Abstract

The device includes a connector, a transponder, an optical test unit, an antenna, and a transceiver. The transponder is attached to the connector. The antenna is attached to the optical test unit. The transceiver is electrically connected to the antenna. When the connector is attached to the optical test unit and the optical test unit performs diagnostic testing on the connector and its associated optical fiber, the results or data of the diagnostic testing are stored in the optical test unit for later downloading from the optical test unit to the transponder. The test data can include attenuation loss, insertion loss, and back reflection test data. Once the connector is connected to a host device, the data associated with the specific connector can uploaded from the transponder to the host device.

Claims

1. A device comprising:

a connector;

a transponder attached to the connector;

an optical test unit;

an antenna attached to the optical test unit; and

a transceiver electrically connected to the antenna so as to form a reader which is capable of activating and imparting information to the transponder from the optical test unit.

2. A device according to claim 1 wherein the connector is a fiber optic connector.

3. A device according to claim 2 wherein the information imparted to the transponder includes insertion loss data of the fiber optic connector.

4. A device according to claim 2 wherein the information imparted to the transponder includes attenuation loss data of an optical fiber associated with the fiber optic connector.

5. A device according to claim 2 wherein the information imparted to the transponder includes back reflection data associated with the fiber optic connector.

6. A device comprising:

a connector;

a transponder attached to the connector, the transponder contains test data;

a host device;

an antenna attached to the host device; and

a transceiver electrically connected to the antenna so as to form a reader which is capable of activating and interrogating the transponder when the transponder is sufficiently close to the antenna.

7. A device according to claim 6 wherein the connector is a fiber optic connector.

8. A device according to claim 7 wherein the test data includes insertion loss data of the fiber optic connector.

9. A device according to claim 7 wherein the test data includes attenuation loss data of an optical fiber associated with the fiber optic connector.

10. A device according to claim 7 wherein the test data includes back reflection data associated with the fiber optic connector.
