PPROBLEM TO BE SOLVED: To provide a technology capable of reducing an influence caused by a deterioration in S/N ratio by 4 lightwave mixing and efficiently selecting the wavelength. PSOLUTION: The lightwave network designing apparatus 1 includes: a wavelength-management-order setting means for setting the managing order by lining to manage wavelengths #1, 2, ... for short distance traffic used for transmitting signal, a usable wavelength group having wavelengths #3, 4, 5, ... for long distance traffic, and unusable wavelength #0, ... periodically lined in adjacent manner to the usable wavelength group prohibited from the use, at equal intervals in the order of reducing the influence of noise by 4 lightwave mixing, and selecting an appropriate wavelength on the basis of a distance of the required connection, S/N ratio, and a use state of the wavelength having a possibility of an occurrence of the future influence by 4 lightwave mixing from a lining-order-managed-wavelength group; a connection setting means for setting the connection to the selected wavelength; a wavelength setting control part; and a wavelength use situation DB.
