The main steps of the inventive method are as follows: feeding a sample signal (SOTDR) into the transmission path (2) using a multiplexer (8) during a current signal transmission and measuring the intensity of said sample signal (SOTDR), which is also coupled out via the multiplexer (8) and is reflected partially at faulty points. Part of the signal to be transmitted (Sin) can also be deviated by means of a coupling device (4) and the intensity of this proportion of the signal (Sup) can be compared with a threshold value. By evaluating the intensities that are measured, it is possible to detect and localise defects in the transmission path (2) or judge the quality of the transmission path (2) without interrupting the transmission.
Le procédé selon l'invention consiste principalement à injecter un signal échantillon (S¿OTDR?) dans la liaison de transmission (2) à l'aide d'un multiplexeur (8) pendant la transmission de signaux en cours ; à mesurer l'intensité de ce signal échantillon (S¿OTDR?) partiellement réfléchi aux discontinuités et également prélevé par le multiplexeur (8). En outre, une partie du signal à transmettre (S¿in?) peut également être dévié par un coupleur (4) et l'intensité de cette partie de signal (S¿up?) peut être comparée à une valeur seuil. L'évaluation des intensités mesurées permettent de détecter et de localiser les défauts de la liaison de transmission (2) sans interrompre le mode d'envoi et de juger de la qualité de la liaison de transmission (2).
