Zayo completed an 800G coherent optics live trial with Nokia

Jan. 22, 2024
The two companies transmitted 800Gbps over 1866km using a single wavelength over 23 spans over a C+L WDM line system.

Zayo has completed a live field trial of Nokia’s sixth-generation Photonic Service Engine super-coherent optics (PSE-6s), demonstrating 800 Gbps over a single wavelength from LA to El Paso on an 1866 km link.

Also, the two companies achieved a 1 Tbps transmission on Zayo’s LA to Phoenix route over 1004km, using the Nokia PSE-6s.

The trial used Nokia’s PSE-6s implemented in the 1830 PSI-M compact modular transport platform equipped with production-ready DMAT6 line cards.

Using the latest 6th generation technology, the 800 Gbps transmission represents a tripling reach over current 7nm solutions and sets a new North American distance record over a live network. In addition, the 1 Tbps transmission between LA and Phoenix over 150GHz WDM channels shows the ability to reach even higher capacity per wavelength on high-traffic routes.

“The infrastructure projects we have and continue to complete to advance connectivity between key cities involve the deployment of new 800G and higher-speed routes,” said Aaron Werley, VP of Technology at Zayo. “Nokia's PSE-6s coherent technology allows Zayo to offer ever-increasing commercial Wavelength speeds, including enabling our industry-first Waves on Demand offering, so when customers demand innovative, higher-bandwidth solutions, the capacity is there for them.”

Zayo currently provides services to carriers and enterprises over its 400G network in North America with over 250 points of presence (PoPs), covering the most in-demand centers. As Zayo continues to invest in its optical network to support the transport of new 400GE and 800GE services, the trial performance demonstrates the ability of Nokia’s optical technologies to support all three of these areas by increasing spectral/bandwidth efficiency, enabling high-speed client services, and lowering network power consumption.

Driving 400G and new IP capabilities has been a critical priority for Zayo. 

In July, Zayo released six new 400G routes, providing what it says is better routing performance, stability, high bandwidth, and reduced pricing. Zayo complemented the new 400G routes with IP PoPs, ensuring a more seamless and uninterrupted communication experience. Zayo added 14 neutral data centers in the first quarter and nine in the second quarter across North America.
