| 摘 要： | 在WDM光网络中，光交叉连接（OXC）节点的串扰是限制网络规模的关键因素，提高光开关的隔离度是降低OXC串扰的一条途径，文章比较了3种不同结构的光开关矩阵的串扰特性，在此基础上对OXC节点进行了优化设计，改进后的OXC节点的串扰性能大的改善，网络规模也因此而得到了极大地扩展。

| Abstract: | The crosstalk of OXC is one of the most important factors which restrict the scale of WDM optical network. One of the methods to reduce the crosstalk of OXC is to reduce the crosstalk of the optical switch array in it. In this paper, the crosstalk of three different kinds of optical switch array were compared. Basing on the design of optical switch array, the structrue of OXC is also designed with less crosstalk. After the optimization, the crosstalk performance of OXC improves greatly, and optical network extend to a large scale. |
