Recently when we cleared some litter from the mountains I mentioned that we are like little wall-E, cleaning up.
And today my wife presented this one little addon to our home 😍 Maybe I'll bring him to the mountains to help cleaning up.
And if not, I'm just thankful to my wife for it.

A Closed-form Expression of the Gaussian Noise Model Supporting O-Band Transmission
We present a novel closed-form model for nonlinear interference (NLI) estimation in low-dispersion O-band transmission systems. The formulation incorporates the four-wave mixing (FWM) efficiency term as well as the coherent contributions of self- and cross-phase modulation (SPM/XPM) across multiple identical spans. This extension enables accurate evaluation of the NLI in scenarios where conventional closed-form Gaussian Noise (GN) models are limited. The proposed model is validated against spli…
