Introducing new WDM channel into existing infrastructure boosts capacity which the parties claim will be needed for AI and 6G
Nokia and network infrastructure provider Zayo Europe completed an 800Gbps alien wavelength trial between Paris and Marseille – a distance of more than 1,000km. In wave division multiplexing (WDM), an alien wavelength is a coloured optical signal originating from equipment not directly controlled by the network operator, but which is transmitted over existing its existing infrastructure.
Zayo Europe connects more than 600 data centres with a network that spans more than 2.3 million kilometres of fibre and seven subsea cables. It links 17 metro markets across 11 European countries.
Alien integration
Nokia says the trial proves its alien wave technology can be seamlessly integrated into Zayo Europe’s existing infrastructure. The live field trial used Zayo Europe’s optical line system and Nokia’s PSE-6s transponders. It increased the capacity by transmitting more data per WDM channel, compared to a standard 150GHz WDM, thereby improving efficiency and performance.
Michael Katz, Chief Product Officer at Zayo Europe, says: “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…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.”
Era of 6G and AI
Paul Alexander, Vice President and Country General Manager of UK & Ireland at Nokia, said “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.”
