Corning Incorporated (NYSE:GLW) and Alcoa Inc. (NYSE:AA) announced today a strategic agreement for the supply of Corning optical fiber to Alcoa's AFL Telecommunications business through 2005.

AFL Telecommunications will use Corning's optical fiber to manufacture optical ground wire (OPT-GW), all-dielectric self-supporting (ADSS) cable and other fiber-optic cables, primarily for use in networks for the power utility market. The agreement also includes purchase of any new Corning optical fibers as they become commercially available. The two companies have had a long-term supply relationship for more than 15 years.

"This relationship with Corning ensures AFL a strategic long-term position in the fiber-optic cable market," said Frank Larence, president of AFL Telecommunications. "It allows us to support our current solid customer base and ensures our ability to handle future customer needs as demand for fiber-optic cable increases."

Brown, vice president and general manager of Corning Optical Fiber, added, "Corning is proud of its long-standing relationship with AFL Telecommunications, a leader in the fiber-optic industry. AFL was the first manufacturer of optical ground wire cable in the United States and continues to lead both the U.S. and the world in this market. We look forward to continuing to serve AFL and its customers with high-quality Corning fiber and our technological expertise."
