ZTE demos WDM transmission via optical spectrum grid

ZTE Corporation has conducted a field demonstration of a 8x216.4Gb/s WDM transmission, through a 50GHz optical spectrum grid.

The demonstration harnessed the Chinese company's high-frequency technology to gain a 200Gb/s polarization multiplexing QPSK signal transmission, at 50GHz through 1,750km of single model fiber optic cable.

The experiment confirms that an upgrade from a 100G transmission system to a 200G system is possible.

ZTE has accomplished various trial network projects in the 100G, and beyond 100G fields, with operators of countries including- China, Germany, Russia and the US.
