This world record, along with other announced optical network innovations, will further strengthen Nokia's ability to develop 5G-era networks that meet the growing data, capacity, and latency demands of the Industrial Internet of Things and consumer applications.

The highest single-carrier bit rate of 1.52 Terabits per second was set by a Nokia Bell Labs optical research team led by Fred Buchali. This record was achieved using a new 128 Gigasample/second converter, enabling signal generation at 128 Gbaud and data rates exceeding 6.0 bits/symbol/polarization. This accomplishment surpasses the team's own record of 1.3 Tbit/s set in September 2019 and supports Nokia's record-breaking field test with Etisalat.
