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。
Propose and analyze the structure of reducing crosstalk node of integrated optical add / drop multiplexing / optical cross-connect (OADM / OXC). In the wavelength division multiplexing (WDM) optical transport network, all-in-one nodes can complete the uplink and downlink and cross-connect functions of optical channels simultaneously. Compared with the traditional structure node, this structure uses a set of 1 × 2 and 2 × 1 optical switches and a small-scale optical cross-connect array to realize the optical channel up and down and cross connection. The simulation results show that the power cost due to the same frequency crosstalk in this structure is significantly reduced.
