Record-breaking optical fiber transmits 22.9 petabits per second, a significant increase achieved which is more than double the previous record of 10.66 Pb/s.
Researchers from the National Institute of Information and Communications Technology (NICT) achieved a groundbreaking feat by demonstrating a record-breaking data rate of 22.9 petabits per second using a single optical fiber. This accomplishment, in collaboration with the Eindhoven University of Technology and the University of L’Aquila, marked a significant leap beyond their previous world record of 10.66 petabits per second.
The breakthrough was made possible by integrating cutting-edge technologies like large-scale Space Division Multiplexing (SDM) and multi-band Wavelength Division Multiplexing (WDM). This successful combination paves the way for the development of ultra-large capacity optical communication networks in the future.

The noteworthy results of this experiment were presented as a post-deadline paper at the 49th European Conference on Optical Communications (ECOC 2023) by Ben Puttnam on Thursday, October 5, 2023.
This achievement represents a major stride towards realizing the potential of future optical communication networks with unprecedented capacity.
