Abstract
Net element management system sets test link at optical network link as well as sets loss wave threshold value and loss baseline value. Testing optical power of detecting units positioned at two ends of the detection link calculates out true attenuation value of the detection link. Comparing true attenuation value with the loss baseline value obtains a loss undulating value. Comparing the undulating value with loss wave threshold value obtains state information of the detection link. Adjusting the detection link and forming the detection link groups can control accumulative loss undulating value. The invention provides a method for effective automatic controlling optical power in low cost.
