Impact of relaxed dispersion map and gain ripple on ultra-wideband 10 Gbit∕s transmission

Abstract
The performance of a wide, 53 nm-band fibre-optic transmission system that does not employ slope-matched dispersion-compensation modules or gain-equalisation filters is studied. Despite having a 2 dB maximum transmission penalty resulting from the non-ideal dispersion map, the Raman-based system exhibits a high system margin of at least 5 dB at 1600 km.
