1. Fault-locating equipment for a light wave conductor cable path, wherein at the end of each cable portion to be tested for light passage, there is present a device which couples a signal, fed by a transceiving device into a first light wave conductor of the cable and being of a certain wavelength unambiguously associated with the respective cable portion, out of this light wave conductor and couples it into a second light wave conductor which conducts the signal back to to the transceiving device, characterised thereby, that coupling elements (6, 7), which reflect light signals of the wavelength associated with the respective cable portion and transmit light signals of all other wavelengths, are arranged at the end of each cable portion in the course of both the light wave conductors (3, 4), wherein the light signals reflected at the coupling element (6) in the light signals reflected at the coupling element (6) in the course of the first light wave conductor (3) are guided to the coupling element (7) in the course of the second light wave conductor, reflected at this coupling element (7) and fed into the second light wave conductor (4). |
