Abstract
Aspects of the subject disclosure may include, for example, obtaining an estimate of a phase of a reference associated with a signal received over an optical channel, obtaining an estimate of a frequency of a carrier associated with the signal, and based on the estimate of the phase of the reference and the estimate of the frequency of the carrier, estimating a location dependent property associated with a disturbance to the optical channel to determine a location estimate for the disturbance. Other embodiments are disclosed.
Claims22
A device, comprising:
- a processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising
- obtaining an estimate of a phase of a reference associated with a signal received over an optical channel,
- obtaining an estimate of a frequency of a carrier associated with the signal, and
- estimating a location dependent property associated with a disturbance to the optical channel to determine a location estimate for the disturbance, wherein determining the location estimate involves one or more calculations that include the estimate of the phase of the reference and the estimate of the frequency of the carrier.
A non-transitory machine-readable medium, storing executable instructions that, when executed by a processing system including a processor, facilitate performance of operations, the operations comprising:
- obtaining an estimate of a phase of a reference associated with a signal received over an optical channel;
- obtaining an estimate of a frequency of a carrier associated with the signal;
- and
- estimating a location dependent property associated with a disturbance to the optical channel to determine a location estimate for the disturbance, wherein determining the location estimate involves one or more calculations that include the estimate of the phase of the reference and the estimate of the frequency of the carrier.
A method, comprising:
- obtaining, by a processing system including a processor, an estimate of a phase of a reference associated with a signal received over an optical channel;
- obtaining, by the processing system, an estimate of a frequency of a carrier associated with the signal;
- and
- estimating, by the processing system, a location dependent property associated with a disturbance to the optical channel to determine a location estimate for the disturbance, wherein determining the location estimate involves one or more calculations that include the estimate of the phase of the reference and the estimate of the frequency of the carrier.
