本文对采用锂酸盐光开关和光纤延迟线存储的光时分复用交换结构进行了系统的理论研究。该架构允许利用这些设备的比特率和波长透明性。一种技术，涉及递归定义和证明被用来定义网络，这是数学上相关的Benes和Waksman网络。这产生了与现有的光TDM网络非常不同的架构。它们表现出对组件的经济使用，在某些情况下达到理论最小值。使用前馈而不是反馈延迟，使这些网络具有比现有设计更优越的上级串扰性能和更均匀的衰减。>
A systematic theoretical study of architectures for optical TDM switching, using lithium niobate optical switches and optical fiber delay lines for storage, is undertaken. The architectures allow the bit rate and wavelength transparency of these devices to be exploited. A technique involving recursive definition and proof is used to define the networks, which are mathematically related to Benes and Waksman networks. This produces architectures that are very different from existing optical TDM networks. They exhibit economical use of components, which reaches the theoretical minimum in some cases. The use of feed-forward rather than feed-back delays give these networks superior crosstalk performance and more uniform attenuation than existing designs. >
