Corning And Nortel Combine Optical Expertise To Lower Cost Of Long-Haul Netwokr


CORNING, N.Y. – Corning Incorporated (NYSE:GLW) and Nortel* (NYSE/TSX: NT) have developed technologies that improve performance and lower installation and maintenance costs for regional and long-haul networks. By integrating Corning’s new ultra-low-loss optical fiber technology with Nortel’s optical networking equipment, the companies are making it possible for service providers to transmit information over longer distances with less equipment.

Corning and Nortel will demonstrate these advanced long-haul and regional network application products at OFC/NFOEC from March 25-27 in Anaheim, Calif. The demonstration of product solutions will be shown at the Corning exhibit, booth #2549, at the Anaheim Convention Center.

“Working with Corning has yielded a solution aimed at simplifying the deployment and operation of optical networks for customers while providing the foundation for new network services,” said Philippe Morin, president, Metro Ethernet Networks, Nortel. “The ability to transfer information across greater distances with less equipment drives greater simplicity and reliability for operators. Corning shares our commitment to delivering products that enable high performance, inherent flexibility and value for optical networks.”

“Combining Corning ultra-low-loss fiber technology with Nortel’s eDCO and CPL equipment in this demonstration represents a truly flexible solution which can greatly help our customers in building new long-haul networks or reconfiguring their existing networks,” said

Clifford L. Hund, division vice president, sales and marketing, Corning Incorporated. “The integration of these products results in enhanced capability, new design opportunities and cost-savings for customers.”

In the demonstration, Corning’s newly commercialized single-mode fiber with Corning ultra-low-loss technology will be featured in a five span optical system designed with Nortel’s Adaptive All Optical Intelligent network equipment. Several wavelengths will be transported

over five spans, each extending 160 kilometers, without the use of dispersion compensation equipment or Raman amplification. The configuration showcases the network design flexibility enabled by these products.

Nortel’s Adaptive All Optical Intelligent solutions featuring Nortel’s unique electronic Dynamically Compensating Optics (eDCO), enhanced Reconfigurable Optical Add Drop Multiplexer (eROADM) and Domain Optical Controller (DOC), enable faster service turn-up with improved operational efficiency and performance. Using the built-in engineering and planning capabilities of eDCO and CPL equipment, customers can fully compensate for interference from chromatic dispersion electronically, eliminating the need for dispersion compensation equipment and their associated amplifiers, providing network capital and operational expense savings.

Corning’s single-mode fiber with ultra-low-loss technology is the lowest-loss G.652 fiber available with the maximum attenuation available between 0.17 and 0.18 dB/km at 1550 nm. Capable of extended reach and longer spans, this optical fiber is compatible with the installed base of single-mode fibers and provides the added advantage of ultra low attenuation values at 1550 nm. This unique combination allows network designers and operators significant cost saving opportunities that can be leveraged by network operators to upgrade to higher data rates, design longer spans in greenfield deployments or extend the distance between regenerators in existing networks.
