摘　　要：为了更经济和更灵活地传送通信业务，在设计用于未来主干传送网的分级光交换节点设备时，必须密切结合业务的特点．本文介绍了一种可用于分级光交换切点的新型的、结合了空分、波分和时分技术的多级可重构光交叉连接器的原理，并给出了第一和第二级的具体结构．这种光交叉连接设备是完全模块化的，可以很容易扩展为ｎｘｎ大规模光交叉连接设备．In order to transport traffics more cost-efficiently and more flexibly,the characteristics of future traffics must be considered seriously when designing multistage optical switching nodes used for backbone transport networks. In this paper,A novel reconfigurable multistage OXC that combined the advantages of three technologies as Space Division Switching (SDS), Wavelength Division Switching (WDS), and Optical Time-Division Multiplexing (OTDM) has been previewed. The structures of the first and second stages of the OXC have been presented. It is fully modularized and very convenient to scaled to nxu large-scale OXCs.
