Propagation impairments due to Raman effect on the coexistence of GPON, XG-PON, RF-video and TWDM-PON

摘要

We analyze propagation effects in the coexistence of GPON, XG-PON, RF-Video and TWDM-PON. We show that high power TWDM-PON channels excite Stimulated Raman Scattering inducing extra-loss on GPON due to power depletion. We address the problem through simulations and propose and validate a simple analytical model for the effect
