摘要 提出并分析了一体化光分插复用 /光交叉连接 (OADM/OXC)的降低串扰节点结构。在波分复用 (WDM )光传送网络中 ,一体化节点可以同时完成对光通道的上下路与交叉连接功能。与传统结构节点相比 ,该结构中使用一组 1× 2和 2× 1光开关与小规模的光交叉连接阵列实现光通道的上下路与交叉连接。仿真结果证明 ,该结构中由于同频串扰造成的功率代价显著下降。 A low crosstalk structure is proposed and analyzed for the integrative optical add and drop multiplexer/optical cross-connect node (OADM/OXC) that implements the function of both OADM and OXC simultaneously in wavelength division multiplexing (WDM) optical transport networks. For joined adding and dropping, a set of 1 × 2 and 2 × 1 switches are placed before the cross-connect switches instead of using larger dimensional cross-connect array. Simulation result shows that the power penalty can be decreased significantly in the proposed structure.
