Abstract

One embodiment is directed to a method of reading RFID tags in an interconnection system comprising at least one port. The method comprises initiating a localized read transaction to read any RFID tag attached to a first connector and any RFID tag attached to a second connector inserted into the port. The method further comprises, as a part of the localized read transaction, reading any RFID tag configured to respond to a first type of RFID interrogation signal, wherein the first connector comprises an attached RFID tag that is configured to respond to the first type of RFID interrogation signal; and, as a part of the localized read transaction, reading any RFID tag configured to respond to a second type of RFID interrogation signal, wherein the second connector comprises an attached RFID tag that is configured to respond to the second type of RFID interrogation signal. Other embodiments are disclosed.

Claims

1. A method of reading RFID tags in an interconnection system comprising at least one port at which a connection can be made between a first cable having a first connector associated with a first side of the port and a second cable having a second connector associated with a second side of the port, the method comprising:

initiating a localized read transaction to read any RFID tag attached to the first connector and any RFID tag attached to the second connector;

as a part of the localized read transaction, reading any RFID tag configured to respond to a first type of RFID interrogation signal, wherein the first connector comprises an attached RFID tag that is configured to respond to the first type of RFID interrogation signal; and

as a part of the localized read transaction, reading any RFID tag configured to respond to a second type of RFID interrogation signal, wherein the second connector comprises an attached RFID tag that is configured to respond to the second type of RFID interrogation signal.

2. The method of claim 1, wherein the first type of RFID interrogation signal comprises an RFID interrogation signal that includes a first application family identifier (AFI) value, wherein reading any RFID tag configured to respond to a first type of RFID interrogation signal comprises reading any RFID tag configured to respond to an RFID interrogation signal including the first AFI value;

and

wherein the second type of RFID interrogation signal comprises an RFID interrogation signal that includes a second AFI value, wherein reading any RFID tag configured to respond to a second type of RFID interrogation signal comprises reading any RFID tag configured to respond to an RFID interrogation signal including the second AFI value.

3. The method of claim 1, further comprising, if reading any RFID tag configured to respond to a second type of RFID interrogation signal is not successful, reading any RFID tag configured to respond to a third type of RFID interrogation signal.

4. The method of claim 1, wherein an RFID tag attached to a protective cap is configured to respond to the third type of RFID interrogation signal, wherein reading the RFID tag attached to the protective cap is used to determine if the first or second side of the port is unused.

5. The method of claim 1, wherein the port comprises an adapter comprising a front jack associated with the first side of the port and a rear jack associated with the second side of the port.

6. The method of claim 5, wherein the adapter further comprises a coupling circuit to couple an RFID reader to the first and second RFID tags when the first and second connectors, respectively, are inserted into the first and second sides of the port.

7. The method of claim 6, wherein the coupling circuit comprises first and second pickup coils;

wherein the first pickup coil is configured so that the first RFID tag will be positioned near the first pickup coil when the first connector is inserted into the first side of the port; and

wherein the second pickup coil is configured so that the second RFID tag will be positioned near the second pickup coil when the second connector is inserted into the second side of the port.

8. A system comprising:

an interconnection system comprising a port having a first side and a second side;

a first cable having a first connector comprising a first RFID tag;

a second cable having a second connector comprising a second RFID tag; and

an RFID reader;

wherein the port is configured so that a connection can be made at the port by inserting the first connector into the first side of the port and by inserting the second connector into the second side of the port, wherein the port is configured to communicatively couple the first cable to the second cable;

wherein the RFID reader is configured so that a single localized read transaction can be initiated by a user in order to read both the first RFID tag and the second RFID tag when inserted into the port;

wherein the RFID reader is configured to, as a part of the localized read transaction, read any RFID tag configured to respond to a first type of RFID interrogation signal, wherein the first RFID tag is configured to respond to the first type of RFID interrogation signal; and

wherein the RFID reader is configured to, as a part of the localized read transaction, read any RFID tag configured to respond to a second type of RFID interrogation signal, wherein the second RFID tag is configured to respond to the second type of RFID interrogation signal.

9. The system of claim 8, wherein the first type of RFID interrogation signal comprises an RFID interrogation signal that includes a first application family identifier (AFI) value, wherein the RFID reader is configured to, as a part of the localized read transaction, read any RFID tag configured to respond to an RFID interrogation signal including the first AFI value, wherein the first RFID tag is configured to respond to an RFID interrogation signal including the first AFI value;

and

wherein the second type of RFID interrogation signal comprises an RFID interrogation signal that includes a second AFI value, wherein the RFID reader is configured to, as a part of the localized read transaction, read any RFID tag configured to respond to an RFID interrogation signal including the second AFI value, wherein the second RFID tag is configured to respond to an RFID interrogation signal including the second AFI value.

10. The system of claim 8, wherein the RFID reader is configured to, if the RFID reader is not successful in reading an RFID tag configured to respond to the second type of RFID interrogation signal, read any RFID tag configured to respond to a third type of RFID interrogation signal as a part of the localized read transaction.

11. The system of claim 10, wherein an RFID tag attached to a protective cap is configured to respond to the third type of RFID interrogation signal, wherein reading the RFID tag attached to the protective cap is used to determine if the first or second side of the port is unused.

12. The system of claim 8, wherein the port comprises an adapter comprising a front jack associated with the first side of the port and a rear jack associated with the second side of the port.

13. The system of claim 12, wherein the adapter further comprises a coupling circuit to couple the RFID reader to the first and second RFID tags when the first and second connectors, respectively, are inserted into the first and second sides of the port.

14. The system of claim 13, wherein the coupling circuit comprises first and second pickup coils;

wherein the first pickup coil is configured so that the first RFID tag will be positioned near the first pickup coil when the first connector is inserted into the first side of the port; and

wherein the second pickup coil is configured so that the second RFID tag will be positioned near the second pickup coil when the second connector is inserted into the second side of the port.

15. The system of claim 8, wherein the interconnection system comprises an optical patch panel system configured for use in the outside plant of a telecommunications network.
