Abstract
Aspects of the present disclosure describe the localization of a utility pole by distributed fiber sensing of aerial fiber cable suspended from the utility pole.
Claims8
A method for determining a location of a utility pole, the method comprising:
- receiving, from an aerial optical fiber suspended at least in part by the utility pole, an optical signal containing scattering effects resulting from an instant mechanical impact applied to the utility pole;
- identifying, based on the received optical signal containing the scattering effects resulting from the instant mechanical impact applied to the utility pole, a first vibration of the aerial optical fiber due to vibration of the utility pole resulting from the instant mechanical impact applied to the utility pole;
- analyzing, based on the identified first vibration, a location along the length of the optical fiber where the instant mechanical impact applied to the utility pole occurred;
- and
- determining, based on the location along the length of the optical fiber where the instant mechanical impact applied to the utility pole occurred, the location of the utility pole.

A system for determining a location of a utility pole, the system comprising:
- a non-transitory computer readable medium configured to store instructions thereon;
- a DFOS configured to receive from an aerial optical fiber suspended at least in part by the utility pole, an optical signal containing scattering effects resulting from an instant mechanical impact applied to the utility pole, wherein the DFOS connected to the aerial optical fiber;
- a processor connected to the DFOS and the non-transitory computer readable medium, wherein the processor is configured to execute the instructions for:
- identifying, based on the received optical signal containing the scattering effects resulting from the instant mechanical impact applied to the utility pole, a first vibration of the aerial optical fiber due to vibration of the utility pole resulting from the instant mechanical impact applied to the the utility pole;
- analyzing, based on the identified first vibration, a location along the length of the optical fiber where the instant mechanical impact applied to the utility pole occurred;
- determining, based on the location along the length of the optical fiber where the instant mechanical impact applied to the utility pole occurred, the location of the utility pole.
