RF video overlay in an Ethernet passive optical network

This paper studies the effects of non-linear Raman cross-talk in an RF video overlay in an Ethernet based passive optical network. We show that the Raman cross-talk between the 1490 nm and the 1550 nm wavelengths and the presence of idle frames seriously limits analog video transmission at some specific frequencies. Digital video transmission based on quadrature amplitude modulation is possible, however.
