SINGAPORE & CORNING, N.Y.--(BUSINESS WIRE)--June 16, 2002

CommunicAsia2002 exhibit to feature Corning LEAF(R) and SMF-28e(TM)

optical fiber with Nortel Networks OPTera 5100/5200

Corning Incorporated (NYSE:GLW) and Nortel Networks* (NYSE/TSX:NT) are scheduled to demonstrate the integration of their advanced metro/access network application products at CommunicAsia 2002 June 18-21 in Singapore.

These leading optical communications companies will jointly demonstrate an integrated, total network solution to meet the challenges of today's carriers' high-bit rate, metropolitan networks. Utilizing Corning(R) LEAF(R) optical fiber operating in the metro core at 10 Gb/s over Nortel Networks OPTera* Metro 5200 system, the demo will exhibit a significant uncompensated reach advantage in today's metropolitan core architectures. Additionally, in moderate bit-rate, unamplified, metro edge systems, Corning(R) SMF-28e(TM) fiber operating over Nortel Networks OPTera* Metro 5100 system at 1.25 Gb/s for 50 km will demonstrates a versatile, flexible, scalable network architecture.

Various portions of the network demonstration will use Agilent's (NYSE:A) testing and monitoring equipment, which provides the carrier with technically optimized, cost-effective solution. The demonstration will be available to the civilian public during exhibition hours in the Nortel Networks booth (#2K2-01).

"Nortel Networks optical technology is making networks smarter, faster, and more reliable than ever before," said James Demers, Vice President, Optical Internet Asia, Nortel Networks. "By coordinating efforts with companies such as Corning and Agilent, we continue to realize further technological advances in optical communications and bring high-performance, dependable, cost-efficient solutions to our customers."

Added Michael Perry-Jones, senior manager, Marketing and Commercial Operations Asia Pacific, Corning Incorporated, "We are pleased to collaborate with industry leaders like Nortel Networks and Agilent at CommunicAsia. The integration of LEAF and SMF-28e fibers with their innovative metro core and metro edge products results in technologically advanced solutions, which deliver greater network flexibility, enhanced capabilities and cost-savings to the customer."

Nortel Networks OPTera Metro 5200 is protocol and bit-rate independent and dense wavelength division multiplexing (DWDM) data-optimized. It includes a survivable platform with tributary interfaces for metropolitan access and interoffice applications. OPTera Metro 5200 uses DWDM to optimize current fiber infrastructure. It also provides flexible connectivity over point-to-point or ring-based networks, helping service providers to address unpredictable bandwidth growth, capitalize on service delivery opportunities and drive reduced operating costs.

Nortel Networks Metro 5100 Multiservice platform provides the capability to network services across an open, scaleable survivable WDM optical transport platform. Equipped with a bit rate provisionable Universal Optical Interface, the OPTera Metro 5100 can network these services through a single interface. This simplifies the network planning, reduces network-operating costs, and makes rapid delivery of new services a competitive advantage.

LEAF fiber, the world's most advanced non-zero, dispersion-shifted fiber (NZ-DSF), has a large effective area to allow higher levels of power to be transmitted through the fiber than standard NZ-DSFs, minimizing the non-linear effects that degrade system performance. SMF-28e fiber, an extension of Corning's standard single-mode product line, boasts superior low water peak performance with specified performance covering a broad operating spectrum from 1285 nm to 1625 nm.
