1. An RFID (radio-frequency identification) tracking system for data center assets for automatically discovering and tracking a configuration of a multiplicity of cables terminated in connectors and connected to one of a multiplicity of numbered connector receptacles, the system comprising:
one or more equipment racks, including networked devices therein with multiple spaced apart connector receptacles therein, each equipment rack having an RFID tracking module operating at a given frequency with an upstream network management interface and a downstream array of short-range RFID readout antenna elements, each antenna element being individually addressable by a multiplexing circuit;
a multiplicity of fiber optic cables, each having a pair of terminating connectors, each cable including an RFID tag with a corresponding tag identifier and with less than 5 mm readout range attached in the vicinity of each said terminating connector;
the array of RFID readout antenna elements attached to equipment or patch panels, such that each short-range antenna element is located in the vicinity of a corresponding numbered connector receptacle and able to read out an RFID tag identifier of any of the multiplicity of cables connected to the corresponding numbered connector receptacle; and
a remote management server for storing data of the RFID tag identifier associated with each of the multiplicity of cables, the identifiers associating each RFID antenna element with a particular numbered connector receptacle,
wherein a volume of an RFID tag is less than 200 cubic millimeters, and
wherein the RFID tags are energized passively by a close-coupled RF excitation signal and comprise an integrated circuit and an inductor and capacitor forming a resonant circuit.
