  • Method and apparatus for detecting uncharacteristic power level changes of an optical signal
    Patent number: 9083456
    Abstract: A monitoring apparatus for detecting uncharacteristic short-term power level changes of an optical signal transmitted through an optical fiber, said monitoring apparatus comprising a power level variance calculation unit adapted to calculate a power level variance on the basis of a long-term power level and a current power level of said optical signal and a short-term variance filter adapted to filter transient changes indicated by the calculated power level variance and to generate a trouble occurrence indication indicating an uncharacteristic short-term power level change, if the filtered power level variance exceeds a predetermined power level variance.
    Type: Grant
    Filed: December 4, 2012
    Date of Patent: July 14, 2015
    Assignee: ADVA OPTICAL NETWORKING SE
    Inventors: David Fox, Lawrence T. Dillard, III, Neil Grayson
