    We propose a novel low-complexity artificial neural
    network (ANN)-based nonlinear equalizer (NLE) for coherent
    optical orthogonal frequency-division multiplexing (CO-OFDM)
    and compare it with the recent inverse Volterra-series transfer
    function (IVSTF)-based NLE over up to 1000 km of uncompensated
    links. Demonstration of ANN-NLE at 80-Gb/s CO-OFDM
    using 16-quadrature amplitude modulation reveals a Q-factor
    improvement after 1000-km transmission of 3 and 1 dB with
    respect to the linear equalization and IVSTF-NLE, respectively.
