Abstract: In some examples, OTDR event detection and light power level measurement-based fiber optic link certification may include performing, at one end of a device under test (DUT) of a network, a light power level measurement. An OTDR measurement may be performed at the one end of the DUT to detect at least one event associated with the DUT. Based on analysis of the light power level measurement and the OTDR measurement, an event classification may be generated to classify the at least one event associated with the DUT.
