Integrated combs drive extreme data rates

Nature Photonics volume 12, pages 447–450 (2018)Cite this article

A chip-based optical frequency comb source has now been successfully used to send 661 Tbit s–1 over 9.6 km of multicore fibre, bringing considerable savings in the energy consumption and size of data transmission equipment.
