Mitigating Fiber Nonlinearities by Short-length Probabilistic Shaping
Tobias Fehenberger, Helmut Grießer, Jörg-Peter Elbers
Abstract
We show that short-length probabilistic shaping reduces nonlinear interference in optical fiber transmission. SNR improvements of up to 0.8 dB are obtained. The shaping gain vanishes when interleaving is employed and not undone before transmission.
