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…

Measurement and Analysis of the Power Consumption of Hybrid-Amplified SCL-band Links

Ronit Sohanpal, Jiaqian Yang, Eric Sillekens +5

We studied the power consumption of hybrid-amplified SCL-band links using commercial benchtop amplifiers and Raman pumps. We show a reduction in energy per bit for multi-span hybri…

On the Feasibility of SCL-Band Transmission over G.654.E-Compliant Long-Haul Fibre Links

Jiaqian Yang, Eric Sillekens, Ronit Sohanpal +10

We demonstrate the first SCL-band long-haul transmission using G.654.E-compliant fibre, achieving 100.8 Tb/s (GMI) over 1552 km, despite its 1520 nm cutoff wavelength. Due to the 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…
