The total throughput reached 128 terabits per second. To put things into perspective, that's the equivalent of simultaneously uploading and downloading 160 full-length 4K movies every second. The results of the test at a distance of more than a thousand kilometers were particularly impressive. The signal traveled this path in just 3.4 milliseconds, while normal fiber takes about five milliseconds. The developers announced a world record for the range of data transmission over hollow optical fibers. Moreover, the experiment was performed on a particularly complex line of hundreds of coils, and not on an existing communication network. According to experts, the technology is in particular demand during the development of artificial intelligence, as remote computing centers need to constantly exchange huge amounts of information. Faster communication can improve the efficiency of such systems and reduce hardware costs. Hollow-core optical fiber has already begun to be used to a limited extent in commercial projects, including the financial communication line between Shenzhen and Hong Kong.
