Researchers Claim New Internet Speed Record Of 44.2 Tbps - The Verge:

Researchers based out of Australia's Monash, Swinburne, and RMIT universities say they've set a new internet speed record of 44.2 Tbps, according to a paper published in the open-access journal Nature Communications. That's theoretically enough speed to download the contents of more than 50 100GB Ultra HD Blu-ray discs in a single second.

[...] The test fiber connection ran between RMIT's Melbourne City campus and Monash University's Clayton campus, and the researchers say it mirrors infrastructure used by Australia's National Broadband Network (NBN).

[...] "What our research demonstrates is the ability for fibers that we already have in the ground, thanks to the NBN project, to be the backbone of communications networks now and in the future.

Those speeds were achieved, thanks to a piece of technology called a micro-comb, which offers a more efficient and compact way to transmit data. This micro-comb was placed within the cable's fibers in what the researchers say is the first time the technology has been used in a field trial.

Now, the researchers say the challenge is to turn the technology into something that can be used with existing infrastructure. "Long-term, we hope to create integrated photonic chips that could enable this sort of data rate to be achieved across existing optical fiber links with minimal cost," RMIT's Professor Arnan Mitchell says.
