Field Verification refers to the process of validating or confirming the accuracy, reliability, or applicability of scientific data, models, hypotheses, or methods by testing or observing them in real-world or natural conditions, as opposed to controlled laboratory settings.
We report the first field verification of fault localization in an optical line system (OLS) by integrating digital longitudinal monitoring and OLS calibration, highlighting changes in physical metrics and parameters. Use cases shown are degradation of a fiber span loss and optical amplifier noise figure.
