Abstract: A method of localizing a defect location and a method of identifying a cause of a defect in an optical transport network (OTN). The method of localizing a defect location in an OTN includes generating tandem connection monitoring (TCM) coordinates consisting of a TCM level and trail information of an optical data unit (ODU) based on a relationship between an OTN line card (LC) and the ODU in the OTN, localizing the defect location in the OTN by converting the TCM level to a segment on the TCM coordinates, and identifying a root cause using a defect identification algorithm that traces back the cause of the defect in an opposite direction to that in which the defect is propagated based on an OTN layer structure.
