Identification apparatus of optical cable and identification method
An optical cable identification apparatus for identifying an optical cable by disturbing an optical fiber, existing inside an optical cable desired to be identified, from outside the optical cable. An optical unit transmits two optical signals to a single strand of optical fiber inside the optical cable, and detects a phase difference, a time difference, and light intensity between two optical signals which are reflected due to the disturbance from the outside. A single-fiber ending unit generates the time difference. A signal processing unit removes noise from the two reflected optical signals and demodulates the optical signals. A sound output unit outputs the optical signals from the signal processing unit as sounds.
