First Experimental Demonstration of Probabilistic Enumerative Sphere Shaping in Optical Fiber Communications

Abstract

We transmit probabilistic enumerative sphere shaped dual-polarization 64-QAM at 350Gbit/s/channel over 1610km SSMF using a short blocklength of 200. A reach increase of 15% over constant composition distribution matching with identical blocklength is demonstrated.
