Systems and methods for improving performance and reliability of a fiber optic network

Abstract

A method of improving performance and reliability of a target fiber optic network is described. The method comprises: (i) observing changes in polarization states (SoP) of light signals in a training fiber optic network; (ii) correlating flap events with a first subset of the changes in polarization states (SoP) of light signals that occur prior to the flap events in the training fiber optic network; (iii) identifying one or more distinct characteristics in the first subset of changes in polarization states in the training fiber optic network that indicate an occurrence of a flap event; (iv) detecting an occurrence of the one or more distinct characteristics in the target fiber optic network; and (v) rerouting network traffic in the target fiber optic network to preemptively avoid a flap event upon detecting the occurrence of the one or more distinct characteristics. Alternatively, the method can comprise correlating the non-occurrence of a flap event with changes in SoP to route network traffic.
