  • SURF and Nikhef complete test with Ciena’s WaveLogic technology showing multiple 1 Terabit paths for scientific research between Amsterdam and Geneva

    SURF and Nikhef complete test with Ciena’s WaveLogic technology showing multiple 1 Terabit paths for scientific research between Amsterdam and Geneva

    SURF, Nikhef and Ciena have successfully tested multiple 1 Tbps paths over fiber between SURF and Nikhef in Amsterdam and CERN in Geneva. The test, powered by Ciena’s WaveLogic 6 Extreme, shows that technological innovations can significantly improve the bandwidth of existing infrastructure.

    A similar development was seen earlier in connections over copper. Where initially only 2,4 kilobits per second was achievable over a classical phone connection, enhanced coding techniques brought this to 50 megabits (VDSL) per second over the same infrastructure. We are seeing the same trend in fiber technology.

    For SURF, this increase in capacity is of great importance. The scientists that SURF supports are able to measure ever more accurately, which leads to explosive growth in the amount of measurement data that SURF has to transport. An example of this is the Large Hadron Collider at CERN, which will be upgraded to much higher precision in the coming years (https://home.cern/science/accelerators/high-luminosity-lhc). 

    SURF and Nikhef together operate a  Tier-1 site for storage and processing of this LHC measurement data. For this purpose, a special 1648 km long fiber path has been established between Geneva and Amsterdam. This trajectory will need to transport much more data in the near future. However, this path also presents a technical challenge due to its long distance, age, fiber type, and the number of small spans that make up this trajectory.

    Vendors of optical equipment continuously come up with improvements for fiber connections like their colleagues did for copper lines in the past. To see what is possible with the most modern optical equipment, SURF and Nikhef therefore regularly conduct trials with these suppliers. In March 2025, we conducted a trial with Ciena over our existing Amsterdam-Geneva connection. In this trial we were able to achieve speeds exceeding 1 Terabit per second over this challenging fiber path. We thank Ciena for the opportunity to do these tests and for its support. These results give us sufficient insights to be sure that at the technical level we can transport the upcoming LHC-data explosion to SURF and Nikhef in Amsterdam.

  • International Collaboration at SuperComputing24: NetherLight/SURF participates in NICT-led experiment to advance high-speed data innovations

    International Collaboration at SuperComputing24: NetherLight/SURF participates in NICT-led experiment to advance high-speed data innovations

    During the SuperComputing 2024 (SC24) event in Atlanta, the Japanese National Institute of Information and Communications Technology (NICT) led an ambitious experiment using a global-scale experimental network. This network, established through collaboration with 19 international partners, connected Tokyo and Atlanta with 10 high-speed 100 Gbps paths, achieving a total capacity of 800 Gbps. The project showcased groundbreaking demonstrations of high-speed data transfer, anonymous communication, and innovative data management.

    One notable highlight was a data transfer experiment that reached 466 Gbps, and an award-winning anonymous communication demonstration by Osaka University achieved 588 Gbps while ensuring robust privacy. 

    NetherLight, the Global Exchange Point (GXP) run by SURF, played a critical role facilitating these complex experiments. Other key contributors included research and education networks and GXP’s from around the world, showcasing the collective effort required to achieve such innovation.

    This NICT experiment at SC24 emphasizes the importance of international collaboration and partnerships in global research and education networks. By working together in experiments like these, we can collectively show and assess the potential for transformative technologies in data handling and communication, essential for future scientific progress.
