GPP standard & an unlicenced spectrum New 5Ghz band has to be available on all devices

Challenges
Benefits & Challenges of NG-PON2
Unbundling Friendly: Open Access: each operator can use its own wavelength to offer dedicated services to end-users.
Lower TCO: TWDM PON leverages XG-PON1 OFDM PON can use cheaper & programmable components TWDM PON & WDM PON: tunable colorless lasers in ONUs are easier to install and maintain
Higher Revenues: Higher Bandwidth = Increased Revenues Dynamic allocation of subcarriers with OFDM PON optimizes the bandwidth needs by each ONUs
Higher Security Unshared symmetrical bandwidth with WDM PON
Time to market: Standard expected in the 2013-2015+ time frame & commercial deployments are expected to start after 2018. Coherent detection for HD WDM PON requires a long industrialization period
Unbundling: Regulation to be defined at European & local level
Power consumption Medium to high prospective cost
Smooth Evolution Benefits
Coexistence with existing ODN & ONUs offering preserved investments
Higher Capacity: TWDM PON: between 100Mbps & 1Gbps per user WDM PON: 1Gbps/ 1Gbps dedicated bandwidth
Higher Reach: TWDM PON / OFDM PON : Up to 40km WDM PON: Up to 100km
Higher density: Up to 1 024 users/port with High Density WDM-PON solution
