Abstract

Nonlinear Fourier transform (NFT)-based nonlinear frequency division multiplexing (NFDM) system has the potential to overcome the limit of fiber nonlinearity. We have meticulously designed a b-modulated dual-polarization (DP) full-spectrum NFDM system with 128 subcarriers for continuous spectrum and 7 eigenvalues for discrete spectrum. By using probabilistic shaping (PS) and linear minimum mean square error (LMMSE), NFDM system transmits 960km distance with bit error rate (BER) lower 3.8 × 10⁻³, and the data rate achieves approximately 203.7Gb/s.
