CSC, SURF and Nokia Achieve 1.2 Tbit/s Data Transfer to prepare long haul network for new LUMI-AI supercomputer and AI Factories

Nokia, CSC – IT Center for Science, and SURF have successfully tested a high-capacity, quantum-safe fibre-optic connection exceeding 1.2 terabit per second (Tbit/s) between Amsterdam, the Netherlands and Kajaani, Finland with data traversing over 3500 kilometers. The trial, which was conducted in May 2025, demonstrated the potential of ultra-fast, cross-border connectivity for research.

Tests were carried out along several routes, including the longest which spanned 4,700 km through Norway at a capacity of 1Tbit/s. To put this in perspective, 1 Tbit/s is enough to stream 200,000 full HD movies (at 5 Mbit/s each) simultaneously.
