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.
