Abstract

Embodiments disclosed in the detailed description include cables and connector assemblies employing a furcation tube(s) for radio-frequency identification (RFID)-equipped connectors, and related systems and methods. In one embodiment, a connector assembly is provided that comprises a cable comprising a cable end, an interior area, at least one communication line, and at least one furcation tube disposed in the interior area. The connector assembly also comprises a connector operably connected to the cable end. At least one antenna wire is configured to be electrically connected to at least one RFID tag to serve as at least a portion of an RFID antenna for at least one RFID tag. At least a portion of the at least one antenna wire is disposed inside the furcation tube in the cable. In this manner, the antenna wire is secured inside the rugged packaging of the cable to protect the antenna wire.

4. The connector assembly of claim 1, wherein the at least one antenna wire is loosely contained inside the at least one furcation tube to accommodate movement of the cable.

5. The connector assembly of claim 1, wherein an inner diameter of the at least one furcation tube is at least −

0.1 millimeters (mm) larger than an outer diameter of the at least one antenna wire.

6. The connector assembly of claim 1, wherein the at least one antenna wire has an exposed section with a length in a range between 7.0 centimeters (cm) and 11.0 cm.

7. The connector assembly of claim 1, wherein at least seventy-five percent (75%) of the length of the at least one antenna wire is disposed inside the at least one furcation tube.

8. The connector assembly of claim 1, wherein the at least one furcation tube resides adjacent to the at least one communication line in the interior area.

9. The connector assembly of claim 1, wherein the at least one RFID tag is included in the connector and is electrically connected to the at least one antenna wire.

10. The connector assembly of claim 9, wherein the at least one RFID tag is comprised of a passive RFID tag.

11. The connector assembly of claim 1, wherein the at least one communication line is comprised of at least one bend-insensitive optical fiber.

12. The connector assembly of claim 1, wherein the at least one antenna wire includes a first wire and the at least one RFID tag includes a first RFID tag, the connector assembly further comprising:

an adapter configured to operably engage with the connector and that includes the first RFID tag and a first electrical contact electrically connected to the first RFID tag; and

a connector electrical contact supported by the connector and electrically connected to the first wire and configured to electrically contact the first electrical contact when the connector and the adapter operably engage so that the first wire serves as at least a portion of the RFID antenna for the first RFID tag.

13. The connector assembly of claim 12, wherein the at least one antenna wire further includes a second wire and the at least one RFID tag includes a second RFID tag, and wherein:

the connector supports the second RFID tag; and

the second wire is electrically connected to the second RFID tag and serves as the portion of the RFID antenna for the second RFID tag.

14. The connector assembly of claim 1, further comprising an adapter configured to operably engage with the connector, and that includes the at least one RFID tag.

15. A telecommunications assembly, comprising:

a plurality of connector assemblies each comprising;

a cable comprising a cable end, an interior area, at least one communication line, and at least one furcation tube disposed in the interior area;

a connector operably connected to the cable end; and

at least one antenna wire configured to be electrically connected to at least one radio-frequency identification (RFID) tag to serve as at least a portion of an RFID antenna for the at least one RFID tag;

wherein at least a portion of the at least one antenna wire is disposed inside the at least one furcation tube;
