摘要：

We report a numerical simulation of the propagation of short (25 ps) 8QAM pulses for two polarisations in a nine-channel communication line with a frequency band of 80 GHz. It is shown that the use of large-chirp pulses and different dispersion compensators leads to effective suppression of nonlinear distortions and significantly improves the signal quality in a multichannel communication line due to the rapid pulse broadening.
