Deutsche Telekom’s research wing has successfully transmitted data over a single optical fibre wavelength at 512Gbps, the company has announced.
The current maximum bit rate for channels operating in backbone networks is 100Gbps. T-Labs working with Alcatel-Lucent said on Friday that the usable bit rate of the new technology would be 400Gbps per channel.
"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 734km from Berlin to Hanover and back by speed of light," Deutsche Telekom said.
As T-Labs’s system allows for up to 48 channels per optical fibre, the new technology should lead to fibre strands with a theoretical maximum throughput of 24.6Tbps.
