Single-Step Digital Backpropagation for O-band Coherent Transmission Systems
Romulo Aparecido, Jiaqian Yang, Ronit Sohanpal +11
We demonstrate digital backpropagation-based compensation of fibre nonlinearities in the near-zero dispersion regime of the O-band. Single-step DBP effectively mitigates self-phase…
Experimental Demonstration of MPI-Penalty-Free S-band Transmission over G.654.E Fibres
Romulo Aparecido, Jiaqian Yang, John D. Downie +6
We demonstrate multipath interference-penalty-free S-band transmission over two G.654.E-compliant fibres with cable cutoff up to 1530 nm. No SNR degradation was observed across var…
Impact of launch power optimisation in hybrid-amplified links
Henrique Buglia, Eric Sillekens, Lidia Galdino +2
Per-channel launch power optimisation in a hybrid-amplified link with optimised pump powers and wavelengths is described. Compared to using the optimum spectrally uniform launch po…
A Modulation-Format Dependent Closed-form Expression for the Gaussian Noise Model in the Presence of Raman Amplification
H. Buglia, M. Jarmolovicius, L. Galdino +2
A closed-form expression that estimates the nonlinear interference of arbitrary modulation formats in Raman amplified links is presented. Accounting for any pumping schemes and int…
Throughput Maximisation in Ultra-wideband Hybrid-amplified Links
Henrique Buglia, Eric Sillekens, Lidia Galdino +2
A semi-analytical, real-time nonlinear-interference model including ASE noise in hybrid-amplified links is introduced. Combined with particle-swarm optimisation, the capacity of a…
A Closed-form Expression for the Gaussian Noise Model in the Presence of Raman Amplification
H. Buglia, M. Jarmolovicius, L. Galdino +2
A closed-form model for the nonlinear interference (NLI) in Raman amplified links is presented, the formula accounts for both forward (FW) and backward (BW) pumping schemes and int…
A Closed-form Expression for the ISRS GN Model Supporting Distributed Raman Amplification
H. Buglia, M. Jarmolovicius, A. Vasylchenkova +4
A closed-form model for the nonlinear interference in distributed Raman amplified links is presented, the formula accounts for both forward and backward pumping.
Experimental Analysis on Variations and Accuracy of Crosstalk in Trench-Assisted Multi-core Fibers
