Abstract: A device may utilize a cable that includes connectors and conductors to transfer signals, electrical power, or both. Some cable failures result in an inability to transfer signals. Other failures may result from different cables being used at different times, resulting in a mismatch in which the cable is rated to transfer less power than what could otherwise be delivered by the power source. Parameters, such as cable impedance, transmitter gain, signal conditioning, and so forth that are associated with use of the cable are monitored at different times. If the values of these parameters from one time to another exceed a threshold value, a fault in the cable is determined. A notification about the impending or actual failure of the cable may be presented, and a suitable cable may be recommended for purchase. For example, a hyperlink may be provided to allow for purchase of the suitable cable.
