| 摘 要： | 光交叉连接(OXC)是波分复用(WDM)全光网的核心节点技术,其结构直接决定了其性能,严格无阻塞是最根本的要求.对于已经提出的多种多样的OXC结构,本文归纳出四种最基本的无阻塞结构,在此基础上具体推演分析其它OXC结构,这样便清晰地论证了OXC结构的阻塞性.对部分阻塞结构提出了消除阻塞的修正方法.

| Abstract: | It is essential that an optical cross-connect (OXC) is strictly-nonblocking on realization of wavelength routing in wavelength-division multiplex all-optical networks.Four kinds of basic nonblocking OXC′s are presented.Some others in various architectures are analyzed and derived on the basis of these four kinds.It is straightforward to prove which are strictly-nonblocking and which are blocking.Methods are given to eliminate the blocking ones. |

| Keywords: | All optical network Wavelength division multiplexing Optical cross connect Blocking |
