Abstract
The performance of a wideband coherent receiver was investigated. The relative impact of digital pre-distortion, geometric constellation shaping and pilot sequence detection, as well as the number of sub-channels in the super-channel, on the receiver performance was explored. The detection of a net data rate of 2.36 Tb/s after 75 km transmission of a 8 × 26 GBd DP-GS-256-QAM super-channel was demonstrated using a single 110 GHz electrical bandwidth receiver. The overall improvement due to the digital pre-distortion and tailored geometric constellation shaping was 1.2 bit/4D-sym in the achievable information rate..
