The planning of optical networks aims to design a configuration that meets the desired requirements while reducing the overall expenses. Many attributes of a network ultimately depend on the underlying physical topology. This work investigates an optimal topology design for given node locations based on a traffic forecast. Our goal is to minimize the total equipment costs, including the dimensioning of node and span capacities. We identify three main cost terms, namely duct costs for the span infrastructure, expenses that can be assigned to the fiber medium, and costs that involve switching functionality. Resilience against single or dual failures is guaranteed by constructing an appropriately meshed network structure that offers path diversity. We develop a mathematical program formulation and investigate a case study.
