30% Reach Increase via Low-complexity Hybrid HD/SD FEC and Nonlinearity-tolerant 4D Modulation
Gabriele Liga, Bin Chen, Sjoerd van der Heide +4
Current optical coherent transponders technology is driving data rates towards 1 Tb/s/λand beyond. This trend requires both high-performance coded modulation schemes and efficient…
Deep Learning for Communication over Dispersive Nonlinear Channels: Performance and Comparison with Classical Digital Signal Processing
Boris Karanov, Gabriele Liga, Vahid Aref +3
In this paper, we apply deep learning for communication over dispersive channels with power detection, as encountered in low-cost optical intensity modulation/direct detection (IM/…
An Improved Model of Nonlinear Fiber Propagation in the Presence of Kerr Nonlinearity and Stimulated Raman Scattering
Hami Rabbani, Gabriele Liga, Vinicius Oliari +4
Ultra-wideband fiber optical transmission suffers from both Kerr nonlinearity and stimulated Raman scattering (SRS). Mathematical models that address the interplay between Kerr non…
Improving HD-FEC decoding via bit marking
Alex Alvarado, Gabriele Liga, Yi Lei +2
We review the recently introduced soft-aided bit-marking (SABM) algorithm and its suitability for product codes. Some aspects of the implementation of the SABM algorithm are discus…
A novel soft-aided bit-marking decoder for product codes
Gabriele Liga, Alireza Sheikh, Alex Alvarado
We introduce a novel soft-aided hard-decision decoder for product codes adopting bit marking via updated reliabilities at each decoding iteration. Gains up to 0.8 dB vs. standard i…
11,700 km Transmission at 4.8 bit/4D-sym via Four-dimensional Geometrically-shaped Polarization-Ring-Switching Modulation
Sjoerd van der Heide, Bin Chen, Menno van den Hout +5
Using a novel geometrically-shaped four-dimensional modulation format, we transmitted 11x200 Gbit/s DWDM at 4.8 bit/4D-sym over 7,925 km and 11,700 km using EDFA-only and hybrid am…
Revisiting Multi-Step Nonlinearity Compensation with Machine Learning
Christian Häger, Henry D. Pfister, Rick M. Bütler +2
For the efficient compensation of fiber nonlinearity, one of the guiding principles appears to be: fewer steps are better and more efficient. We challenge this assumption and show…
Improved Decoding of Staircase Codes: The Soft-aided Bit-marking (SABM) Algorithm
Yi Lei, Bin Chen, Gabriele Liga +5
Staircase codes (SCCs) are typically decoded using iterative bounded-distance decoding (BDD) and hard decisions. In this paper, a novel decoding algorithm is proposed, which partia…
