Field Demonstration of 1 Tbit/s Super-Channel Network Using Probabilistically Shaped Constellations

We successfully tested the suitability of probabilistically shaped constellations in field environment. We performed 1 Tbit/s 4-carriers super-channel transmission in the German nationwide backbone network with an extended family of probabilistically shaped constellations using 16QAM, 36QAM and 64QAM.
