The team that broke the terabit barrier in 2009 is at it again. This time the High-Speed Optical Communications (HSOC) team at the Technical University of Denmark accomplished a record-smashing 43 terabits per second (Tbps) transfer speed over a single optical fiber with just one laser transmitter. That’s equivalent to a transfer rate of around 5.4 terabytes per second. The High-Speed Optical Communications group at the university’s photonics engineering department beat the previous record – 26 terabits per second – set by the Karlsruhe Institute of Technology in 2011. As worldwide Internet traffic grows by 40–50 percent annually, driven by the popularity of cloud services and streamed music and video applications, network vendors are struggling to meet this demand.
