CORNING, N.Y.--(BUSINESS WIRE)--March 15, 2001

Corning Incorporated (NYSE:GLW) and Nortel Networks (NYSE:NT) announced today that it will collaborate to present a leading edge Metro DWDM demonstration at the Optical Fiber Conference (OFC 2001) in Anaheim, California. This is the first demonstration of its kind featuring Corning(R) MetroCor(TM) fiber and the Nortel Networks OPTera Metro 5000 optical networking platform operating at 10 Gbps using EA-DFB lasers. The demonstration will showcase an uncompensated reach of 200 km of MetroCor fiber operating in the 1550 nm telecommunications window compared to 100 km with standard single-mode fiber. The demonstration will be available to the public during exhibition hours in Corning's booth (#2638) March 19-22.

The combination of MetroCor fiber and the Nortel Networks OPTera Metro optical networking platform reinforces the capabilities of these two world-renowned technologies. Without the use of electrical conversion to regenerate the signal or dispersion compensation to maintain signal integrity, the combined Corning and Nortel technologies reduce the need for node electronics. This reduction results in substantial savings to network providers that can in turn be passed on to end customers.

Curt Weinstein, director, metro fiber at Corning Incorporated said, "We are excited to have this opportunity to collaborate with Nortel. At the 2000 National Fiber Optic Engineers Conference, Corning and Nortel displayed a truly innovative model operating at 2.5 Gbps for metropolitan networks, and we are excited about the opportunity to showcase the outstanding performance of MetroCor fiber and Nortel's OPTera Metro system operating at 10 Gbps."

Corning MetroCor fiber offers today's metropolitan networks a more cost-effective and less complex option to handling high-density data traffic by reducing or eliminating dispersion issues. Allowing for a seamless transition to higher data rate applications, MetroCor fiber is also compatible with currently deployed single-mode fibers. This product directly addresses the significant growth rate that metropolitan areas and private enterprise networks are currently facing.
