1. A device for keeping track of life-cycles of faults occurring in an optical fibre;

  • the device further comprising;

    a first detector configured to detect from received signal power first fault parameters related to an occurrence of a first fault on said optical fibre comprising a degradation in said received signal power, a tolerance on said degradation and a type of said first fault;

    a database configured to store said first fault parameters;

    a second detector configured to detect from said received signal power second fault parameters related to a restoration of a second fault on said optical fibre comprising an increase in said received signal power, a tolerance on said increase and a type of said second fault;

    a comparator configured to compare said second fault parameters with stored fault parameters including said first fault parameters and to decide that said first fault is resolved if said first fault parameters most closely match said second fault parameters by said comparing.
