Abstract
A novel system and apparatus for detecting and locating an external aggression on at least one optical cable of an optical communication system is provided. For example, a signal from a transmitter may be received and analysis may be performed to recover a state-of-polarization (SOP) associated with the signal. A first rapid polarization change that occurs may be identified, which may indicate that an external aggression has occurred on the at least one optical cable. A time offset between the first rapid polarization change and a second rapid polarization change may be used to estimate a location of the external aggression.
