One Terahertz Full-Field Digital Back-Propagation over 3000 km
Eric Sillekens, Ruben S. Luis, Giammarco Di Sciullo +14
We implement full-field digital back-propagation with a 1-THz receiver using 20 synchronous frequency-adjacent coherent receivers with digital stitching and a frequency-comb local…
On the Optimum Energy-per-bit Launch Power in Coherent Hollow-core Fibre Transmission Systems
Ronit Sohanpal, Eric Sillekens, Mindaugas Jarmolovicius +2
We investigate the optimum energy per bit in hollow-core-fibre transmission systems. We show that a 1000 km C-band link can achieve a 41.5% reduction in total power consumption whe…
423.7 + 426.5 Tb/s GMI Bi-Directional HCF Transmission
Jiaqian Yang, Romulo Aparecido, Eric Sillekens +28
We demonstrate OESCL-band same-wavelength bi-directional transmission over 60 km HCF with 42.5 THz bandwidth, achieving GMIs comparable with the highest unidirectional SMF data-rat…
Ultra-Wideband Transmission Systems From an Energy Perspective: Which Band is Next?
Ronit Sohanpal, Mindaugus Jarmolovicius, Jiaqian Yang +9
Measuring the power efficiency of the state-of-the-art OESCL-band amplifiers, we show that 1000 km OESCL-band systems can achieve 2.98x greater throughput for +48% higher energy-pe…
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…
