Patent ID: 11201687

Abstract:
[Problem] In a disaggregated optical transmission system formed by connecting bases including transmission apparatuses having specifications of different vendors through an optical fiber, wavelength information is easily set in the transmission apparatuses at both bases of the optical fiber such that the required wavelength is assigned to the optical fiber.[Solution] The optical transmission system 30 includes a facility DB 34 that stores at least information on the NW configuration in which a predetermined optical signal wavelength is assigned to the optical fiber 17, a wavelength assignment unit 32f that, if the facility DB 34 stores no information on the same NW configuration as a NW configuration that the wavelength assignment request to the optical fiber 17 between bases has, associates a management number with a wavelength commonly available for different vendors, based on vendor information in which management numbers and wavelengths of vendors are associated, and further if this wavelength is assignable to the optical fiber 17, performs a wavelength assignment instruction by using the management number, and a wavelength setting unit 33 that performs wavelength assignment setting in the transmission apparatuses at both bases of the optical fiber 17 in response to the wavelength assignment instruction.
