2074935 9209873 PCTABS00013 A method of identifying optical cables by sending optical signals to optical cables C1, C2 via transmission means (device 11), applying an external signal via a signal application device (16) to a particular optical cable C1 that is to be identified, and monitoring a change in the signal by reception detection means (device 11). Harmonic wave signals having a large frequency shift and a large level difference are compared in a relationship between the particular optical cable C1 to which the external signal is applied and the adjacent optical cable C2 neighboring to which the external signal is crosstalking. The particular optical cable C1 is identified without developping any error.
