The Coherent Polynomials Closed-Form Model for Evaluating Nonlinear Interference in Any Island

Yifeng Gao, Yanchao Jiang, Pierluigi Poggiolini

We improve the accuracy of the GN Polynomial Closed-Form Model (PCFM) by incorporating the spectral NLI PSD and the coherent accumulation along the link. The proposed model is capa…
