A novel transmission system that adaptively compensates for intra‐ and inter‐channel nonlinear distortions while alleviating the computation load is described. It does so by using an optical dispersion compensation at optical nodes and a Volterra‐based multi‐channel nonlinear equalisation. Simulation results show that 3.8 dB Q ‐factor improvements are obtained against conventional systems that do not compensate for nonlinear distortions.
