Fibre speeds of 1.4Tb/s achieved by BT(British Telecom), Alcatel-Lucent

Alcatel-Lucent and BT achieve fastest real-world fiber speeds of 1.4Tb/s with a world record spectral efficiency of 5.7b/s/Hz over core network.

Paris, January 21, 2014 – Alcatel-Lucent (Euronext Paris and NYSE: ALU) and BT have today announced trial speeds of up to 1.4Tb/s with a record spectral efficiency of 5.7 bits per second per Hertz (b/s/Hz)on an existing core fiber connection. This is believed to be the fastest speed ever achieved in commercial grade hardware in a real-world environment and is equivalent to transmitting 44 HD films in a single second.

The field trial, conducted over an existing fiber link between the BT Tower in London and BT’s Adastral Park research campus in Suffolk, used a new ‘flexible grid’ infrastructure (Flexgrid) to vary the gaps between transmission channels, usually set at 50Gigahertz (GHz). By increasing the density of channels on the fiber, this approach achieved up to 42.5 percent greater…
