Corning Introduces Newest InfiniCor� Multimode Fiber

Corning will host technical demonstration of newest product offering at 2005 Winter BICSI

CORNING, N.Y., January 21, 2005 � Corning Incorporated (NYSE:GLW) announced today the availability of InfiniCor� eSX+ optical fiber, an extended reach, 10 Gigabit Ethernet-capable multimode fiber for premises networks. Corning will demonstrate the capabilities of this new fiber in a technical display at the 2005 Winter BICSI Conference in Orlando, Florida, on Jan. 23 and Jan. 24.  
 
InfiniCor eSX+ fiber is a 50/125 micron multimode fiber enabling 10 Gb/s serial transmission over extended distances in the 850 nm wavelength window, where low-cost vertical cavity surface emitting lasers (VCSELs) enable a cost-effective, high-bandwidth solution. InfiniCor eSX+ fiber is ideally suited for local area networks, storage area networks and high-speed parallel interconnects for head ends, central offices and data centers. It is optimized for high-performance protocols, such as 10 Gigabit Ethernet, and is also fully compatible with legacy enterprise and local area networks (LANs).  
 
"Our customers and channel partners have recently shown interest in a Corning-qualified extended reach, 10 Gigabit Ethernet-capable multimode fiber." said David Velasquez, global product line manager, multimode fiber. "At Corning we continue to focus our development efforts, manufacturing processes and measurement expertise on ensuring high-quality products that meet the needs of our customers, and that have proven functionality in system tests. After more than one year of functionality testing, we're confident that InfiniCor eSX+ fiber will meet those needs, while also meeting the Corning standard of performance. Now, all enterprise and premises network operators can extend the cost-saving opportunities of low-cost 850nm VCSELs into other areas of their network."  
 
Corning, a world-leading supplier of optical fiber, will conduct a live technical demonstration of error-free 10 Gb/s performance over 550 meters of cabled InfiniCor eSX+ fiber at the 2005 Winter BICSI Conference. This will be a demonstration of the capabilities of Corning�s InfiniCor eSX+ fiber in real-world conditions with commercially-available 850 nm VCSEL transceivers, multiple connectors and length configurations. Corning will demonstrate the ability of InfiniCor eSX+ to offer greater flexibility and margin when planning for the ever-growing number of passive connections. The demonstration will be held on Sunday, Jan. 23, and Monday, Jan. 24, in Osceola 5 at the Gaylord Palms Resort in Orlando.
