We propose a fast quality of transmission (QoT) estimation method based on cascaded artificial neural networks (ANNs) for intensity modulation-direct detection (IMDD) systems. The proposed method can calculate the bit error rate of three-span 36 km transmission within 0.7 seconds while taking account of the deterministic waveform distortion caused by the chromatic dispersion and self-phase modulation (SPM).
我们提出了一种基于级联人工神经网络(ANN)的快速传输质量(QoT)估计方法,用于强度调制直接检测(IMDD)系统。该方法能够在考虑由色散和自相位调制(SPM)引起的确定性波形失真的情况下,在0.7秒内计算出三跨36公里传输的误码率。
