摘　　要：　WDM(波分复用)技术极大地利用了光纤的巨大带宽潜力,为此介绍了一种运用WDM技术的光网络结构,其中心局之间通过光交换设备的控制进行自适应的时分交换,同一中心局内的光交换机之间通过预约的时分复用共享所有可用波长,IP(因特网协议)数据包可以直接在该网络中透明传输。该网络结构具有组网灵活,带宽利用率高,扩容性好以及路由方法简单的优点。WDM technology takes advantage of gigantic bandwidth potential of fiber optics tremendously. Therefore an optical network architecture base on WDM technology is introduced. It carries out self-adaptable TDM switching between central offices through the control of OXC equipment. And the optical exchanges in a same central office can share all the available wavelength channels with a reservation method. IP packets can be transmitted on the network transparently. The network architecture features flexible networking, effective bandwidth usage, easy up-grade, and simple routing algorithm.
