Nortel (Northern Telecom) First in World to Provided Four-Fiber Rings on 10
Gbps Network Solution
ORLANDO, Fla., Sept. 15 /PRNewswire/ -- Nortel (Northern Telecom) (NYSE: NT, Toronto: NTL), the world's leading supplier of high-capacity optical networking
systems, has delivered another technology breakthrough by supplying bi-directional four-fiber rings for 10 Gbps networks. Nortel four- fiber rings operating at 10 Gbps
have been placed into commercial service and further implementation of this powerful solution, which provides the best reliability available in the industry today, are
anticipated throughout major networks in 1998 and beyond. The application, believed to be the first such demonstration of four-fiber BLSR on a 10 Gbps platform with
32-wavelength Dense-Wavelength Division Multiplexing (D-WDM), is being demonstrated here at the National Fiber Optic Engineers Conference (NFOEC), which
continues until September 17 (Nortel booth No.453).
''Nortel has maintained leadership in 10 Gbps and D-WDM worldwide with more than 90 percent marketshare, throughout the two years since we first introduced our
S/DMS TransportNode OC-192,'' said Mike Unger, president, Optical Networks, Nortel. ''With some 11 major networks having deployed the 10 Gbps solution, it's
evident that many of them will take advantage of the self-restoring capability of our four-fiber rings which provide the kind of service reliability and performance needed
in today's mission critical data and voice communications.''
Nortel's four-fiber rings ride on the optical layer of the network and provide operational simplicity, self-restoration capability in milliseconds, and sophisticated bandwidth
management for least cost per bit operation. By combining its D-WDM technology and its ring expertise, Nortel has derived survivability that is unsurpassed in the
industry.
Along with OC-192/D-WDM market leadership, Nortel is the leader in bi-directional line switched rings (BLSR), a proven and highly cost-effective technology that is
supporting the national backbones of the new millennium.
Nortel already provides the highest capacity per fiber for optical networks of up to 160 Gbps using Dense-Wavelength Division Multiplexing (D-WDM), and has now
doubled that capacity by providing 32 wavelength capability before year end. A number of service providers are preparing to close large SONET BLSR rings to take
advantage of Nortel's total network capacity benefits. Nortel's Integrated Network Management gives those service providers the additional advantage of end-to-end
network management not attainable in hybrid networks.
''Network operators are looking for a robust technology solution that can cost-effectively handle the demanding backbone networking requirements for a wide variety of
services,'' said Unger. ''Given all the technologies available today, the D-WDM OC-192 4-fiber BLSR architecture delivers the lowest cost-per-bit-mile, the best system
performance, ultimate reliability, and network integrity -- all the reasons why the market has clearly endorsed Nortel's OC-192 technology.''
