Performance of Probabilistic Shaping Coherent Channels in Hybrid Systems. Villafani, D., Mirani, A., Åhlfeldt, H., Schröder, J., Karlsson, M., & Andrekson, P. In 2020 22nd International Conference on Transparent Optical Networks (ICTON), pages 1–3, July, 2020. ISSN: 2161-2064

We present the performance comparison of probabilistically shaped 64QAM with uniform 16/32QAM in hybrid systems. The results show that the PS signal can increase the maximum reach and is more tolerant to strong nonlinear interference. Nevertheless, when the nonlinear interference is weak, uniform formats can provide higher performance.
