Abstract :
We investigate experimentally and analytically effects due to stimulated Raman scattering on a 1550 nm sub-carrier multiplexed video signal when co-propagating with 1490 nm digital traffic in a passive optical network. If certain design rules are not followed, up to 5 dB of CNR degradation at the lowest frequency video channel is possible.
