The optical branching filter branches modulated light transmitted through the transmission medium to be measured into each optical frequency component of the optical frequency comb. The photodetector detects individually the optical power of each optical frequency component in the branched optical frequency comb. The phase difference detection means mutually compares and detects the phase difference of the frequency f<SB>0</SB>component in the optical power of each optical frequency component. The data processing part calculates the wavelength dispersion value of the transmission medium to be measured from the relation between the phase difference of the frequency f<SB>0</SB>component and the optical frequency of each branched optical frequency component.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
