March 15, 2001
Mar. 15, 2001--Corning Incorporated, a supplier of optical fiber, announced that China Netcom Corporation Ltd. (CNC) has selected Corning as its principal optical fiber supplier.

Corning Incorporated (NYSE:GLW), a supplier of optical fiber, announced that China Netcom Corporation Ltd. (CNC) has selected Corning as its principal optical fiber supplier. Corning will supply more than 500,000 kilometers of LEAF(r) optical fiber over the next three years as part of a long-term supply agreement with the China telecommunications company.

CNC will deploy Corning LEAF fiber in the significant network backbone that will connect 17 major cities across southeast China. During its first phase, the CNC network will contain approximately 12,000 kilometers of cable.

LEAF fiber, an advanced non-zero dispersion-shifted fiber (NZ-DSF), provides networks the lowest cost-per-bit advantage. Its patented large effective area allows higher levels of power to be transmitted through the fiber than standard NZ-DSFs, minimizing the non-linear effects that degrade system performance. LEAF fiber helps decrease the cost of bandwidth.

LEAF fiber continues to be deployed by carriers worldwide, in advanced, high data rate networks on six of the seven continents of the world. Key LEAF fiber customers to date include Aerie Networks, Argus Telecommunications, AT&T, Broadwing Communications, Cable & Wireless, Carrier1, COLT Telecom Group plc, Communications Authority of Thailand, Eurotunnel, Interoute (i-21 network), Impsat, KG Telecom, LD COM, Level 3 Communications, Inc., NEESCom, TransTeleCom, Williams Communications and 360Networks.
