Subsea networks specialist Xtera said it has transmitted 74.38 Tbps over a transatlantic distance, on single mode fibre, creating a record-breaking spectral efficiency of 6.86 b/s/Hz over 6,300 km, across the C and L bands. The experiment was performed with University College London (UCL) using a hybrid distributed-Raman/EDFA amplifier with a bandwidth of 91 nm. This is an adaptation of the technology which Xtera currently deploys in its subsea repeaters.
