That new top speed is an insane feat. It's 17,800 times faster than the current fastest internet connections available to consumers – 10 Gb/s in parts of places like Japan, the US and New Zealand. Even NASA can't compete, with its 400 Gb/s ESnet.
It also leaves other experimental devices in the dust, including a photonic chip developed in Australia that clocked a still-impressive 44 Tb/s just a few months ago, and beats the previous record holder – a Japanese team with 150 Tb/s – by almost 20 percent.
"While current state-of-the-art cloud data-centre interconnections are capable of transporting up to 35 terabits a second, we are working with new technologies that utilize more efficiently the existing infrastructure, making better use of optical fiber bandwidth and enabling a world record transmission rate of 178 terabits a second," says Lidia Galdino, lead researcher on the study.
