Regular Perturbation on the Group-Velocity Dispersion Parameter for Dual-Polarization Short-Reach Systems
Dario Cellini, Vinícius Oliari, Erik Agrell +3
The Manakov equation governs the propagation of signals in dual-polarization systems. Its solution is usually approximated by regular perturbation on the nonlinear Kerr parameter.…
The Memory-Enhanced Gaussian Noise (MEGN) Model for Fiber-Optic Channels
Kaiquan Wu, Gabriele Liga, Marco Secondini +5
The enhanced Gaussian noise (EGN) model is widely used for estimating the nonlinear interference (NLI) power accumulated in coherent fiber-optic transmission systems. Given a fixed…
Joint Subcarrier Phase Recovery for Nonlinearity Mitigation
Marco Secondini, Stella Civelli
We propose a low-complexity phase recovery scheme that simultaneously mitigates laser phase noise and fiber nonlinearity across several subcarriers. In a long single-span link with…
ML-Enhanced Digital Backpropagation for Long-Reach Single-Span Systems
Dario Cellini, Stella Civelli, Marco Secondini
We propose a digital backpropagation method that employs machine-learning-aided joint optimization of dispersion step lengths and nonlinear phase rotation filters within an FFT-bas…
