Your home internet is probably getting a few hundred megabits per second, or if you’re really lucky, you might be on a 1-gigabit or even 10-gigabit connection – but 1 petabit is a million gigabits.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.This data transmission speed greatly exceeds the previous record of 1.02 Pbit/s, which was only set in May this year.Using a computational model to scale the data transmission potential of the system, the researchers claim that it could eventually reach eye-watering speeds of up to 100 Pbit/s.“The reason for this is that our solution is scalable – both in terms of creating many frequencies and in terms of splitting the frequency comb into many spatial copies and then optically amplifying them, and using them as parallel sources with which we can transmit data,” said Professor Leif Katsuo Oxenløwe, lead author of the study."
