Sensitivity Gains by Mismatched Probabilistic Shaping for Optical Communication Systems
Tobias Fehenberger, Domaniç Lavery, Robert Maher +3
Probabilistic shaping of quadrature amplitude modulation (QAM) is used to enhance the sensitivity of an optical communication system. Sensitivity gains of 0.43 dB and 0.8 dB are de…
A Lower Bound on the per Soliton Capacity of the Nonlinear Optical Fibre Channel
Nikita A. Shevchenko, Jaroslaw E. Prilepsky, Stanislav A. Derevyanko +3
A closed-form expression for a lower bound on the per soliton capacity of the nonlinear optical fibre channel in the presence of (optical) amplifier spontaneous emission (ASE) nois…
On the Impact of Optimal Modulation and FEC Overhead on Future Optical Networks
Alex Alvarado, David J. Ives, Seb Savory +1
The potential of optimum selection of modulation and forward error correction (FEC) overhead (OH) in future transparent nonlinear optical mesh networks is studied from an informati…
Replacing the Soft FEC Limit Paradigm in the Design of Optical Communication Systems
Alex Alvarado, Erik Agrell, Domanic Lavery +2
The FEC limit paradigm is the prevalent practice for designing optical communication systems to attain a certain bit-error rate (BER) without forward error correction (FEC). This p…
On Achievable Rates for Long-Haul Fiber-Optic Communications
Tobias Fehenberger, Alex Alvarado, Polina Bayvel +1
Lower bounds on mutual information (MI) of long-haul optical fiber systems for hard-decision and soft-decision decoding are studied. Ready-to-use expressions to calculate the MI ar…
