Nokia’s 65Tbps Fibre Transmission Sets New Record

Nokia’s Bell Labs has achieved a record-breaking 65Tbps over a 6,600km submarine fibre cable, which is 5Tbps faster than Google’s FASTER Cable undersea installation. The cable used for the record-breaking feat was deployed by Alcatel-Lucent Submarine Networks (ALSN), which is also owned by Nokia following a £11.2 billion takeover last year.

“The future digital existence where everyone, everything and every system and process is connected will require a massive increase in network capacity and the ability to dynamically optimise this capacity,” Marcus Weldon, Nokia CTO and president of Bell Labs, said. “Probabilistic Constellation Shaping extends the limits of current optical transmission by utilising novel modulation techniques to dramatically improve the performance and capacity needed for the new digital era that will be enabled by the Future X Network.”

“This new record is the latest in a long series of achievements by Alcatel-Lucent Submarine Networks over the past 20 years, with breakthroughs that have transformed long distance data transmission,” Olivier Gautheron, CTO of ALSN, added. “It also underlines our strategic focus on R&D to raise the bar for undersea fibre-optic technology as our researchers continue to develop new solutions to help traditional and webscale operators cope with increasing requirements for speed, capacity and cost-effectiveness.”

ALSN has laid over 580,000km of fibre cable around the globe, making it the largest operator of under cabling in the world.
