  • 1. THE SKY IS THE LIMIT WHAT TO EXPECT NEXT ? Michael Peeters, Wireline CTO FTTH Council München, February 2012v1 COPYRIGHT © 2011 ALCATEL-LUCENT. ALL RIGHTS RESERVED. ALCATEL-LUCENT — INTERNAL PROPRIETARY — USE PURSUANT TO COMPANY INSTRUCTION
  • 2. THE SKY IS THE LIMIT BECAUSE WE CANNOT SEE BEYOND THE HORIZON The 3 things we expect will drive technology 1.Sharing the cost 2.Saturated bandwidth demand 3.Flexibility, but not at any costv COPYRIGHT © 2011 ALCATEL-LUCENT.

FLEXIBILITYIN COST ALLOCATION PTP PON• Favored if Figure of Merit is lowest cost per • Favored if Figure of Merit is lowest cost per dedicated Mb/s subscriber• Valid for smaller deployments with short • Favored for higher peak bandwidths loops • Valid for all deployments • Strongly preferred for large COs, longer loops Share WW Broadband Subscriber Additions  (DellOro) 100% 80% PON 60% Ethernet/Other 40% VDSL ADSL/SHDSL 20% Cable modem 0% 2010 2011 2012 2013 2014 2015 COPYRIGHT © 2011 ALCATEL-LUCENT.

  • 4. BANDWIDTHIS NO LONGER THE CAPTAIN 2010 2015 2020 GPON has enough bandwidth for FTTH beyond 2020 GPON • Lower power dissipation • Symmetrical bandwidth • Resiliency at lower cost 10G PON • ONU evolution • Reduced opex TWDM PON-Drivers for 10G PON ready ONU•FTTB/DSLAM•FTTBusiness NGPON2 (40G PON)•More bandwidth at (Plan)same cost as GPON Drivers for NGPON2(not yet foreseeable) •More bandwidth for FTTB/DSLAM/Business •CO consolidation• Non-FTTH bandwidth drivers for 10G PON are low volume Market needs are: • Bandwidth-independent• Non-FTTH bandwidth drivers for NGPON2 are speculative • More customer-specific COPYRIGHT © 2011 ALCATEL-LUCENT.

Backwards-compatible, power-splitting Loss ~insensitive to split ratio. Bandwidth More on-demand bandwidth Symmetrical bandwidth Higher risk in 2015 Lower risk in 2015 Higher risk in 2015Implementation Higher speed components • In the short run, higher speed components cost more, but reduce over time More components and higher complexity • Over time, cost will be determined by the no. of components and complexity COPYRIGHT © 2011 ALCATEL-LUCENT.

  • 6. NGPON2 COST EVOLUTIONQUALITATIVE PICTURE If we needed NGPON2 today: •XLG-PON would be the most expensive: cost of 40G components and higher optical power •TWDM PON would the lowest cost: leverages existing XG-PON technology Cost cross-over between XLG- PON and TWDM-PON Cost per subscriber WDM PON TWDM‐PON XLG‐PON At some point in the future: Time •XLG-PON will be the least expensive: fewest components, lowest complexity Point for BW per Today lambda shift ? 6 COPYRIGHT © 2011 ALCATEL-LUCENT.
