Abstract

An identification assembly for use with a fiber-optic connector includes a non-conducting over-nut, an electrical assembly disposed at the proximal end of the over-nut, and an RFID tag supported by the distal end of the over-nut. The over-nut is configured to surround and couple with the fiber-optic connector. The electrical assembly includes a first electrical contact configured to electrically connect to the fiber-optic connector, a second electrical contact configured for electrical engagement with a contact portion of a light source assembly, and one or more electrical components coupled between the first and second contacts and providing a defined electrical characteristic. The identification assembly enables identification using either electrical-characteristic based or RFID-based identification approaches.

Claims

1. A fiber optic connector for use with a radiation source assembly having a complementary connector, the fiber optic connector comprising:

an inner connector configured to hold an end of an optical fiber and for positive mechanical and electrical engagement with an engagement portion of the complementary connector to maintain the end of the optical fiber registered to the complementary connector;

a non-conducting over-nut coupled to and surrounding the inner connector;

the over-nut having a proximal end, a distal end, and a central portion separating the distal and proximal ends;

an electrical assembly disposed at the over-nut proximal end, the electrical assembly including

a first electrical contact electrically connected to the inner connector,

a second electrical contact configured for electrical engagement with a contact portion of the complementary connector, and

one or more electrical components electrically coupled between the first and second contacts and contributing to the provision of a defined electrical characteristic between the engagement and contact portions of the complementary connector; and

a radio frequency identification (RFID) tag supported by the over-nut distal end, the over-nut central portion separating the RFID tag from the electrical assembly to prevent the electrical assembly from substantially interfering with communication between the RFID tag and the radiation source assembly.

2. The fiber-optic connector of claim 1, wherein the electrical characteristic is resistance.

3. The fiber-optic connector of claim 1, wherein the inner connector comprises an SMA-style fiber-optic connector.

4. The fiber-optic connector of claim 1, wherein:

the first contact comprises a conductive cylindrical shell coaxial to and interfacing with the inner connector; and

the second contact comprises an annular disk coaxial to and separated from the inner connector.

5. The fiber-optic connector of claim 4, wherein:

the over-nut has a annular recess at the over-nut proximal end; and

the electrical assembly is at least partially disposed in the annular recess.

6. The fiber-optic connector of claim 4, wherein the electrical assembly has a substantially cylindrical shape having a length to outer diameter ratio of less than 0.20.

7. The fiber-optic connector of claim 6, wherein the electrical assembly has a substantially cylindrical shape having a length to outer diameter ratio of less than 0.16.

8. The fiber-optic connector of claim 7, wherein the electrical assembly has a substantially cylindrical shape having a length to outer diameter ratio of less than 0.12.

9. The fiber-optic connector of claim 4, wherein the electrical assembly comprises a non-conducting body that supports the first electrical contact, the second electrical contact, and the one or more electrical components.

10. The fiber-optic connector of claim 1, wherein:

the over-nut has a recess at the distal end; and

the RFID tag is disposed within the distal end recess.

11. An identification assembly for use with a connector configured to connect an optical fiber to a radiation source assembly having a complementary connector, the connector being configured to hold an end of the optical fiber and for positive mechanical and electrical engagement with an engagement portion of the complementary connector to maintain the end of the optical fiber registered to the complementary connector, the identification assembly comprising:

a non-conducting over-nut configured to couple to and surround the connector;

the over-nut having a proximal end, a distal end, and a central portion separating the distal end and the proximal end;

an electrical assembly disposed at the over-nut proximal end, the electrical assembly including

a first electrical contact configured to electrically connect to the connector,

a second electrical contact configured for electrical engagement with a contact portion of the complementary connector, and

one or more electrical components electrically coupled between the first and second contacts and contributing to the provision of a defined electrical characteristic between the engagement and contact portions of the complementary connector; and

a radio frequency identification (RFID) tag supported by the over-nut distal end, the over-nut central portion separating the RFID tag from the electrical assembly to prevent the electrical assembly from substantially interfering with communication between the RFID tag and the radiation source assembly.

12. The identification assembly of claim 11, wherein the electrical characteristic is resistance.

13. The identification assembly of claim 11, wherein the fiber-optic connector comprises an SMA-style fiber-optic connector.

14. The identification assembly of claim 11, wherein:

the first contact comprises a conductive cylindrical shell coaxial to and interfacing with the connector; and

the second contact comprises an annular disk separated from the first contact.

15. The identification assembly of claim 14, wherein:

the over-nut has a annular recess at the over-nut proximal end; and

the electrical assembly is at least partially disposed in the annular recess.

16. The identification assembly of claim 14, wherein the electrical assembly has a substantially cylindrical shape having a length to outer diameter ratio of less than 0.20.

17. The identification assembly of claim 16, wherein the electrical assembly has a substantially cylindrical shape having a length to outer diameter ratio of less than 0.16.

18. The identification assembly of claim 17, wherein the electrical assembly has a substantially cylindrical shape having a length to outer diameter ratio of less than 0.12.

19. The identification assembly of claim 14, wherein the electrical assembly comprises a non-conducting body that supports the first electrical contact, the second electrical contact, and the one or more electrical components.

20. The identification assembly of claim 11, wherein:

the over-nut has a recess at the distal end; and

the RFID tag is disposed within the distal end recess.
