  1. 1. Research directions forenergy efficient wireline access April 04, 2012 Peter.Vetter@alcatel-lucent.com Peter Vetter, Dusan Suvakovic, Keith Chow
  2. 2. Wireline Access WG Target: 10x per user – 100x efficiency gain Un-cooled tunable lasers Novel PON protocols; Virtual Low power CPE PON Sleepmode HGWMin. energy access architectures Fiber in the Home Also: Hybrid PON TNO ZTE, KAIST Low power OFDM in optical access
  3. 3. Wireline Access: GPON, XGPON and BI-PON 10.0 GPON XGPON 8.0 Sleepmode EE HW design Wireless LAN 6.0W/subscriber OLT(/subscriber) Sleepmode 2 HGW processor Virtual HGW Wireline LAN (Eth.)

  4. 4. Fast Sleep Mode Aim for awake time ONU proportional to useful payload Challenges  Schedule probing cycles and awake time with minimum impact on QoE  Minimize power during sleep state  Minimize wake-up time P Active state: Probing Bursts of data Fast sleep state: No data e.g. ~10 ms t

  11. 11. Virtual Home Gateway / Quasi-passive CPE Transparent CPE providing connectivity in-house and to network • Functions of current CPE moved to virtual HGW in network • Low power connectivity (“quasi-passive”) or transparant (“passive”) CPE Savings: • Cut-through of high bitrate services to terminal: LAN interfaces on CPE • Lower power by processor platform sharing Virtual HGW performs - routing and NAT Quasi-passive CPE - firewalling - OAM management
