Archivio Istituzionale della RicercaWe analyze the impact of finite resolution of DAC and ADC on the performance of coherent-detection optical communication systems using probabilistically-shaped 64-QAM constellations. We show that no substantial additional penalty is incurred with respect to uniformly distributed constellations with the same net data rate.

Abstract
We analyze the impact of finite resolution of DAC and ADC on the performance of coherent-detection optical communication systems using probabilistically-shaped 64-QAM constellations. We show that no substantial additional penalty is incurred with respect to uniformly distributed constellations with the same net data rate.
