Abstract
A system and method for continual cable thermal monitoring using cable characteristic considerations in Power over Ethernet (PoE) applications. Cable heating in PoE applications is detected through changes in electrical characteristics of the cable itself. By periodically monitoring the electrical characteristics such as insertion loss or cross talk of the cable, it can be determined whether the cable has exceeded certain thermal operating thresholds.
