  • Patent number: 10462540
    Abstract: A patch cable and system for interconnecting a pair of terminals, each of the terminals comprising a terminal RFID transponder comprising a unique ID, and for use with a cradle comprising a cradle RFID antenna. The patch cable comprises a pair of connectors, one of the connectors at each end of and interconnected by a guided transmission medium, a connector RFID antenna associated with each of the pair of connectors, a cable RFID transponder positioned along the patch cable between the connectors for communicating with the cradle RFID antenna. When the cable RFID transponder is brought into proximity with the cradle RFID antenna, RF signals emitted by the cradle RFID antenna provide power to and communications with the cable RFID transponder for powering the connector RFID antennas and retrieving the unique IDs of the pair of terminals and communicating the unique IDs to the cradle.
