Windstream Wholesale Successfully Completes 1000km 400G ZR+ Field Trial | Business

LITTLE ROCK, Ark.–(BUSINESS WIRE)–March 8, 2022–

Windstream Wholesale, a leading provider of advanced optical solutions, today announced that it has successfully completed 1000 km 400G field trials using II-VI Incorporated’s (Nasdaq: IIVI) plug-in modules with optics QSFP-DD-DCO which achieve high transmission power of 0dBm. Testing demonstrated unprecedented performance with strong working margins over a production network route and traversing up to 24 ROADMs in a lab environment.

“II-VI’s high transmit power 400G QSFP-DD 0dBm 400G DCO transceivers allow Windstream to deploy greatly simplified network architectures, optically connecting routers directly to access, metro and regional networks without intermediate interfaces overhead, eliminating an entire layer of optical equipment,” said Buddy Bayer, network manager at Windstream. “This revolution in IP over DWDM network architecture delivers significant savings in upfront costs and ongoing expenses, providing Windstream with a highly competitive operating model.”

Windstream Wholesale announced in October that it has partnered with II-VI to co-develop next-generation transceivers that will streamline the deployment of 400 gigabit services while dramatically reducing costs, power consumption and network complexity. II-VI shipped its 400G ZR+ QSFP-DD-DCO transceivers, the world’s first with 0 dBm output power, to Windstream Wholesale for field qualification in February.

During the field trial, Windstream Wholesale established a 400G link over a 1,000+ kilometer link between Phoenix and Los Angeles using II-VI’s 0dBm ZR+ qualifying units with high residual margin k, validating suitability for production use. In particular, this performance was obtained with less than 20 watts of power consumption for each module.

“Our partnership with Windstream on the joint development of the 0dBm 400G ZR+ QSFP-DD-DCO transceivers has enabled II-VI to accelerate technology development, as demonstrated by recent successful field trials,” said Matthias. Berger, Vice President, Coherent Technology, II-VI Incorporated. “Demonstrating interoperability, low power dissipation, and native 0 dBm output is a ‘triple set’ of features that will enable IP-over-DWDM for ROADM-based networks.”

Windstream’s Intelligent Converged Optical Network provides an open, disaggregated network infrastructure, enabling wholesale and enterprise technology customers to select unique custom routes, maintain operational insights with Windstream’s network intelligence capabilities and bring their networks closer to the edge to better serve end users.
