Corning and Nortel combine efforts to lower cost of long-haul networks

MARCH 28, 2007 -- By integrating Corning's new ultralow-loss optical fiber technology with Nortel's optical networking equipment, the companies claim to be making it possible for service providers to transmit information over longer distances with less equipment.

MARCH 28, 2007 -- Corning Incorporated (search for Corning) and Nortel (search for Nortel) have announced the development of technologies that improve performance and lower installation and maintenance costs for regional and long-haul networks. By integrating Corning's new ultralow-loss optical fiber technology with Nortel's optical networking equipment, the companies claim to be making it possible for service providers to transmit information over longer distances with less equipment.

In a demonstration at Corning's booth (#2549) at OFC/NFOEC 2007 (from March 27-29), Corning's newly commercialized single-mode fiber with ultralow-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 km, without the use of dispersion compensation equipment or Raman amplification. The configuration showcases the network design flexibility enabled by these products, the companies say.

Nortel's Adaptive All Optical Intelligent solutions featuring Nortel's 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 singlemode fiber with ultralow-loss technology is reportedly the lowest-loss G.652 fiber available with the maximum attenuation available between 0.17 and 0.18 dB/km at 1,550 nm. Capable of extended reach and longer spans, this optical fiber is compatible with the installed base of singlemode fibers and provides the added advantage of ultralow attenuation values at 1,550 nm. Resulting cost savings 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.

"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," says 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 ultralow-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," adds 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."
