Nokia Bell Labs broke the fiber optic bitrate record

In the times of COVID-19 pandemic where people are staying more at homes, and schools and universities are closed, the need for greater internet speeds is clear and justified. People are now consuming a lot of data, but after the pandemic is over, a lot of data will still be transmitted through the network infrastructure due to the development of new cloud-based technologies. Back in 2016, Nokia Bell Labs together with Deutsche Telekom T-Labs and the Technical University of Munich achieved a 1 Terabit-per-second transmission rate over optical fiber.
Now, four years later, Nokia Bell Labs announced that its researchers broke the previous record and set a new one for the highest single carrier bit rate at 1.52 Terabits per second (Tbit/s). They managed to do that on a distance of over 80 km on standard single-mode fiber. To put this data in the perspective, the fastest data transfer on the current state-of-the-art network is approximately 400 Gigabits per second.
These are truly great speeds, and together with all the other networking innovations, Nokia will have a more favorable position to develop 5G networks capable of meeting the demands of ever-growing data, bigger network capacity, and low latency requested by the industrial Internet of Things consumers.
