The disclosed systems, and methods for detecting an improper protection in an optical communication network comprising: i) receiving, by a first Coherent-Optical Time Domain Reflectometer (C-OTDR), a first reflected optical signal from a first optical fiber; ii) receiving, by a second C-OTDR, a second reflected optical signal from a second optical fiber; iii) pre-processing, by a processor, the first reflected optical signal and the second reflected optical signal; iv) determining, by the processor, a category of the first C-OTDR and the second C-OTDR; v) depending upon the category of the first C-OTDR and the second C-OTDR, computing a correlation between the first preprocessed reflected optical signal and the second preprocessed reflected optical signal based on a first correlation computation technique or a second correlation computation technique; and vi) based on the computed correlation, detecting the improper protection in the optical communication network.
