Record-Smashing 43Tbps Transfer Speed Over Single Fiber Achieved
If someone told you this would be possible by now in the mid-aughts you would have laughed.
Using souped-up fiber, the Technical University of Denmark has set a new record for transmitting data over one channel: 43 terabits per second.
The High-Speed Optical Communications group at the university’s photonics engineering department made the transmission. It beat the old record, which belonged to the Karlsruhe Institute of Technology in Germany, by a margin of 11Tbps, the university said.
Faster networks are needed to cope with increasing traffic volumes on new cellular networks, the growing popularity of Wi-Fi, and an increasing dependence on cloud services. On the application side video is also driving demand.
To meet this demand metro networks and the core networks that connect cities, countries and continents have to be upgraded. For example, metro networks are expected to grow 560 percent in total traffic by the end of 2017, according to networking equipment vendor Alcatel-Lucent.
