  • Standardization of the Next Generation Access(NG-PON2) expected by ~2015 FSAN NG-PON technology roadmap Operator founded group workingtowards common PONstandards for the ITU-T ITU-T SG15 Q2Standard Body (GPON) FSAN currently expects FSAN current activity: NG-PON2 standardization • Technology assessment by ~2015. • NGA requirements Whitepaper 8 © 2011 Nokia Siemens Networks Research FTTH Council Europe 08.02.2011 Milan
  • BPON, GPON, NG-PON1, NG-PON2, XG-PON1 Definition of NG-PON1: Supports the coexistence with GPON on the same ODN. The coexistence feature enables seamless upgrade of individual customers to NG-PON on a live ODN without disrupting services of other customers. Defined by recommendation G.984.5 Definition of NG–PON2: "Disruptive" NG-PON with no requirement in terms of coexistence with G-PON on the same ODN. 9 © 2011 Nokia Siemens Networks Research FTTH Council Europe 08.02.2011 Milan

  • G.984.5 Enhancement bandCoexistence of GPON and NG-PON1• Recommendation defines wavelength ranges reserved for additional service signals to be overlaid via wavelength division multiplexing (WDM) in future gigabit capable passive optical networks (G-PON) for maximizing the value of optical distribution networks (ODNs)• Other PON systems, such as B-PON, have wavelength plans based on [ITU-T G.983.3], which includes existing options for enhancement bands• This Recommendation also defines further wavelength ranges reserved for additional service signals to be overlaid via WDM in future PONs whose wavelength allocations are based on [ITU-T G.983.3] Source of picture: ITU-T WBF Wavelength blocking filter WDM-N WDM filter GPON ONU to combine/isolate WDM-NGA WDM filter for NGA ONU & Video WDM-L WDM filter for NGA OLT WDM 1(r) WDM filter at CO to combine/isolate GPON/NGA & video 15 © 2011 Nokia Siemens Networks Research FTTH Council Europe 08.02.2011 Milan
  • Unbundling options Unbundling Options P2P G-PON WDM-PON Coherent PON XG-PON Duct sharing Valid option, however economically challenging & regulation may apply Spectrum sharing without segregation filters Layer 1 unbundling type: Best option for unbundling at OLT level Spectrum sharing with segregation filters Layer 1 unbundling type: Expensive and inflexible but good power budget Bitstream unbundling in OLT Layer 2 unbundling type: It gives competitors no direct access to the PON PPP/L2TP based Bitstream unbundling in IP Edge Layer 2 unbundling type: Solution of today, works typically at best effort 16 © 2011 Nokia Siemens Networks Research FTTH Council Europe 08.02.2011 Milan
