| 摘要为满足日益增长的业务需求，光网络需要根据需求进行增长型设计，以提升网络容量和性能。相比现有的光网络中的单芯光纤，多芯光纤可以成倍地提高光纤纤芯密度，为光网络的增长扩容提供更大的容量。该文研究了基于多芯光纤的增长型网络最小成本规划问题，通过建立和求解整数线性规划模型，得到最小新增网络成本和网络设施铺设方案。结果显示：多芯光纤与单芯光纤混合铺设策略可以使新增网络成本达到最小，拓扑增广也可以降低最小新增网络成本。 | |||

| Abstract：Incremental design is needed to increase the network capacity and provide better network performance to satisfy the growing traffic demands in optical networks. Multi-core fibers can multiply the fiber density and provide much more transmission capacity compared with single-core fibers. This article investigates the CapEx minimization problem for multi-core fiber based incremental optical networks. The CapEx-minimized incremental network design is obtained by solving an integer linear programming model of the optimization problem. The results show that properly deploying of both multi-core and single-core fibers and network topology augmentation will minimize the network CapExs. | |||
