  NEC and Corning Achieve Record-Breaking Results in Optical Transmission

IRVING, Texas & CORNING, N.Y. -- January 16, 2013

NEC Corporation of America (NEC), a leading provider and integrator of
advanced IT communications, managed services, biometric solutions and
carrier-class communications products for optical networks, and Corning
Incorporated (NYSE:GLW), a leading provider of optical fibers, today announced
that NEC and Corning achieved record-breaking results in transmission capacity
over optical fibers. The result was reported at the 2012 Frontiers in
Optics/Laser Science XXVIII (FiO/LS) meeting.

Researchers from the NEC Labs in Princeton, NJ, and from Corning’s Sullivan
Park Research Center in Corning, NY, successfully demonstrated ultra-high
speed transmission with a capacity of 1.05 Petabit/s (10^15 bits per second)
over novel multi-core fiber (MCF) that contains 12 single-mode and two
few-mode cores by employing the advanced space division multiplexing (SDM)
scheme and optical multiple-input multiple-output (MIMO) signal processing

The fiber designed by Corning researchers has cores arranged in a triangular
lattice, which enables transmission over a large number of spatial modes. By
combining spectral multiplexing with polarization and spatial mode
multiplexing and employing multilevel modulation formats, NEC researchers
achieved the total spectral efficiency of 109 bits/sec/Hz, while the aggregate
transmission capacity was 1.050 Petabit/s, which is the highest capacity over
a single optical fiber reported so far.

“This achievement is a continuation of NEC’s leadership in ultra-high optical
transmission systems. We recently demonstrated the highest capacity over
single mode optical fibers, and now we have opened new frontiers with the
highest transmission capacity over any type of optical fibers,” said Dr. Ting
Wang, head of optical networking research at NEC Laboratories America. “We are
proud to lead industry efforts with Corning and to provide solutions that will
be the foundation of the next generation of networking.”

"As the foundation of telecommunications networks, optical fiber innovation
enables carriers to cost effectively keep up with ever-growing traffic
demands," said Cynthia B. Giroux, Division Vice President and Research
Director, Corning Incorporated. “This new advance in optical fibers with 14
transmission cores is a continuation of Corning’s longstanding leadership in
optical fiber innovation."
