Nokia, Zayo Europe trial 800Gb/s alien wavelength
April 10, 2025
Nokia and network infrastructure provider Zayo Europe have successfully completed an 800Gb/s alien wavelength trial between Paris and Marseille, spanning over 1,000km.
The live field trial used Zayo Europe’s optical line system and deployed Nokia’s PSE-6s transponders. The setup between Nokia and Zayo Europe increases data-carrying capacity compared to a standard 150GHz WDM (Wavelength Division Multiplexing) channel, improving both efficiency and performance by allowing more data to be transmitted over a single channel.
Michael Katz, Chief Product Officer at Zayo Europe, commented: “As economies continue to digitise, with the EU pushing to supercharge AI capabilities and Europe’s 6G vision, there’s an urgent need for networks that can support these advancements. As a leading network infrastructure provider, we have always been at the forefront of innovation, being the first provider to upgrade its Pan-European network to support 400G client interfaces. This trial with Nokia sets a new industry standard as data centres increasingly mix and match equipment to enhance flexibility, reduce costs, and improve performance.”
Paul Alexander, Vice President and Country General Manager of UK&I at Nokia, added: “At Nokia, we are committed to driving the next generation of network infrastructure by delivering cutting-edge technology that enhances performance, efficiency, and scalability. Our collaboration with Zayo Europe in this live field trial showcases how our PSE-6s technology can seamlessly integrate into existing infrastructures, enabling service providers to meet the evolving demands of a digital economy. With the growing need for high-speed, high-capacity networks to support advancements in AI and 6G, this trial exemplifies the critical role of innovation in helping businesses and data centres stay ahead of the curve.”
