城域骨干传送网波分网络结构探讨

由于通信网中宽带数据业务的爆发式增长,导致城域传送网系统容量不断扩大,城域传送网正在面临巨大挑战并迎来大发展机遇。对于城域传送网建设来说,一方面要满足各业务网近期发展的需要,另一方面又要满足城域传送网长期演进的需要。随着100G OTN波分系统的成功商用,OTN波分系统已经成为近期城域骨干传送网建设的首选技术,本文通过对三种波分网络结构的分析,探讨城域骨干传送网波分网络结构的合理性,满足城域传送网建设的长期发展需要。

Because of the broadband data communication network in the explosive growth of the business, lead to rising in metropolitan area transport network system capacity, prompting metropolitan area transport network is facing enormous challenges and usher in the history of the development opportunity. For the construction of metropolitan area transport network, on the one hand, to meet the demand of the recent development of the network, on the other hand, to meet the needs of the long-term evolution of metropolitan area transport network. With 100 g otns wavelength division system of commercial success, otns wavelength division system has become a recent technology of choice for metropolitan area backbone transmission network construction, this article through the analysis of three kinds of wavelength division network structure, discusses the rationality of the metropolitan area network backbone transmission network wavelength division structure, can meet the needs of the long-term development of the metropolitan area transport network construction.
