| Abstract: | An OTDR distance error measuring system is developed.It uses an external source to uniform the wavelength to get better uncertainty.The measurement is flexible for using Time Synthesizer.It can get OTDR distance offset correction data and distance scale correction factor.The distance uncertainty of the system is less than 0 2m,distance scale absolute uncertaity is less than 0 2m. |

| Keywords: | OTDR distance error correction data |
