Abstract
Raman interference (also known as Raman scattering) during an idle frame transmission state in a passive optical network (PON) having radio frequency video overlay is reduced by generating and transmitting data packets having both random data and random length. Randomly varying both the packet data content and the packet length can achieve significant improvement in Raman interference reduction. The random packet data and length in effect spreads the interference across a spectrum wide enough that there is no interference effect perceptible to a television viewer.
