Introducing Combined Effects of Filtering and ASE Noise in Optical Links Supposing Different Equalization Algorithms
Enrico Miotto, Andrea Rosso, Emanuele Virgillito +5
This paper develops and validates a discrete-time modeling framework for the joint impact of cascaded optical filtering, distributed ASE noise, and transceiver noise in coherent op…
Accumulation of cross-channel non-linear interference in dispersion-managed and disaggregated optical network segment
Elliot London, Emanuele Virgillito, Andrea D'Amico +1
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 fra…
Analysis of the Coherent Contributions to Nonlinear Interference Generation within Disaggregated Optical Line Systems
Elliot London, Emanuele Virgillito, Andrea D'Amico +2
Through a physical layer simulation study we highlight that the coherent accumulation of nonlinear interference becomes non-negligible for optical networks operating within high sy…
Observing the Effect of Polarization Mode Dispersion on Nonlinear Interference Generation in Wide-Band Optical Links
Dario Pilori, Mattia Cantono, Alessio Ferrari +2
With the extension of the spectral exploitation of optical fibers beyond the C-band, accurate modeling and simulation of nonlinear interference (NLI) generation is of the utmost pe…
An ultra-fast method for gain and noise prediction of Raman amplifiers
Ann Margareth Rosa Brusin, Vittorio Curri, Darko Zibar +1
A machine learning method for prediction of Raman gain and noise spectra is presented: it guarantees high-accuracy (RMSE < 0.4 dB) and low computational complexity making it suitab…
Observing the Effects of Legacy 10G on 100G Channels in Dispersion Managed Optical Systems
Emanuele Virgillito, Andrea Castoldi, Stefano Straullu +3
We show that 10G channels generate both amplitude and phase noise on 100G channels. Amplitude noise can be managed as the ASE and NLI noise, while the DSP robustness to the phase n…
