Deutsche Telekom researchers break transmission speed record

Researchers at Telekom Innovation Laboratories (T-Labs) have succeeded in realising a 512 Gbit/s transmission over a single optical-fibre wavelength channel for the first time. This corresponds to a usable bit rate of 400 Gbit/s, or the simultaneous transmission of 77 music CDs. While the bar is higher for fibre-optic transmission in a laboratory setting, this record was set under real world conditions in the Telekom optical network on a route of 734 km from Berlin to Hanover and back by speed of light.
