光传输网(OTN)的技术演进和标准化进展

Advance in Technology Evolution and Standardization of OTN

简单回顾了光纤通信系统的发展历程,指出建设下一代每信道超过100 Gbit/s的高速相干光纤通信系统的必要性和可用技术,列出使用不同的调制和检测技术,每信道100 Gbit/s的WDM系统实现的不同传输容量和频谱效率,介绍了光传输网(OTN)的技术演进、标准化进展和一种可能的OTN复用映射结构。

This paper reviewed the development course for fiber communication systems, pointed out the necessity and enabling technologies for next- generation high-speed coherent optical communica- tion systems targeting beyond 100 Gbit/s per chan- nel listed out the transmission capacity and spectral e^cieney for WDM optical communication systems with the channel rate over 100 Gbit/s when using different advanced modulation formats and detection technologies, and introduced the technology evolu- tion, standard development and hierarchy of OTN.
