Abstract

An optical fiber characteristic measuring device includes a light source configured to emit laser light modulated at a predetermined modulation frequency, a photodetector configured to detect Brillouin scattered light obtained by causing the laser light to be incident on a measurement target optical fiber, and a control unit configured to perform control to change a position of a correlation peak by adjusting an amount of delay of the laser light used for detecting the laser light incident on the measurement target optical fiber or the Brillouin scattered light without changing the modulation frequency.
