【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.更多还原
