| The collaborative organisation for IT in Dutch education and research, SURF, has teamed up with Nokia to successfully trial a single-carrier 800Gbps optical transmission over its existing cross-border, multi-supplier research and education fibre network infrastructure in preparation for a higher capacity network that is needed for the forthcoming upgrade to the Large Hadron Collider (LHC) at the CERN particle accelerator, for which it is a contributing research partner.The fibre link is part of the SURF network, which connects national research and education institutes in the Netherlands, such as Nikhef, the Dutch National Institute for Subatomic Physics. Additionally, the SURF network is also connected to other research networks and experiments worldwide, including the LHC Optical Private Network (LHCOPN). The LHCOPN provides access to data at the LHC at CERN, whose discovery of the Higgs boson has revolutionised the world’s understanding of the universe.The trial was conducted over a 1,648km point-to-point fibre link connecting Amsterdam and Geneva, crossing Belgium and France. In it, CERN, Nikhef, SURF and the Atlas LHC experiment – one of two general-purpose detectors at the LHC – collaborated to include real production workflows that are expected when the High-Luminosity Large Hadron Collider (HL-LHC) becomes operational in 2029.The upgrade is intended to provide more insightful research results, improve the potential for ground-breaking discoveries and produce enormous amounts of scientific data. Indeed, the HL-LHC is expected to generate data at a rate of five times the speed of its predecessor. It will depend on advances in SURF’s high-performance network, as demonstrated in this trial, to enable fast and reliable data transfer to the NL T1 for further scientific exploration.Nokia’s sixth-generation super-coherent Photonic Service Engine (PSE-6s) was deployed on the Amsterdam-Geneva link, in combination with SURF’s line system, with equipment from a third party on an older fibre link, achieving 800Gbps transmission using 16QAM-shaped PCS modulation. By focusing on the testing of new technologies with various suppliers, and through the adoption of advanced technology in its network, Nokia said SURF can ensure optimal service and support for the innovative, data-intensive projects of its research partners. -- ???????? | |||
