Verizon and NEC Corporation of America 
have jointly tested ultra-fast optical transmission technology, including 100G, 450G and 1T (1 terabit or 1000G) coexisting on the same fiber. The trial measured the quality of the signal for all channels as well as the intensity of the optical signal. The final determination resulted in the conclusion that these “superchannels” were able to carry higher capacities while improving spectral efficiency without sacrificing distance.
The results of the trial, which was performed last year on 3,560 km (2,212 miles) of field fiber of Verizon’s network in the Dallas area, were outlined in a post-deadline paper that was presented at the recent OFC/NFOEC Conference and Expo.
“As we look to a future when data rates go beyond 100G, it’s important to begin examining how these technologies perform,” said Glenn Wellbrock, director of optical transport network architecture and design at Verizon, and an author of the paper. “This trial gives us a good first step toward analyzing the capabilities of future technologies.”
“NEC is committed to the introduction of ultra-high-speed optical DWDM systems and has an extensive history in achieving the most advanced research and development results in the optical networking area globally,” said Jim Nakajima, senior vice president at NEC. “This joint effort with Verizon demonstrates our capability to introduce novel concepts, confirm their performance, and validate our long-term strategy to service the carrier marketplace with viable high-bandwidth solutions for optical networks.”
The two companies specifically focused on transmission performance over a significant fiber distance since previous experiments of this type have only been performed in a lab environment.http://www.verizon.com http://www.necam.com
