Prysmian, Nokia Bell Labs and the National Institute of Information and Communications Technology have achieved a record-setting 1 Petabit per second transmission over an optical fiber with standard dimensions. The experiment combines highly spectral efficient wideband optical transmission with an optical fiber guiding 15 spatial modes and the use of specific mode multiplexers. The total capacity of the network has been 1 Petabit per second, corresponding to simultaneous 8K-TV broadcasting for 10 million people.
