Enumerative Sphere Shaping for Rate Adaptation and Reach Increase in WDM Transmission Systems

Abstract

The performance of enumerative sphere shaping (ESS), constant composition distribution matching (CCDM), and uniform signalling are compared at the same forward error correction rate. ESS is shown to offer a reach increase of approximately 10% and 22% compared to CCDM and uniform signalling, respectively.
