“In experiments, researchers from the Technical University of Denmark (DTU) and Chalmers University of Technology used the setup to transmit data at 1.84 Pbit/s, encoded in 223 wavelength channels, down a 7.9-km-long (4.9-mile) optical fiber that contained 37 separate cores.”
One laser, one chip, 1.84 petabits a second. The headline leaves out that it needed a special 37-core fiber, and that the run was 7.9 km. Standard fiber in the ground has one core. The record is real, and it is a long way from your street.
