Corning and Infinera to Demonstrate Long-Haul Network Design Simplification at OFC/NFOEC 2008

Corning Incorporated (NYSE:GLW) and Infinera (Nasdaq:INFN) will demonstrate how optimal integration of their optical fiber and transmission system products can enable simplified and cost-effective long-haul network designs with two demonstrations at OFC/NFOEC Feb. 26-28, 2008 in San Diego, Calif.

The first demonstration will show how long, un-amplified optical reach enables carriers to significantly reduce amplification requirements and the expenses associated with building and maintaining amplifier huts. In the demonstration, Infinera's Digital Optical Networks technology will transmit and receive data over 320 kilometers (km) of Corning® SMF-28® ULL fiber to demonstrate extended network reach that can eliminate two or three amplification sites traditionally required in a network with 80 or 100 kilometer spans. The long-reach capability results from the combined benefits of Infinera's Raman amplification and the ultra-low attenuation of SMF-28 ULL fiber.

Corning and Infinera will also demonstrate the benefits to carriers and service providers of using lower-cost dispersion compensation equipment. The Infinera DTN will transmit over six 100 kilometer spans of Corning® LEAF® fiber with no in-line dispersion compensation. Link dispersion compensation is achieved through a single dispersion compensation module and advanced electronic dispersion compensation in the receiver terminal on the Infinera line card. Due to the optimized dispersion of LEAF fiber, in-line dispersion compensation is not required.

"We are delighted to work with Corning to show the combined capabilities of two world-class technologies," said Steve Grubb, Infinera's director of optical systems. "The addition of Raman technology to Infinera's Digital Optical Networks solution will enable us to deliver longer reach and new applications, bringing the benefits of Digital Optical Networks to a larger number of applications and more customers than ever before."

"We believe Infinera offers a unique approach that brings new system design opportunities for long-haul customers," said Barry Linchuck, director, worldwide marketing, Corning Optical Fiber. "Our optical fiber products continue to demonstrate long-term and robust performance across new approaches to long-haul system design."

The Raman capability will extend Infinera's digital architecture over ultra-long single-spans, ULH multi-span routes, and hut-skipping applications. With Raman amplification technology, the Infinera DTN can transmit over ultra-long-haul distances of up to 1600 km, enabling cost-effective network designs in networks where very long spans are optimal. Last September, Infinera demonstrated transmission of a signal for 2,000 km in its labs through the use of Raman technology and electronic dispersion compensation in the Infinera DTN platform.

Corning's long-haul optical fiber products, LEAF fiber and SMF-28 ULL fiber, are the industry leaders in total performance. Corning's LEAF fiber is the most widely deployed non-zero dispersion shifted fiber in the world with tens of millions kilometers sold. As long-haul technologies have evolved, Corning has continually improved LEAF fiber and today it continues to demonstrate robust performance in the latest long-haul system designs. Corning SMF-28 ULL fiber is the lowest-loss ITU G.652 fiber available. Capable of extended reach and longer spans, this fiber allows network operators to increase the distance between amplification sites or skip sites all together, providing customers opportunities to reduce capital and operating expenses as well as operation complexity.
