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…

A Closed-form Expression of the Gaussian Noise Model Supporting O-Band Transmission
Zelin Gan, Henrique Buglia, Romulo Aparecido +6
We present a novel closed-form model for nonlinear interference (NLI) estimation in low-dispersion O-band transmission systems. The formulation incorporates the four-wave mixing (F…

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…
