Deutsche Telekom reveals transmission feat

Deutsche Telekom has become the first company to complete a 512 Gbit/s transmission via a single optical-fibre wavelength channel, it has been revealed.

Researchers at the company's Telekom Innovation Laboratories facility achieved the record-breaking feat, which is the equivalent of a usable rate of 400 Gbit/s or 77 music CDs playing at the same time.

Although higher fibre-optic transmissions have been achieved in an experiment setting in the past, this feat was achieved in real conditions on an optical network route of 734km between Berlin and Hanover and back again.

Optical fibre plays a crucial role in the successful transmission of data networks, with the maximum bit rate currently 100 Gbit/s per channel.

The new process allows up to 24.6 Tbit/s to be transmitted using the maximum of 48 channels on networks.

Telekom Innovation Laboratories manager Heinrich Arnold said: "Together with our technology partner Alcatel-Lucent and the experts at Telekom Network Production, we are very proud of having attained this tremendous transmission performance over the internet under real-world conditions."
