Standardization of the Next Generation Access (NG-PON2) expected by ~2015 Operator founded group working towards common PON standards for the ITU-T FSAN NG-PON technology roadmap

11 Standardization of the Next Generation Access (NG-PON2) expected by ~2015 Operator founded group working towards common PON standards for the ITU-T FSAN NG-PON technology roadmap ITU-T SG15 Standard Body (GPON) FSAN currently expects NG-PON2 standardization by ~2015. Coherent PON actually in discussion as technology option for NG-PON2 11 Nokia Siemens Networks

12 Future proof optical distribution network (ODN): network without any filters Enable flexible sharing of wavelength spectrum in order to allow coexistence of services & technologies today and in the future Avoid separation of the ODN with filters by consequent use of splitters G.984.splitter Single Fiber ITU G.652 GPON O-Band E-Band S-Band C-B.

13 How to ensure security, protection and privacy on shared access media like PONs GPON security today is ensured by means of secure authentication and payload encryption. Coherent PON adapts similar, proven mechanisms (but bi-directional) and leverages on unshared wavelengths which are centrally and securely managed. Methods of handling rogue wavelengths are under investigation. 13 Nokia Siemens Networks
