15 March 2012, Shenzhen, China – ZTE Corporation ("ZTE") (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global provider of telecommunications equipment and network solutions, announced it has conducted an industry first field demonstration of a 8x216.4Gb/s WDM transmission through a 50GHz optical spectrum grid.
The demonstration utilized patented ZTE high-frequency technology to accomplish a 200Gb/s polarization multiplexing QPSK signal transmission at 50GHz through 1,750km of standard single model fiber optic cable. This resulted in a 25 per cent increase in spectrum efficiency and an increase in transmission efficiency. The experiment proves a seamless upgrade from a 100G transmission system to a 200G system is possible. A record of the demonstration was presented at the OFC/NFOEC 2012 conference.
ZTE is committed to 100G and beyond-100G research. The company was the first in the world to successfully complete a single-channel 11.2Tbit/s optical signal transmission experiment.
ZTE is also an industry leader in next-generation bearer network solutions and high-speed optical communications transmission technology. As such, it was the first company to release whole-course 100G solutions in 2010. The company has completed several trial network projects in the 100G and beyond-100G fields with the mainstream operators from China, Germany, Russia and the United States.
