Standard optical fiber transmits 1.7Tbps over core network

Standard optical fiber transmits 1.7Tbps over core network.

Chinese telecommunications provider ZTE held a field demonstration of an optical network capable of transmitting 1.7Tbps, the company announced today. The network used Wavelength Division Multiplexing to achieve the thousand-gigabit speeds, which separates data into different wavelengths¬†and transmits those wavelengths over the same optical fiber. In ZTE’s demonstration, the company used 8 different channels, each transmitting 216.4Gbps. The transmission was conducted in China over 1,087 miles, on a standard fiber-optic cable.

From the linked article:

ZTE isn’t the only vendor that has conducted demonstrations to show its prowess when it comes to next-generation WDM systems. Last week, ZTE’s Chinese competitor Huawei showed a prototype system that can handle 400Gbps per channel and offer a total capacity of 20Tbps.

I wonder where Tellabs or Lucent equipment is in all of this.
