Nokia, SURF reach 800 Gb/s transmission on existing fiber

Nokia and SURF have successfully reached a single carrier 800Gb/s optical transmission over SURF’s existing cross border, multi-vendor research and education network infrastructure. The transmission, based on Nokia’s photonic service engine technology, will help accelerate the massive data exchange between the CERN particle accelerator and the NL Tier-1 research IT facilities at SURF and Nikhef, the Dutch National Institute for Subatomic Physics. By reaching 800Gb/s per channel on older fiber varieties, Nokia and SURF prove that existing infrastructure still has tremendous potential, and that legacy optical fibers can be used to meet future capacity demands of the huge data streams generated by international scientific research instruments. The trial was conducted over a 1648 km point-to-point fiber link connecting Amsterdam and Geneva, crossing Belgium and France. The fiber link is part of the SURF-network, which connects national research and education institutes in the Netherlands, such as Nikhef. Additionally, the SURF-network is also well connected to other research networks and experiments worldwide. For this trial, CERN, Nikhef, SURF and the ATLAS LHC experiment have collaborated to include real production workflows that are expected when the High-Luminosity Large Hadron Collider is operational. SURF is preparing its network for CERN’s LHC upgrade to the HL-LHC that will become operational in 2029.
