On the Impact of Gas-Line Absorption in Long-Haul C+L-Band Hollow-Core Fibre Transmission
Zelin Gan, Eric Sillekens, Jiaqian Yang +5
We numerically investigate gas-line absorption in hollow-core fibre C+L-band transmission. Results show limited C-band but severe L-band performance degradation. Ideal suppression…
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…
Gas Line Absorption Mitigation in Hollow-Core Fibre using Spectral Pre-Equalisation
Eric Sillekens, Ronit Sohanpal
We study the impact of CO 2 absorption on hollow-core fibre transmission. Using spectral pre-equalisation, we digitally post-compensate gas-line absorption and show a 5.5 dB reduct…
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…
