Abstract

Non-linear tolerance measurements of DP-16QAM (28 Gbd) signals with transmitter based digital signal pre-distortion are reported, showing systematic performance gains of fibre launch power versus pre-distortion (~1.5 dB for 6 uncompensated SMF spans) and a distinct reduction of the non-linear threshold spans scaling factor.
