Fiber nonlinearity mitigation in 428-Gb/s multiband coherent optical OFDM systems

We propose DFT-spread (DFT-S) OFDM within each sub-band of multiband-CO-OFDM to mitigate fiber nonlinearity. For 1000-km standard-single-mode-fiber transmission at 420-Gb/s, 32-band DFT-S CO-OFDM outperforms conventional CO-OFDM and coherent single-carrier by 1.1 and 0.8 dB, respectively.
