Abstract
A length calculation unit calculates, based on a transmission time required for an optical signal transmitted from a first optical transmission apparatus to a second optical transmission apparatus through an optical transmission line to be transmitted through the optical transmission line, a length of the optical transmission line. A wavelength dispersion calculation unit calculates a wavelength dispersion per unit length of the optical transmission line based on a wavelength dispersion of the optical signal received by the second optical transmission apparatus and the length of the optical transmission line. A type determination unit determines a type of the optical transmission line based on information indicating a correspondence relationship between a value of the wavelength dispersion per unit length and the type of the optical transmission line and the calculated wavelength dispersion per unit length of the optical transmission line.
