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.

具有可变二次色散补偿的高速多信道通信线路中的非线性失真抑制

我们报告了在频带为 80 GHz 的九通道通信线路中两个极化的短 (25 ps) 8QAM 脉冲传播的数值模拟。结果表明，使用大啁啾脉冲和不同的色散补偿器可以有效抑制非线性失真，并由于脉冲的快速展宽而显着改善多通道通信线路中的信号质量。
