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.

System and method for optical time-domain reflectometry and design data wire testing

A method for wire connectivity testing includes receiving wiring data indicating at least a length of a wire segment of a vehicle from a design database. The method further includes receiving spread-spectrum time-domain reflectometry (SSTDR) data associated with the wire segment from an SSTDR device coupled to an endpoint of the wire segment. The method also includes calculating a distance-to-fault based on the SSTDR data. The method includes comparing the distance-to-fault to the length of the wire segment. The method further includes, in response to the distance-to-fault being less than the length of the wire segment, generating fault data indicating a failure within the wire segment. The method also includes sending the fault data to a user output device.
