本文分析了全光网中光分插复用节点和光交叉连接节点的同频串扰问题 .同频串扰分为相干串扰和非相干串扰 ,他们对网络性能的影响不同 .我们对节点的同频串扰进行了详细的分析和理论推导 ,并得到了其光功率代价和同频串扰之间的数学关系 .
In this paper, the problem of co-channel crosstalk between optical add / drop multiplexing nodes and optical cross-connect nodes in all optical networks is analyzed.The co-channel crosstalk is divided into coherent crosstalk and non-coherent crosstalk, and their impact on network performance is different. A detailed analysis and theoretical deduction were made and the mathematical relationship between the optical power cost and co-frequency crosstalk was obtained.
