摘要：
我们使用分步傅里叶方法（SSFM）仿真和高斯噪声（GN）模型的实现，评估了在解聚光网络框架下，通过各种色散管理段进行相干传输时跨信道干扰（XCI）的生成。我们观察到每个跨段后残留的少量在线残余色散会影响XCI的积累，导致GN模型的预测不再保守。我们找到了这种额外积累的渐近上界，提供了最坏情况下的预测，并观察到这取决于链路内的残余色散。该上界与标度与自信道干扰（SCI）的积累相似，并且可以通过底层光纤跨段和传输信号的参数来很好地表征。
英文摘要：
We evaluate the generation of the cross-channel interference (XCI) for coherent transmission through a variety of dispersion-managed segments in a disaggregated optical network framework, using split-step Fourier method (SSFM) simulations and an implementation of the Gaussian noise (GN) model. We observe that the small inline residual dispersion remaining after each span affects the accumulation of the XCI, causing GN model predictions to no longer be conservative. We find an asymptotic upper bound to this additional accumulation, providing a worst-case prediction, and observe that this depends upon the residual dispersion within the link. This upper bound scales similarly to the self-channel interference (SCI) accumulation, and is well characterized by the parameters of the underlying fiber spans and the transmitted signals.
