System and method for optical time-domain reflectometry and design data wire testing
First Claim
1. A system for testing continuity of a cable assembly, the system comprising:
- an optical time domain reflectometry (OTDR) device configured to selectively couple to an input connector of one of a plurality of cables via a switching matrix;
a design database storing cable data, the cable data indicating at least a length of the cable, a connector, and a pin, wherein the cable data further indicates pathways of cables within vehicles;
a processor and memory in communication with the processor, the processor configured to execute instructions stored on the memory which cause the processor to;
receive a user input via an input device indicating a vehicle, a connector, and a pin;
send a request to a design database identifying the vehicle, the connector, and the pin;
receive the cable data from the design database;
receive OTDR data associated with the cable from the OTDR device;
calculate a distance-to-fault based on the OTDR data;
in response to the distance-to-fault being less than the length of the cable, determine that a connectivity failure has occurred with the cable and generate fault data indicating the connectivity failure; and
generate 3-point vehicle coordinates indicating a position of a failure within the vehicle, wherein the fault data indicating the connectivity failure further includes a numerical representation of the 3-point vehicle coordinates.

Abstract
A system for testing continuity of a cable assembly includes an optical time domain reflectometry (OTDR) device selectively coupled to an input connector of a cable and a design database storing cable data. The cable data indicates at least a length of the cable. The system includes a processor and memory in communication with the processor. The processor is configured to execute instructions stored on the memory which cause the processor to receive the cable data from the design database, receive OTDR data associated with the cable from the OTDR device, and calculate a distance-to-fault based on the OTDR data. In response to the distance-to-fault being less than the length of the cable, the processor determines that a connectivity failure has occurred with the cable and generates fault data indicating the connectivity failure.
