Abstract :
The method presented showed that the optical time domain reflectometry can be used to facilitate the maintenance of multistaged tree-structured passive optical networks at a lowcost. This method has been implemented in a user-friendly software, and the results obtained proved its effectiveness. We also showed that it is possible to estimate the loss of a fault only on the basis of OTDR traces acquired at the network´s head despite the fact that such traces result in the combination of the reflected and backscattered signals coming from the different optical paths.
