Abstract

In this paper we propose to evaluate the possibility of applying the method known as differential transformation of signals to reduce the dynamic range of optical signals for mitigation of impairments caused by Kerr-nonlinearities. The essence of this method is as follows. The channel signal is the difference between the original signal and its extrapolated values. We have simulated nonlinear propagation of proposed signal and original signal to define nonlinear impairments reduction due to signal compression. Presented results show that differential transformation of signal allows to sufficiently mitigate envelope distortions caused by self-phase modulation and cross-phase modulation.
