800GbE over 1Tbps optical link between London and Chicago

An 800 Gigabit Ethernet (800GbE) service trial connecting London and Chicago across an 8500km subsea and terrestrial route over 1Tbps optical transport, has been set up by Nokia, Windstream Wholesale (WW)and Colt Technology Services.

The trial tested the boundaries of wavelength, capacity, speed and latency. It involved connecting one of Colt’s

five transatlantic subsea cables and part of its terrestrial fibre optic network with Windstream Wholesale’s domestic U.S. low latency, optical fibre Intelligent Converged Optical Network (ICON) monitoring speed and performance.

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

800G doubles capacity to support advanced network applications like AI data center networking, content delivery networks, and financial data hub connections.
