ABSTRACT:
A method for identifying optical features along the length of a fiber optic cable in response to injecting a pulse of light into the fiber optic cable and collecting data corresponding to signals which are reflected, the method comprising the steps of: identifying potential optical features in the data according to a first set of parameters; constructing a pattern for selecting optical features from said potential optical features; fitting said pattern to said optical features; determining a position along the cable for each of said optical features; and computing a reflectance/loss level for each of said optical features.
