Mitigating Fiber Nonlinearities by Short-length Probabilistic Shaping

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.
