Abstract

An optical-fiber-network (OFN) radio-frequency identification (RFID) system for deploying and/or maintaining an OFN. The system includes a plurality of OFN components, and at least one RFID tag that includes RFID tag data that has at least one property of the OFN component associated with the RFID tag. The RFID tag data is written to and read from the RFID tags prior, during or after deploying the OFN components. An OFN-component-data database unit is used to store and process the RFID tag data. This allows for different maps of the OFN to be made, such as an inventory map and a maintenance map. The OFN-RFID system allows for automated operations and management of OFN components by service personnel, and provides for faster and more accurate OFN system deployment and maintenance.
