Fastest Ever Broadband Speed Achieved In A Test In London

Alcatel-Lucent and BT has 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 uncompressed HD films in a single second.

By utilizing a new “flexible grid” infrastructure (Flexgrid) to vary the gaps between transmission channels, the field trial, conducted over an existing fiber link between the BT Tower in London and BT’s Adastral Park research campus in Suffolk, usually set at 50Gigahertz.
