Lifecycle management of faults occurring on optical fibers

摘要

According to the present invention, a device (46) for tracking the life cycle of a failure occurring in an optical fiber is provided. The device comprises a first detector (21) configured to detect (1) a first fault parameter (7) on the occurrence of a first fault on the optical fiber from the received signal power (5) . The device comprises a database (23) configured to store (6) a first fault parameter and a second fault parameter (12) relating to recovery of a second fault on the optical fiber from a received signal power And a second detector (22) configured to detect (26) from the first detector (5). The device compares (13) the stored fault parameter (25) and the second fault parameter (12), and if the first fault parameter (7) most closely matches the second fault parameter (12) , Further comprising a comparator (24) configured to determine that the first obstacle has been resolved.
