Information Rate in Ultra-Wideband Optical Fiber Communication Systems Accounting for High-Order Dispersion
Nikita A. Shevchenko, Tianhua Xu, Cenqin Jin +3
The effect of Kerr-induced optical fiber nonlinearities in C-band (5 THz) EDFA and C+L-band (12.5 THz) Raman-amplified optical communication systems has been studied considering th…
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…
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…
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…
