An Analytical Model for Performance Estimation in High-Capacity IMDD Systems
Giuseppe Rizzelli, Pablo Torres-Ferrera, Fabrizio Forghieri +1
In this paper, we propose an analytical model to estimate the signal-to-noise ratio (SNR) at the output of an adaptive equalizer in intensity modulation and direct detection (IMDD)…
Scaling Laws for Unamplified Coherent Transmission in Next-generation Short-Reach and Access Networks
Giuseppe Rizzelli, Antonino Nespola, Stefano Straullu +1
International standardization bodies (IEEE and ITU-T) working on the evolution of transmission technologies are still considering traditional direct detection solutions for the mos…
Accurate Closed-Form Real-Time EGN Model Formula Leveraging Machine-Learning over 8500 Thoroughly Randomized Full C-Band Systems
Mahdi Ranjbar Zefreh, Fabrizio Forghieri, Stefano Piciaccia +1
We derived an approximate non-linear interference (NLI) closed-form model (CFM), capable of handling a very broad range of optical WDM system scenarios. We tested the CFM over 8500…
A GN/EGN-Model Real-Time Closed-Form Formula Tested over 7,000 Virtual Links
Mahdi Ranjbar Zefreh, Andrea Carena, Fabrizio Forghieri +2
We derived a fully-closed-form GN-model formula and tested its accuracy of over 7,000 highly randomized Cband system scenarios. By further applying a correction that leverages the…
A Simple and Accurate Closed-Form EGN Model Formula
P. Poggiolini, Y. Jiang, A. Carena +1
The GN model of non-linear fiber propagation has been shown to overestimate the variance of non-linearity due to the signal Gaussianity approximation, leading to maximum reach pred…
Electronic Dispersion Pre-Compensation in PM-QPSK Systems over Mixed-Fiber Links
A. Carena, Y. Jiang, P. Poggiolini +3
Dispersion pre-compensation is shown to potentially lead to a substantial non-linearity reduction in PM-QPSK links that use a mixture of high and low dispersion fibers. However, th…
On the Impact of Non-Linear Phase-Noise on the Assessment of Long-Haul Uncompensated Coherent Systems Performance
Y. Jiang, A. Carena, P. Poggiolini +1
We accurately characterize nonlinear phase noise in uncompensated coherent optical systems. We find that, though present, its impact on system performance is typically negligible i…
Impact of Low-OSNR Operation on the Performance of Advanced Coherent Optical Transmission Systems
P. Poggiolini, A. Carena, Y. Jiang +3
We find evidence that low-OSNR operation causes substantial penalty on system maximum reach due to non-linearity generated by ASE noise and due to signal-power conversion into non-…
A Simple and Effective Closed-Form GN-Model Correction Formula Accounting for Signal Non-Gaussian Distribution
P. Poggiolini, G. Bosco, A. Carena +3
The GN model of non-linear fiber propagation has been shown to overestimate the variance of non-linearity due to the signal Gaussianity approximation, leading to maximum reach pred…
A Detailed Analytical Derivation of the GN Model of Non-Linear Interference in Coherent Optical Transmission Systems
Pierluigi Poggiolini, Gabriella Bosco, Andrea Carena +3
Recently, a perturbative model of non-linear fiber propagation in uncompensated optical transmission systems has been proposed, called GN-model [1]. Here, an extended and more deta…
