Performance study of a coexistence system in a PON network taking into account the stimulated scattering of Raman [PDF]
Some problems introduced by the need for coexistence between a Passive Optical Network PON technologies (GPON, XGS-PON, and NG-PON2 in particular) especially the Stimulated Raman Scattering SRS which appears when different PON technologies transfer ...
