Nokia Bell Labs announced that its researchers set the world record for the highest single carrier bit rate at 1.52 Tbps over 80 km of standard single mode fibre, the equivalent of simultaneously streaming 1.5 million YouTube videos – which is four times the market’s existing approximately 400 Gbps.

The company said this world record, along with other announced optical networking innovations, will further strengthen its ability to create networks for the 5G era that meet the ever-growing data, capacity and latency demands of Industrial Internet of Things (IIoT) and consumer applications.

The highest single-carrier bitrate at 1.52 Tbps was set by a Nokia Bell Labs optical research team led by Fred Buchali. This record was established by employing a new 128 Gigasample/second converter enabling the generation of signals at 128 Gbaud symbol rate and information rates of the individual symbols beyond 6.0 bits/symbol/polarization. This accomplishment breaks the team’s own record of 1.3 Tbps set in September 2019 while supporting Nokia’s record-breaking field trial with Etisalat.
