Bit Pattern Length Dependence of Intra-channel Nonlinearities in Pseudo-linear Transmission

A dependence of nonlinear transmission penalty om bit sequence length in pseudo-linear transmission is demonstrated and studied. It is shown that, for a realistic dispersion map, bit sequence lengths incorporating tens of thousands of bits or more may become necessary to accurately capture the nonlinear transmission penalty due to intra-channel nonlinear efforts, especially at low bit error ratio (
