Patent ID: 8427335

Claim:
A physical layer management system comprising: a first jack, the jack having an associated RFID tag and an associated signal generator; a second jack, the second jack having an associated RFID reader; and a patch cord, the patch cord having two plugs, each plug having: a plug antenna and an LED circuit, each LED circuit having a first circuit containing a first light emitting diode (LED) and having a first resonant frequency, and a second circuit containing a second LED and having a second resonant frequency, wherein the first resonant frequency is different than the second resonant frequency, and wherein each LED circuit is electrically connected to the other, each plug antenna is electrically connected to the other, and wherein the signal generator is configured to generate a signal at a frequency of at least one of the first resonant frequency and the second resonant frequency such that the generation of the signal will illuminate at least one of the first LED and the second LED and wherein the RFID tag is configured to send a signal over the patch cord to the RFID reader.
