Abstract :
The nonlinear distortion caused by the interaction between chromatic dispersion and direct detection reduces the capacity of optical discrete multi-tone system beyond dozens of kilometers. The proposed nonlinear equalizer compensated the distortion and increased the capacity by up to 50%.
