LIFE-CYCLE MANAGEMENT OF FAULTS OCCURING ON OPTICAL FIBRES
First Claim
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.

Abstract
The device includes a first detector configured to detect, from received signal power, first fault parameters related to an occurrence of a first fault on this optical fibre. The device further includes a database configured to store the first fault parameters and a second detector configured to detect from the received signal power second fault parameters related to a restoration of a second fault on the optical fibre. The device further includes a comparator configured to compare the second fault parameters with the stored fault parameters and to decide that the fault is resolved if the first fault parameters most closely match the second fault parameters.

2. A method for keeping track of life-cycles of faults occurring in an optical fibre;
- the method comprising the following steps;
detecting first fault parameters from received signal power 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; storing said first fault parameters; detecting second fault parameters from said received signal power 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; comparing said second fault parameters with stored fault parameters including said first fault parameters and deciding that said first fault is resolved if said first fault parameters most closely match said second fault parameters by said comparing. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
