Nokia Bell Labs claims that its researchers have set the world record for the highest single carrier bit rate at 1.52 Terabits per second (Tbit/s) over 80 km of standard single mode fiber.
The highest single-carrier bitrate at 1.52 Terabits per second 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 Tbit/s set in September 2019 while supporting Nokia’s record-breaking field trial with Etisalat.
Nokia Bell Labs researcher Di Che and team also set a new data-rate world record for directly modulated lasers (DML), which are crucially important for low-cost, high-speed applications such as datacenter connections. The DML team achieved a world record data rate beyond 400 Gbit/s for links up to 15 km.

From the original 45 Megabit-per-second systems to more than 1 Terabit-per-second systems of today – a more than 20,000-fold increase in 40 years – to create the fundamental underpinning of the internet and the digital societies as we know it.
