CORNING, N.Y.--(BUSINESS WIRE)--May 30, 2001

Corning Incorporated (NYSE:GLW) announced today that it will collaborate with a number of systems houses at SUPERCOMM 2001 in Atlanta, Georgia, June 5-7 to highlight state-of-the-art metro DWDM solutions demonstrating Corning(R) MetroCor(TM) optical fiber's exceptional system compatibility. Collaborating systems houses include: Astral Point(TM) Communications, Incorporated; Cisco Systems, Incorporated; ONI Systems Corporation; and Sorrento Networks Corporation. The demonstration will be available to attendees during exhibition hours in Corning's booth (#3022).

Curt Weinstein, director, Metro Fiber at Corning Incorporated noted, "As metropolitan networks continue to grow, Corning is increasing its focus on MetroCor fiber's interoperability with a variety of systems. Each of the participating systems houses in this collaborative demonstration has been selected as a strategic provider of metropolitan technology. The SUPERCOMM display speaks directly to our ability to provide a total solution tailored to specific customer needs as we address the increasing need for bandwidth in metropolitan areas."

MetroCor fiber meets the telecommunications industry's needs by enabling metropolitan networks to carry high-density data traffic while reducing complexity and network costs. Allowing for a seamless transition from standard to higher data rate applications, MetroCor fiber is compatible with single-mode fibers. By reducing the electrical regeneration and dispersion compensation required to maintain signal integrity, MetroCor fiber directly addresses the significant bandwidth growth rate that metropolitan areas and private enterprise networks are currently facing.

In addition to the demonstration, a Corning presentation entitled, "Unleashing Metropolitan and Regional Bandwidth: MetroCor(TM) Optical Fiber" will be presented at the SUPERCOMM Exploration Theatre on Wednesday, June 6 at 2:20 - 2:55 p.m. The presentation will address the metropolitan bottleneck, examine economic value and case study results, and present evolving metro networks solutions.
