Joint probabilistic and geometric shaping is considered for flexible PON. Optimal modulation is found through ANN, which generalizes to various ROPs and fiber lengths while taking dispersion, limited bandwidth, and receiver-side DSP into account.

The pairwise probabilistic combined with geometric shaping is applied to IMDD system. With shaped PAM signals, the flexible information rate beyond 100Gb/s is experimentally demonstrated for the first time in a practical PON link.

The use of coherent techniques for TDM-PON including its link budget and complexity is discussed. NRZ modulation with EML in two polarizations combined with coherent detection is experimentally exemplified as a candidate for cost-effective solution.

DFE induced error correlation and mutual information (MI) degradation penalize the 50G PON LDPC code soft-input decoding performance. Bit-interleaving across multiple codewords mitigates the correlated error penalty, but not the MI degradation penalt

DSP techniques are presented for hybrid modulated TDM-PON. FFE/DFE and various CDRs are tested with measured 50G/100G NRZ/PAM4 hybrid modulated data with 25G commercial devices. The measured data are further processed offline for the worst-case ISI t

Performance of Deep Neural Network receiver equalization is investigated after LDPC FEC. It is shown that DNN equalization results in a lower level of error clustering and higher performing equalization relative to more traditional equalization for b
