摘要
随着波分复用(WDM)技术的迅速发展和广泛应用,光网络中交叉连接的规模不断增大,网络结构也越来越复杂。为了降低WDM网络中光域传输和交换的成本,人们提出了波带交换(WBS)技术,并对此进行了大量的研究。文章介绍了部分WBS和多颗粒光交叉连接(MG-OXC)的基本概念,并提出了一种新型的MG-OXC结构。
The rapid advance and extensive applications of WDM technology have brought about a constant increase in the size of the cross-connection in optical works as well as the complexity of their structure. In order to reduce the switching and transmission cost in the optical domain of WDM networks, WaveBand Switching （WBS） has been proposed, for which considerable research has been conducted. In this paper, we introduce some basic concepts of WBS and Multi-Granular Optical Cross-connect （MG -OXC） and present a new type of MG -OXC structure.
