Claim 13:
14. A system for monitoring a state of a cable, the system comprising:
a plurality of transferometry devices each being capable of injecting a test signal at an injection point of the cable and measuring a signal being propagated in the cable at a measurement point of the cable, the transferometry devices being intended to be positioned along the cable at predetermined positions so as to break down the cable into successive sections;
a control device configured to communicate with the transferometry devices and configured so as to perform at least one transferometry test consisting in injecting a test signal into the cable with a first transferometry device and measuring the test signal after its propagation in the cable with a second transferometry device different from the first transferometry device; and
a post-processing device configured to communicate with the transferometry devices and configured to compare a measured signal to a reference signal to deduce therefrom an indicator of degradation of a cable section disposed between the first transferometry device and the second transferometry device, the control device being configured to control, according to a predefined test procedure, each transferometry device by activating or deactivating the injection of a test signal into the cable with said control device and by activating or deactivating an acquisition of a measurement of a signal being propagated in the cable with said transferometry device,
wherein the control device is configured to simultaneously activate several tests procedures for several sections of the cable, a test procedure comprising successively executing the following commands:
activating the injection of a test signal by a first transferometry device situated at a start of a first section of the cable, and
activating the acquisition of a signal measurement by a second transferometry device disposed at an end of the first section.
