| titleOfInvention | Polarization mode dispersion measurement device |
| abstract | (57) [Summary] [PROBLEMS] To enable measurement of polarization mode dispersion in a specific location or a specific transmission path of an optical transmission line formed by laid optical fibers. SOLUTION: A polarization mode dispersion measuring apparatus 10 injects an optical pulse of a predetermined wavelength into an optical transmission line and reflects and scatters reflected light and backscattered light reflected and scattered at connection parts 5, 6 and an optical fiber tip part 7. Based on the returned light, the amplitude values of the p-polarized light component and the s-polarized light component and the phase difference between the p-polarized light component and the s-polarized light component are measured. At this time, the polarization controller 16 changes the polarization state of the optical pulse incident on the optical fiber to be measured to the first. And a second polarization state. The polarization mode dispersion measuring apparatus 10 calculates the amplitude values of the p-polarized light component and the s-polarized light component corresponding to the light pulses in the first and second polarization states, and the phase difference between the p-polarized light component and the s-polarized light component. Are respectively measured, and a predetermined calculation process is performed based on the measured amplitude value and phase difference, to calculate a polarization mode dispersion with respect to an optical pulse having a predetermined wavelength. |
