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 NGPON2: "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 Europe08.02.2011 Milan 10.
