| abstract | (57) [Problem] To provide an apparatus capable of measuring chromatic dispersion characteristics and the like with only one fiber pair. SOLUTION: A variable wavelength light source 12 that generates a variable wavelength light whose wavelength can be changed, and a first incident light that modulates the variable wavelength light at a frequency of an input electric signal and enters a first optical fiber line 32. A single optical modulator 15, a first photoelectric converter 22 for photoelectrically converting the first outgoing light transmitted through the first optical fiber line 32, a fixed wavelength light source 21 for generating fixed wavelength light having a fixed wavelength, A power supply (signal source) 25 for generating a reference electric signal having a frequency of, and a second optical modulator 23 for inputting second incident light obtained by modulating fixed wavelength light at the frequency fm of the reference electric signal into a second optical fiber line 34. And a second photoelectric converter 16 that photoelectrically converts the second outgoing light transmitted through the second optical fiber line 34 and outputs the light to the first optical modulator 15. Then, if the photoelectric conversion of the first outgoing light and the reference electric signal are obtained, their phases can be compared to calculate the wavelength dispersion characteristics and the like. |
