Bell Labs breaks undersea cable speed record

Tuesday 16 July 2013 | 16:21 CET | News
Alcatel-Lucent's Bell Labs unit has broken a new record for the amount of data that can be transmitted over trans-oceanic distances over one optical fibre. In a test carried out at the group's Innovation City campus in Villarceaux near Paris, researchers from Bell Labs successfully sent data at speeds of 31 Tbps over 7,200 km, a capacity three times that of the most advanced commercial undersea cables in use today. The span between amplifiers was 100 km over the whole length. The experiment used 155 lasers, each operating at a different frequency and carrying 200G over a 50GHz frequency grid
