SURF and ASTRON have implemented the OpenZR+ technology to establish a 400G network connection, significantly enhancing scientific research in the Netherlands. This upgrade enables the transmission of more detailed images of space, which is particularly valuable for astronomers working with the LOFAR telescope. As the world’s largest radio telescope, LOFAR consists of thousands of antennas spread across Europe and can now send more signals simultaneously to its central computer, resulting in faster data processing and higher-quality image outputs.
Thanks to the improved network, astronomers can access real-time scientific data directly. SURF facilitated a direct connection between ASTRON’s research facilities in Groningen and Dwingeloo, increasing the bandwidth from 10 to 400 gigabits per second. This was made possible through 400G-ZR optics, which streamline the network by reducing the need for additional components, resulting in lower power consumption and greater efficiency.
In addition, astronomers can register for multicast streams of data directly from the LOFAR stations via the new network connection. “This provides researchers with direct, real-time access to the latest scientific data, whenever they need it,” says Julian Kootstra, network engineer at ASTRON. “Having your own cluster gives you instant access to new data – a revolutionary way to push the boundaries of our knowledge.”
This technology is part of the broader SURFnet-Infinity strategy, aimed at creating a more flexible and future-proof network for research and education. By adopting open standards, SURF’s network can seamlessly connect equipment from different vendors over long distances, and hereby provide tailored networking solutions for the Dutch research community.
