Propagation impairments due to Raman effect on the coexistence of GPON, XG-PON, RF-video and TWDM-PON [PDF]
, 2013 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.

A Viable Passive Optical Network Design for Ultrahigh Definition TV Distribution
Advances in OptoElectronics, Volume 2013, Issue 1, 2013., 2013 International Telecommunication Union (ITU) has recently standardized ultrahigh definition television (UHD‐TV) with a resolution 16 times more than the current high definition TV. An increase in the efficiency of video source coding or in the capacity of transmission channels will be needed to deliver such programs by passive optical network (PON).
