Low-Complexity Nonlinearity Compensation for Short-Reach IM/DD Systems Using PAM (Th1A.27)

Presenter: Tom Wettlin, Kiel University

We investigate the performance of non-regular PAM8 constellations and introduce a novel non-uniformly quantized equalizer to improve nonlinearity compensation in 70 GBd PAM8 back-to-back and 1 km SSMF transmission without additional complexity.
