QWest heeft in de VS een nieuw snelheidsrecord gebroken met de OC-768 optische technologie van Nortel. Op een lijntje van 700 kilometer werd een snelheid van 40Gbit per seconde bereikt, wat vier keer zo hoog is als de snelste commerciŽle (OC-192) netwerken van dit moment. Met behulp van Dense-Wavelength Division Multiplexing (DWDM) kunnen vier 40Gbps signalen gecombineerd worden om tot een totale bandbreedte van 160Gbps te komen. In het eerste kwartaal van 2001 wil QWest beginnen met brede toepassing van de OC-768 technologie:
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 Ė 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.
[...] 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.
