First Demonstration of Terabit Level Transmission over 10,000 Km from a single Laser Source by NEC
NEC has announced the first successful demonstration of 1.15 TB/s ultra-long haul optical transmissions over 10,000 Km distance using optical superchannel technology. The demonstration involved transmission of four superchannel together by wavelength division multiplexing (WDM) in order to achieve a total capacity of 4 Tb/s and a spectral efficiency of 3.6 b/s/Hz all from a single laser source. The demonstration is major step toward practical application of high-capacity transmission for transoceanic communication using cost-effective superchannel technology. Optical superchannels enable efficient bandwidth utilization, resulting in higher spectral efficiency and higher data rate per laser through parallelization. Read more
