Abstract

The location and power loss of anomalies along an optical link are determined from a distance-wise signal power profile along the optical link and a reference signal power profile. A distance-wise power difference profile between the reference signal power profile and the signal power profile is calculated. A derivative of the power difference profile is calculated. An anomaly indicating a power loss in the optical link is identified from the difference profile. The estimated location of the anomaly is determined from the derivative. An estimated power loss of the anomaly is determined from the difference profile and the estimated location.
