Tb/s Transmission in Sustainable and Flexible Metro Networks using Long-Wavelength VCSELs

Tb/s transmission for future metropolitan networks is demonstrated thanks to an innovative photonic cost-effective and energy-efficient transmitter module integrating multiple directly modulated long-wavelength InP VCSELs targeting more than 50-Gb/s per channel, together with multi-core fiber propagation. © Optica Publishing Group 2021This paper has been supported by the H2020 PASSION Project (GA 780326) and by the MIUR PRIN2017 FIRST Project (GA 2017HP5KH7_002).
