Abstract

In one embodiment, an autonomous vehicle receives a location of a fiber optic cable repeater of a fiber optic cable. The autonomous vehicle navigates the vehicle to the location of the fiber optic cable repeater and interfaces an optical time domain reflectometer (OTDR) of the autonomous vehicle with an OTDR port of the fiber optic cable repeater. The autonomous vehicle performs OTDR measuring of the fiber optic cable via the OTDR port of the fiber optic cable repeater, and sends a result of the OTDR measuring of the fiber optic cable to a supervisory device.

First claim

What is claimed is:

1. A method comprising:
receiving, at an autonomous vehicle, a location of a fiber optic cable repeater of a fiber optic cable;
navigating, by the autonomous vehicle, the vehicle to the location of the fiber optic cable repeater;
interfacing, by the autonomous vehicle, an optical time domain reflectometer (OTDR) of the autonomous vehicle with an OTDR port of the fiber optic cable repeater;
performing, by the autonomous vehicle, OTDR measuring of the fiber optic cable via the OTDR port of the fiber optic cable repeater; and
sending, by the autonomous vehicle, a result of the OTDR measuring of the fiber optic cable to a supervisory device.

2. The method as in claim 1 , wherein sending the result of the OTDR measuring of the fiber optic cable to the supervisory device comprises:
navigating, by the autonomous vehicle, to the supervisory device; and
uploading, by the autonomous vehicle, the result of the OTDR measuring of the fiber optic cable to the supervisory device.

3. The method as in claim 1 , wherein sending the result of the OTDR measuring of the fiber optic cable to the supervisory device comprises:
wirelessly communicating, by the autonomous vehicle, the result of the OTDR measuring of the fiber optic cable to the supervisory device.

4. The method as in claim 1 , further comprising:
determining, by the autonomous vehicle, whether a break exists in the fiber optic cable adjacent to the fiber optic cable repeater, wherein the result of the OTDR measuring of the fiber optic cable sent to the supervisory device includes an indication of the determined break.

5. The method as in claim 1 , further comprising:
receiving, at the autonomous vehicle, an indication of a location of a potential break along the fiber optic cable from the supervisory device, in response to result of the OTDR measuring sent to the supervisory device.

6. The method as in claim 1 , further comprising:
navigating, by the autonomous vehicle, the vehicle to a location of a potential break along the fiber optic cable; and
generating, by the autonomous vehicle, an indication of the location of the potential break while the vehicle is near or at the location of the potential break.

7. The method as in claim 6 , wherein the indication of the location of the potential break comprises a beam of light emitted by the autonomous vehicle towards the location of the potential break or a captured image of the location of the potential break.

8. The method as in claim 1 , further comprising:
receiving, at the autonomous vehicle, power from the fiber optic cable repeater.

9. The method as in claim 1 , wherein the autonomous vehicle is an unmanned aerial vehicle (UAV) or an unmanned underwater vehicle (UUV).

10. An autonomous vehicle comprising:
an optical time domain reflectometer (OTDR);
a processor coupled to the OTDR and configured to execute a process; and
a memory configured to store the process executable by the processor, the process when executed configured to:
receive a location of a fiber optic cable repeater of a fiber optic cable;
navigate the vehicle to the location of the fiber optic cable repeater;
interfacing, by the autonomous vehicle, the OTDR with an OTDR port of the fiber optic cable repeater;
perform OTDR measuring of the fiber optic cable via the OTDR port of the fiber optic cable repeater; and
send a result of the OTDR measuring of the fiber optic cable to a supervisory device.

11. The autonomous vehicle as in claim 10 , wherein the vehicle sends the result of the OTDR measuring of the fiber optic cable to the supervisory device by:
navigating to the supervisory device; and
uploading the result of the OTDR measuring of the fiber optic cable to the supervisory device.

12. The autonomous vehicle as in claim 10 , wherein the vehicle sends the result of the OTDR measuring of the fiber optic cable to the supervisory device by:
wirelessly communicating the result of the OTDR measuring of the fiber optic cable to the supervisory device.

13. The autonomous vehicle as in claim 10 , wherein the process when executed is further configured to:
determine whether a break exists in the fiber optic cable adjacent to the fiber optic cable repeater, wherein the result of the OTDR measuring of the fiber optic cable sent to the supervisory device includes an indication of the determined break.

14. The autonomous vehicle as in claim 10 , wherein the process when executed is further configured to:
receive an indication of a location of a potential break along the fiber optic cable from the supervisory device, in response to result of the OTDR measuring sent to the supervisory device.

15. The autonomous vehicle as in claim 10 , wherein the process when executed is further configured to:
navigate the vehicle to a location of a potential break along the fiber optic cable; and
generate an indication of the location of the potential break.

16. The autonomous vehicle as in claim 15 , wherein the indication of the location of the potential break comprises a beam of light emitted by the autonomous vehicle towards the location of the potential break or a captured image of the location of the potential break.

17. The autonomous vehicle as in claim 10 , wherein the process when executed is further configured to:
receive power from the fiber optic cable repeater.

18. The autonomous vehicle as in claim 10 , wherein the autonomous vehicle is an unmanned aerial vehicle (UAV) or an unmanned underwater vehicle (UUV).

19. A tangible, non-transitory, computer-readable medium storing program instructions that, when executed by a processor of an autonomous vehicle, causes the processor to perform a process comprising:
receiving, at the autonomous vehicle, a location of a fiber optic cable repeater of a fiber optic cable;
navigating, by the autonomous vehicle, the vehicle to the location of the fiber optic cable repeater;
interfacing, by the autonomous vehicle, an optical time domain reflectometer (OTDR) of the autonomous vehicle with an OTDR port of the fiber optic cable repeater;
performing, by the autonomous vehicle, OTDR measuring of the fiber optic cable via the OTDR port of the fiber optic cable repeater; and
sending, by the autonomous vehicle, a result of the OTDR measuring of the fiber optic cable to a supervisory device.

20. The tangible, non-transitory, computer-readable medium as in claim 19 , wherein the autonomous vehicle is an unmanned aerial vehicle (UAV) or an unmanned underwater vehicle (UUV).
