摘要
Enter the light pulses in optical fiber and optical waveform based on the way back from the art fiber optic cable rays to examine the optical cable in a meter, type pulse drive signal thereto and a light pulse generating step of generating optical pulses corresponding to light pulses emitted from the optical pulse generation step and enters the optical fiber cable to be inspected, and the light returning from the optical fiber cable and bringing the optical branch step, converting the light taken out by the optical branching step into an electric signal, and this electric signal to the A / D conversion that converts a digital signal phase, the A / D converted digital signal output from step and a processing step of processing the collected signal, if the size of the waveform is collected in the signal processing step is within the first reference value based on the time at which the first time, determines that the optical cable is disconnected and stops the generation of the optical pulses which provides an optical cable and the separation method is determined by the ray of light, characterized in that the instrument comprises a fiber optic cable separation determination step. By determining the separation of the optical cable by a simple method without having to add a special device it is possible to prevent the user's sight damage by the laser diode as a light source.
