Denver, June 6, 2000 — Qwest Communications International Inc. (NYSE:Q), the broadband Internet communications company, today announced that its North American broadband network has broken the world Internet land speed record using Nortel Networks (NYSE/TSE: NT) OC-768 (40 Gigabit per second) global optical networking platform. This network trial is the industry's first to carry live commercial traffic at speeds four times faster than any existing commercial network over the longest distance to date – 435 miles (700 kilometers).
In another first, the trial successfully combined four, 40Gbps signals using Dense-Wavelength Division Multiplexing (DWDM) to operate at a total capacity of 160Gbps, all while maintaining the same performance standards of Qwest's commercially-available network. Qwest expects to begin widespread deployment of OC-768 technology in the first quarter of 2001.
"This is another industry first for Qwest as we continue to make advances that benefit our customers," said David Boast, Qwest's executive vice president of planning, engineering, network and operations. "Our network was built from the ground up with the most advanced Internet equipment available, and we continue to identify and accelerate our deployment of next generation technology. This will revolutionize the speed, reliability, quality and economics of the Internet and drive the delivery of advanced broadband applications and services for our customers more quickly."
"We're pleased to have Qwest piloting the industry's highest-capacity Optical Internet solution," said Clarence Chandran, president of the Service Provider and Carrier Group, Nortel Networks. "With this commercial network application, Qwest has validated the new technologies for the Optical Internet, including 40G signal rates, high-speed DWDM, and Raman amplification for long-reach systems."
Nortel Networks' scalable 40 to 80Gbps platform was introduced at Telecom '99 in Geneva last October, where it was the first 80Gbps platform to be demonstrated in a non-laboratory environment. The Nortel Networks global platform, planned for commercial availability in 2001, is expected to have the ability to scale as high as 6.4 terabits per second.
Today's fastest backbone networks operate at OC-192 (10 Gbps) and use DWDM to increase capacity. Nortel Networks' 40 to 80 Gbps scalable platform promises to provide the lowest-cost-per-bit networking capability with high reliability for mission-critical traffic. With the ability to scale both the platform and the number of wavelengths supported on the platform, industry-leading multi-terabit networking will be enabled.
This new technology is also expected to result in significant operational savings, requiring about 75% less space and power in central offices, and equivalent savings in time and effort to provision new customers and services over today's technology. Additionally, Nortel Networks' platform is expected to enable next-generation services such as managed wavelength sales and direct IP over wavelength.
