In this paper, we propose a static lightpath establishment method to design low‐power all‐optical networks under the constraint of four‐wave mixing (FWM). Since the FWM causes nonlinear interchannel crosstalk, it degrades the communication quality of optical signals. The FWM crosstalk effect becomes strong in a fiber as the number of passing optical signals increases. Therefore, we should reduce the number of optical signals passing through the same fiber from the perspective of the FWM. Meanwhile, in order to enhance the power efficiency of optical amplifiers, which are deployed at each optical fiber, it is preferred that multiple optical signals are transmitted in the same fiber. In order to decrease the power consumption while keeping high communication quality, the proposed method statically selects routes, wavelengths, and fibers for each traffic demand, considering the FWM crosstalk effect and the usage efficiency of the optical amplifiers. We show the performance of the proposed method through numerical experiments.

四波混频约束下的低功率全光网络设计

在本文中，我们提出了一种静态光路建立方法，以在四波混频（FWM）的约束下设计低功率全光网络。由于FWM会引起非线性的通道间串扰，因此会降低光信号的通信质量。随着通过的光信号数量的增加，FWM串扰效应在光纤中变得更强。因此，从FWM的角度来看，我们应该减少通过同一根光纤的光信号的数量。同时，为了提高部署在每条光纤上的光放大器的功率效率，优选在同一根光纤中传输多个光信号。为了降低功耗并保持较高的通信质量，该方法静态选择了路由，波长，考虑到FWM串扰效应和光放大器的使用效率，从而满足每种流量需求的光纤和光纤。我们通过数值实验证明了该方法的性能。
