OFC/NFOEC 2007 Exhibit to Demonstrate Combined Benefits of
Corning(R) Ultra-low-Loss Optical Fiber Technology with
Nortel's Optical Equipment

    CORNING, N.Y., March 28 /Xinhua-PRNewswire/ -- Corning
Incorporated (NYSE: GLW) and Nortel (NYSE: NT; 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.
