Abstract

The invention which is the subject of the present application makes it possible to achieve automatic monitoring systems for fibre optic cables, installed but not yet utilised, which employ a single optical source and a single photodetector, yet allow the checking of an arbitrary number of optical fibres. This result is achieved by the use of directional couplers, optical switches, optical delay lines or special topological configurations which eliminate the risk of unwanted interference effects between coherent signals. <IMAGE>
