Abstract
Provided is a system and associated method for detecting a resistance of a cable. An example method may comprise applying power to a first end of a first and a second conductive pair of the cable, measuring a first voltage across the first end of the first and second conductive pairs of the cable, applying a current source across the first end of a third and a fourth conductive pair of the cable, measuring a second voltage across the current source, and determining a resistance of the cable using the measured first and second voltages. This method may be carried out in a physical arrangement where a second end of the first, second, third and fourth conductive pairs of the cable are connected to a first, a second, a third and a fourth input terminal of a powered device, respectively.
