Abstract
In an example, a method may include a first optical signal and a second optical signal being obtained by a receiving device. The first optical signal may include a first wavelength and the second optical signal may include a second wavelength. The method may also include obtaining a determination that a dynamic anomaly may be present in the transmission medium. In response to the determination that a dynamic anomaly is present in the transmission medium, a relationship between the first optical signal and the second optical signal may be determined to obtain a time delay. The method may include using the time delay, the first wavelength, and the second wavelength to determine an anomaly location in the transmission medium.
