Corning to Present 2005 Optical Fiber Market Overview; Optical Fiber Market Grew 15 Percent in 2005; Fiber-to-the-Home Deployments Continue to Drive Fiber Demand

Business Wire, March 7, 2006

He will add that the company delivered on its promise to develop a new bend-optimized optical fiber for the access segment. "This new fiber is one of the key enablers for products Corning is launching for FTTx applications," Musser will add. "The company also developed a new coating for its optical fiber that is more bend tolerant, another critical feature in today's networks and in new cable designs."

Musser will also point out that Corning made a significant enhancement to LEAF(R) optical fiber, the world's most widely deployed non-zero dispersion-shifted fiber, by further improving the already industry leading polarization mode dispersion (PMD) of the product. This improvement will enable networks to achieve ultra-high data rates.

Finally, Musser will say the company is launching Vascade(R) EX1000 fiber, a new ultra-low loss optical fiber for the submarine market that will enable longer reach and lower network costs. "Corning started the optical fiber industry 35-years ago with the invention of the first low-loss optical fiber for optical communications and today we are launching a fiber with attenuation 100 times lower than that initial fiber," he will say.
