Alcatel-Lucent and BT test transmission to 1.4 Tbps

Alcatel-Lucent and the British operator BT announced that they had reached in test performed in London, speeds of 1.4 Tbps in optical fiber transmission with spectral efficiency of 5.7 bits per second per Hertz. According to the companies, would be 'the fastest connection ever reached in commercial real hardware environment'. The speed would be equivalent to the transmission of 44 movies in high resolution in one second.

The field test was done in a link of 410 km between the BT Tower in the English capital and the company's research campus in Suffolk fiber. By expanding the density of channels, the experience would have enhanced the efficiency of transmission by 42.5% compared with existing networks.

According to a statement from Alcatel-Lucent, "the increase in capacity occurred with existing optical fiber, potentially reducing the cost of deploying more fiber with the increasing demand for bandwidth."
