Abstract :
The effect of Stimulated Raman Scattering (SRS) crosstalk in Passive Optical Network (PON) has been reported in several papers. We present a possible solution of this problem in PON systems carrying sub-carrier multiplexed video signals. This is done by the use of quadrature amplitude modulation (QAM) for modulating the video signals instead of implementing the widely used analog RF-overlay method.
