DT Breaks Optical Speed Record
Optical fiber forms the backbone of data networks, transporting vast amounts of data between nodes. The maximum bit rate in backbone networks today is 100 Gbit/s per channel. When using all of the channels of an optical fiber, much like a four-lane highway, the new process permits a throughput of up to 24.6 Tbit/s (24,600,000,000,000 bit/s) to be attained on the maximum of 48 available channels (comparable to 48 lanes) of the data highways. A collection of 3,696 CDs could thus be transferred over a single optical fiber - a strand thinner than a human hair - at the same time. With the new method, existing networks can double their current transmission capacity by merely replacing the technology in the terminal stations.
"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," said T-Labs Manager Heinrich Arnold. "With them, we have successfully developed an innovative method by which the transmission capacity of optical fiber can be increased significantly in network operation."
