【摘要】 提出了一种新的光交叉连接节点结构，分析表明该结构可使连接节点的每条输入光纤里复用的多个光信道能更灵活地选择路由，并交叉连接到指定的输出光纤。PTDS应用软件上仿真结果显示了该结构具有多信道灵活交叉连接功能，同时结构的交叉串扰指标也能达到规定的要求。更多还原

【Abstract】 It is very important of optical cross-connect (OXC) in OTN based on WDM, which is correlated with resource distribution, flexibility, survivability of OTN. A kind of OXC architecture is presented in this paper. The architecture is capable of flexible routing and cross-connecting for optical-channels, which is proved by means of photonic transmission design suite(PTDS) software. The parameters of insertion-loss and cross-talking meet with the requests.更多还原
