摘要
介绍了多载波超级通道技术的原理及优势,探讨了超级通道技术的灵活性,分析表明无栅格的超级通道可以提高约25%的光纤频谱利用率。研究目前实现超级通道的两种技术:相干光正交频分复用技术和奈奎斯特波分复用技术,综述了国内外在理论和试验中采用这两种技术实现超级通道的研究进展,指出超级通道技术对下一代OTN技术发展的重要意义。
The principle of multi-carrier superchannels technology and its advantages are introduced, the flex- ibility of superchannels technology is discussed, the analysis shows that the fiber spectrum efficiency can be increased about 25% via gridless superchannels technology. Then coherent optical orthogonal frequency divi- sion multiplexing technology and Nyquist-WDM technology as the two viable ways to implement superchan- nels are studied, and the foreign and domestic research progress of implementing superchannels using the two technologies in theory and experiment is summarized. Finally, the importance of superchannels technology to the development of the next generation OTN technology is pointed out.
