A dark fiber design tool for hardware, circuits, and paths is provided. A method can include generating, by a device comprising a processor, a data record comprising properties of a group of hardware elements associated with a wireless communication network; establishing, by the device, a set of rules that define permissible interactions between respective hardware elements of the group of hardware elements based on the data record; building, by the device, a circuit plan associated with the wireless communication network, the circuit plan comprising optical connections between the respective hardware elements of the group of hardware elements as determined based on the data record and the set of rules; and associating, by the device, respective optical wavelength paths with respective ones of the optical connections of the circuit plan further based on the set of rules.
