Keywords:nonlinear fiber optics, digital back propagation

We have theoretically evaluated transmission property and bit error rate (BER) performance of 120Gbps DP-16QAM digital coherent signals, with and without nonlinear compensation by means of the digital back propagation. In case of single channel transmission, the maximum input power set by the fiber nonlinearity could be increased as large as 2.0 dB by using the nonlinear compensation. The improvement has been reduced to 0.6dB in DWDM transmission systems due to disturbance from neighboring DWDM channels.
