Abstract
Employing probabilistic constellation shaping with jointly optimized entropy and symbol-rate, we demonstrate that the tolerance towards WSS filtering can be significantly enhanced. Compared with standard uniform modulation, OSNR gains in the range of 1–3 dB are experimentally demonstrated for 400G–600G systems, after 5–10 WSS passes.
