ZTE Corp., one of China's leading telecommunications equipment providers, has declared that it has set a new world record in single-channel data transmission10Tbps over 640km of optical fiber. According to the company, this rate is equivalent to transmitting 160 high-definition movies per second.

The results of the test transmission were presented at the recent OFC/NFOEC 2011 conference in Los Angeles.

The experiment used ZTE's patented "carrier generation technology" to generate 112 coherent and frequency-locked optical sub-carrier signals, with each sub-carrier bearing 100Gbps optical signals, and successfully achieved optical signals with a single-channel rate of 11.2Tbps, a payload line rate of 10Tbps plus overheads such as FEC.

Optical communications companies are beginning to use 100Gbps transmission but also seeking candidate technologies at higher bit rates of 400Gbps, 1Tbps and beyond. With rapid growth in demand for higher bandwidth, single-channel 10Tbps will be the transmission rate for future telecommunication networks.
