The trial connected London with Chicago across an 8500km subsea and terrestrial route.

The field trial connected one of Colt’s five transatlantic subsea cables and part of its terrestrial fibre optic network with Windstream’s domestic US optical fibre Intelligent Converged Optical Network (ICON) monitoring speed and performance.

Colt and Windstream Wholesale partnered to demonstrate the world’s first transoceanic 800GbE end-to-end service transport from router to router over 1Tbps optical transport.

The trial used Nokia’s sixth-generation Photonic Service Engine (PSE-6s) coherent optics and 7750 Service Router (SR) high-performance routing platforms.

"800G marks a breakthrough in service bandwidth, doubling capacity to support advanced network applications like AI data centre networking, content delivery networks, and financial data hub connections," Nokia stated in its announcement.

Buddy Bayer, Chief Operating Officer of Colt Technology Services, said the trial has seen the partners 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,” Bayer said.

Joe Scattareggia, President of Windstream Wholesale said the trial 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," Scattareggia said.

"As an optical technology leader, Windstream Wholesale and our partners are establishing 800GbE as the next evolutionary advancement increase for wave services.”

The three partner companies say they are currently exploring options to bring 800GbE connectivity services to market for global business customers.
