Nokia, Windstream Wholesale (WW), an optical technology leader in advanced network solutions, and Colt Technology Services (Colt) announced the successful completion of a world-first 800 Gigabit Ethernet (800GbE) service trial connecting London, UK with Chicago, US across an 8500km subsea and terrestrial route over the production network. The trial showcased innovative power-saving networking technologies from the three global tech businesses to test the boundaries of next-generation wavelength, capacity, speed and latency between two of the world’s largest financial trading hubs.
The field trial involved connecting one of Colt’s five powerful transatlantic subsea cables and part of its extensive terrestrial fiber optic network with Windstream Wholesale’s domestic U.S. low latency, optical fiber Intelligent Converged Optical Network (ICON) monitoring speed and performance. Together, Colt and Windstream Wholesale have partnered to demonstrate the world’s first transoceanic 800 gigabit ethernet (GbE) end-to-end service transport from router to router over 1Tbps optical transport. The trial was successfully delivered using Nokia’s pioneering sixth-generation Photonic Service Engine (PSE-6s) coherent optics and 7750 Service Router (SR) high-performance routing platforms boosting internet service speeds and supporting ultra-high wavelength capacity, while maintaining power efficiency.
800G marks a breakthrough in service bandwidth, doubling capacity to support advanced network applications like AI data center networking, content delivery networks, and financial data hub connections.
Buddy Bayer, Chief Operating Officer of Colt Technology Services, said: “Pushing the boundaries of technology innovation is a fundamental part of our customer commitment: it means we stay a step ahead of the market, so we’re ready when our customers ask, “What’s next for us?” This trial has seen us build a powerful industry collaboration to explore the ‘what’s next?’. It’s tested the limits of infrastructure performance and capability across thousands of miles of land and sea with incredible networking technologies, and it’s demonstrated the power and potential of what can be achieved, without skipping a beat.”
Joe Scattareggia, President of Windstream Wholesale, said: “Our latest innovation represents a true game-changer for global connectivity. By partnering with two extraordinary leaders in the industry, we’re enabling unprecedented bandwidth capabilities that are essential for driving AI-powered applications worldwide for our customers. As an optical technology leader, Windstream Wholesale and our partners are establishing 800GbE as the next evolutionary advancement increase for wave services. This collaboration has pushed the boundaries of what’s possible, creating a network solution like no other. Together, we’re not just meeting the demands of the future—we’re shaping it.”
Federico Guillén, President of Network Infrastructure at Nokia, said: “Such an ambitious project — to link two of the world's most important financial hubs — sets the bar very high for network capacity, speed, security and reliability. This demonstration would simply not have been possible without the commitment of Nokia and our partners to the highest standards of innovation in networking technology. Together, we are redefining the art of the possible for IP and optical networks enabling cross-continental subsea and terrestrial communications.”
Following the successful completion of the trial, the organizations are currently exploring options to bring 800GbE connectivity services to market for global business customers.
