Abstract
A method, and optical network management system is provided for monitoring an optical transmission system, including detecting degradation of an electrical signal converted from an optical signal transported via a plurality of optical network elements within the optical transmission system. The method, and optical network management system additionally perform the step of correlating the degradation in the electrical domain with degradation of the optical transmission system in an optical domain based a plurality of threshold values associated with an optical performance parameter corresponding each of the optical network elements. The method, and optical network management system further perform the step of determining whether a cause of the degradation in the electrical domain stems from one or more of the optical network elements according to the correlation.
