HERNDON, Va. -- NEC Corporation of America (NEC), a premier provider of network, IT and identity management solutions, announced today that NEC, together with AT&T Labs, have successfully demonstrated innovative schemes for modulation and transmission of high speed optical signals at 40 Gb/s and 100 Gb/s data rates. This work was initially described at the Optical Fiber Communication Conference and National Fiber Optic Engineers Conference, February 24-28, 2008.

NEC and AT&T generated multiple wavelength-division-multiplexed (WDM) optical signals, each loaded with 114 Gb/s within a 25 GHz-wide portion of the optical spectrum. This technique resulted in the highest spectral efficiency ever achieved for long-haul optical transmission. The experiment to demonstrate this transmission over 640 km of fiber was performed by NEC Laboratories America in collaboration with AT&T Labs in Middletown, New Jersey.

"NEC enjoys a rich, global Research and Development culture that has kept us at the forefront in this sector," said Dr. Milorad Cvijetic, vice president and chief technology strategist, Optical Network Systems Division, NEC Corporation of America. "We introduced new record-breaking results in transmission of 100G signals, which once again validates our record as one of the premier players in the optical arena."
