Chinese telecommunications provider ZTE have announced today that they held a field demonstration of an optical network capable of transmitting 1.726 Tbps. They used Wavelength Division Multiplexing (WDM) to separate data into different wavelengths (8 different channels, each transmitting 216.4Gbps) and transmitted those wavelengths over the same standard fiber-optic cable over 1750 KM in China.

While the company has no plans to provide a terabit-network, they say the purpose of their experiment was to prove that “a seamless upgrade from a 100G transmission system to a 200G system is possible.”

Pretty interesting stuff.
