Abstract
In one embodiment, a method for testing a cable includes receiving a read-signal profile read at a receiving-end of a cable upon an initial test signal being input to a sending end of the cable, calculating a cross-correlation function between the read-signal profile and a matched filter output, and determining a peak value of the cross-correlation function. In another embodiment, a system includes a device, the device including logic for receiving a read-signal profile read at a receiving-end of the cable upon an initial test signal being input to a sending end of the cable, logic for calculating a cross-correlation function between the read-signal profile and a matched filter output, logic for determining a peak value of the cross-correlation function, and logic for storing the peak value to a computer readable medium. Other methods, systems, and computer program products are also described according to various embodiments.
