Optimising O-to-U Band Transmission Using Fast ISRS Gaussian Noise Numerical Integral Model
Mindaugas Jarmolovičius, Daniel Semrau, Henrique Buglia +5
We model the transmission of ultrawideband signals, including wavelength-dependent fibre parameters: dispersion, nonlinear coefficient and effective fibre core area. To that end, t…
On the Relationship Between Network Topology and Throughput in Mesh Optical Networks
Daniel Semrau, Shahzaib Durrani, Georgios Zervas +2
The relationship between topology and network throughput of arbitrarily-connected mesh networks is studied. Taking into account nonlinear channel properties, it is shown that throu…
Modelling the delayed nonlinear fiber response in coherent optical communications
Daniel Semrau, Eric Sillekens, Robert I. Killey +1
Fiber nonlinearities, that lead to nonlinear signal interference (NLI), are typically regarded as an instantaneous material response with respect to the optical field. However, in…
The Benefits of Using the S-Band in Optical Fiber Communications and How to Get There
Daniel Semrau, Eric Sillekens, Robert I. Killey +1
The throughput gains of extending the optical transmission bandwidth to the S+C+L-band are quantified using a Gaussian Noise model that accounts for inter-channel stimulated Raman…
Modulation Format Dependent, Closed-Form Formula for Estimating Nonlinear Interference in S+C+L Band Systems
Daniel Semrau, Lidia Galdino, Eric Sillekens +3
A closed-form formula for the nonlinear interference estimation of arbitrary modulation formats in ultra-wideband transmission systems is presented. Enabled by the proposed approac…
Experimental Demonstration of Learned Time-Domain Digital Back-Propagation
Eric Sillekens, Wenting Yi, Daniel Semrau +9
We present the first experimental demonstration of learned time-domain digital back-propagation (DBP), in 64-GBd dual-polarization 64-QAM signal transmission over 1014 km. Performa…
