The Gaussian Noise Model in the Presence of Inter-channel Stimulated Raman Scattering
Daniel Semrau, Polina Bayvel
A Gaussian noise (GN) model is presented that properly accounts for an arbitrary frequency dependent signal power profile along the link. This enables the evaluation of the impact…
Digital Nonlinearity Compensation in High-Capacity Optical Fibre Communication Systems: Performance and Optimisation
Tianhua Xu, Nikita A. Shevchenko, Boris Karanov +4
Meeting the ever-growing information rate demands has become of utmost importance for optical communication systems. However, it has proven to be a challenging task due to the pres…
Comparison of Low Complexity Coherent Receivers for UDWDM-PONs (-to-the-user)
M. Sezer Erkılınç, Domaniç Lavery, Kai Shi +4
It is predicted that demand in optical access networks will reach multi-Gb/s per user. However, the limited performance of the direct detection receiver technology currently used i…
A Simple Nonlinearity-Tailored Probabilistic Shaping Distribution for Square QAM
Eric Sillekens, Daniel Semrau, Gabriele Liga +6
A new probabilistic shaping distribution that outperforms Maxwell-Boltzmann is studied for the nonlinear fiber channel. Additional gains of 0.1 bit/symbol MI or 0.2 dB SNR for both…
The Impact of Transceiver Noise on Digital Nonlinearity Compensation
Daniel Semrau, Domanic Lavery, Lidia Galdino +2
The efficiency of digital nonlinearity compensation (NLC) is analyzed in the presence of noise arising from amplified spontaneous emission noise (ASE) as well as from a non-ideal t…
Achievable information rates estimates in optically-amplified transmission systems using nonlinearity compensation and probabilistic shaping
Daniel Semrau, Tianhua Xu, Nikita A. Shevchenko +4
Achievable information rates (AIRs) of wideband optical communication systems using ~40 nm (~5 THz) EDFA and ~100 nm (~12.5 THz) distributed Raman amplification are estimated based…
