PROBLEM TO BE SOLVED: To perform highly accurate measurement of cut-off wavelength in an optional higher mode while reducing the influence of light intensity in a basic mode.;SOLUTION: A higher mode cut-off wavelength measurement system E of the present invention includes: a higher mode exciter 1 which receives an input light from a white light source E1 as a light having a basic mode, outputs an output light to an optical fiber to be measured E2 not as the light having the basic mode but as a light having a higher mode, and converts the input light from the white light source E1 which is input as the light having the basic mode into the output light to the optical fiber to be measured E2, the output light being output as the light having the higher mode; and an optical spectrum analyzer E3 which measures cut-off wavelength of the light having the higher mode in the optical fiber to be measured E2 by measuring dependence of loss on wavelength used in the optical fiber to be measured E2.;COPYRIGHT: (C)2014,JPO&INPIT
