End-to-End Modelling of Earthquake-Induced Polarisation Perturbations in Submarine Optical Fibres
Rick M. Butler, José Núñez-Kasaneva, Gabriele Liga +3
We present an end-to-end model of earthquake-perturbed signal propagation in submarine fibres. Ground displacements are converted to fibre strain via ocean pressure, and injected i…
Symbol Rate-Code Rate Trade-offs for IM/DD 200G/400G per Lane LPO Transceivers
José Núñez-Kasaneva, Yunus Can Gültekin, Stefanos Dris +3
We analyze the symbol rate-code rate trade-off in bandwidth-limited IM/DD systems targeting LPO transceivers, using PAM-4/6/8 as candidate modulation formats. We use the capacity o…
Regular Perturbation on the Group-Velocity Dispersion Parameter for Dual-Polarization Short-Reach Systems
Dario Cellini, VinÃcius 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…
On LLR Mismatch in Belief Propagation Decoding of Overcomplete QLDPC Codes
Hernan Cordova, Alexios Balatsoukas-Stimming, Gabriele Liga +2
Belief propagation (BP) decoding of quantum low density parity check (QLDPC) codes is often implemented using overcomplete stabilizer (OS) representations, where redundant parity c…
A General Nonlinear Model for Arbitrary Modulation Formats in the Presence of Inter-Channel Simulated Raman Scattering
Zhiwei Liang, Bin Chen, Jiwei Xu +4
The four-dimensional nonlinear model is extended to include the inter-channel stimulated Raman scattering, enabling accurate prediction of dual-polarization four-dimensional modula…
