1. A fiber network operation apparatus comprising:
a determination unit configured to determine, for a flow in which an input node and an output node are defined and which is generated on a space division multiplexing-based fiber network, a physical path supporting connection of the flow; and
an allocation unit configured to allocate, in relation to an optical resource that is a combination of a wavelength and a core identified to be allocable to the physical path, the optical resource to the physical path according to predefined resource allocation condition,
wherein, when transmission of optical data and qubits is required on the space division multiplexing-based fiber network, the determination unit is configured to determine the physical path based on giving priority to transmission of qubits, and the allocation unit is configured to include, in the optical resource allocated to the physical path, a combination of at least some cores, among all cores, in which an optical amplifier is not installed.
