400GbE-LR8 QSFP-DD compact pluggable interfaces succeed in client-side services trial

April 7, 2020
Windstream Wholesale and Infinera marked an industry-first with their successful trial of LR8-based 400GbE client-side services. The trial was powered by Infinera’s Groove G30 platform.

Windstream Wholesale, a provider of advanced network communications, and Infinera (NASDAQ: INFN) announced that the companies are the first to have successfully demonstrated 400GbE client-side services with ultra-efficient 400GbE-LR8 QSFP-DD compact pluggable interfaces.

The trial leveraged Infinera’s commercially available 2x 600G Wavelength muxponder on its Groove (GX) G30 Compact Modular Platform with the CHM-2T sled, which enabled the customer-facing 400GbE service to be transmitted using a single-carrier 600G wavelength. The achievement enhances Windstream’s ability to meet the ever-expanding bandwidth needs of its largest customers, says the provider.

“We’re excited to partner with Windstream and leverage the power and flexibility of our 600G Wavelength technology to deliver enhanced high-speed services,” commented Glenn Laxdal, SVP, GM of product management, Infinera. “The ability to support 400GbE services with a wide-variety of client interfaces and to carry those services across metro, regional and long-haul distances enables Windstream to seamlessly support their customers’ evolving connectivity needs.”

Windstream Wholesale’s optical infrastructure is engineered to seamlessly support high-speed optical services using the provider's state-of-the-art Flex Grid spectrum and flexible CDC architecture. This enables Windstream to leverage cost-effective 400G today, with 600G and 800G wavelengths in the future.

“Our customers’ bandwidth requirements are growing rapidly, and Windstream is increasing network capacity to meet this demand,” commented Buddy Bayer, chief network officer at Windstream. “Infinera’s GX G30 Compact Modular Platform provides an ultra-efficient transport solution enabling us to offer 400GbE services to support our customers’ high-bandwidth needs. The use of LR8 clients with a single mode fiber interface and a 10-kilometer reach provides an extremely cost-effective solution by enabling us to extend these services directly to our customers’ premises.”

Windstream Wholesale is currently engaging with customers for initial deployment of the end-to-end 400G Wave service. To view the Windstream network map, visit https://www.windstreamenterprise.com/wholesale/interactive-map/
