Abstract: The invention provides a device for accurately locating ends of cords, wires cables or conduits, in particular in the fields of electricity, electronics, telephone and computer. The device includes an optical fiber disposed on a cord and extending from a first end to a second end of the cord. The optical fiber includes a first fiber end disposed at the first end of the cord and a second fiber end disposed at the second end of the cord. The device further includes a means for injecting light disposed proximate the first fiber end, the first fiber end being accessible so as to be illuminated by the means for injecting light and the second fiber end being accessible so as to recover the light injected at the first fiber end. Said device is useful for locating computer switching cords.

Abstract: The invention concerns a device for accurately locating ends of cords, wires cables or conduits, in particular in the fields of electricity, electronics, telephone and computer. It consists in providing, in or on each cord, (6), wire, cable or conduit, at least an optical fibre (10) extending from one end (7) to the other (8) of the cord (6) or the like. On first end (11) of the optical fibre (10) is accessible at the corresponding end (7) of the cord (6) so as to be illuminated (F) by light injecting means. The second end (12) of the optical fibre (10) is accessible at the other end (8) of the same cord (6), so as to restore (D) the light injected at the first end (7). Said device is useful for locating computer switching cords.
