Abstract:
1. A method, comprising: provisioning an optical module; determining a baseline for a backscatter signal into the optical module based on the provisioning; continuously monitoring the backscatter signal in the optical module during operation of the optical module to detect variances in power of the backscatter signal; and upon detecting a decrease in the power of the backscatter signal below a threshold, performing remedial actions associated with the optical module, wherein the threshold is set indicative of a fiber discontinuity at or near a port of the optical module; wherein the threshold is set based on the backscatter signal being attenuated twice by the fiber discontinuity in that the fiber discontinuity first attenuates an output signal from the optical module and second attenuates the backscatter signal associated with the output signal.
