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.
