BT Trial 5.6Tbps on a Single Optical Fibre and 2Tbps on a Live Core Link

Telecoms operator BT and Chinese technology firm Huawei have announced that they’ve successfully run two new fibre optic network trials, one that delivered 2Tbps (Terabits per second) over a 727km live core network link (London to Dublin) and another that pushed 5.6Tbps via a single optical fibre.

The developments mark a leap forward from the operator’s last closed network trial in October 2014 (here), which at the time claimed to have harnessed a “record spectral efficiency” of 5.97bit/s/Hz in order to deliver super channel speeds of 3Tbps (Terabits per second) over an existing 359km long fibre optic link using commercial grade hardware and software in a real world environment.
