我们提出了一种新颖且统一的算法，可以根据相干光接收器中自适应有限脉冲响应（FIR）滤波器的抽头系数来估计光传输系统中的线性损伤。可测量的损伤包括色散 (CD)、两个主要偏振状态之间的差分群延迟 (DGD)、二阶偏振模色散 (二阶 PMD) 和偏振相关损耗 (PDL)。我们通过双偏振正交相移键控 (QPSK) 传输实验验证了我们的多损伤监测算法。
We propose a novel and unified algorithm that estimates linear impairments in optical transmission systems from tap coefficients of an adaptive finite-impulse response (FIR) filter in a coherent optical receiver. Measurable impairments include chromatic dispersion (CD), differential group delay (DGD) between two principal states of polarization, second-order polarization-mode dispersion (second-order PMD), and polarization-dependent loss (PDL). We validate our multi-impairment monitoring algorithm by dual-polarization quadrature phase-shift keying (QPSK) transmission experiments.
