➀ Nokia, Windstream Wholesale, and Colt Technology Services have established an 800 Gigabit Ethernet (800GbE) service trial between London and Chicago. The trial, spanning an 8500km route, utilizes 1Tbps optical transport. It tests the limits of wavelength, capacity, speed, and latency. The trial connects Colt's transatlantic subsea cable with Windstream Wholesale's domestic U.S. low latency optical network. It employs Nokia's PSE-6s coherent optics and 7750 Service Router platforms. ➁ The 800GbE service doubles the capacity to support advanced network applications such as AI data center networking, content delivery networks, and financial data hub connections.
