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 comprising:
- a memory storing computer-readable instructions; and
a processor configured to execute the computer-readable instructions 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;
store said first fault parameters in a database;
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; and
compare said second fault parameters with stored fault parameters including said first fault parameters and determine that said first fault is resolved in response to said first fault parameters most closely matching said second fault parameters based on 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 fiber. 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 fiber. 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.
