摘要:
A long haul optical fiber transmission system includes a transmitter having a modulated bit rate of at least 40 Gb/s. A receiver is optically coupled to the transmitter with a composite optical fiber span. The optical fiber includes a first optical fiber coupled to the transmitter and a second optical fiber coupled to the first optical fiber. The first optical fiber has an effective area of at least 120 μm2, an attenuation of less than 0.180 dB/km, and a length L1 from about 30 km to about 90 km. The second optical fiber has an effective area of less than 120 μm2, an attenuation of less than 0.180 dB/km, and a length L2. The sum of L1 and L2 is at least 160 km. The composite optical fiber span does not include a repeater along the length of the span between the transmitter and the receiver or any rare earth dopants.

摘要:
Components having one or more sensors adapted to provide sensor data relating to a condition(s) of the component are disclosed. The component is adapted to communicate with another mating component to associate sensor data with identity information of the mating component. The sensor and identity information can be communicated remotely including via radio-frequency communications employing RF identification devices (RFIDs). Location of the mating component can be determined using the identity information of the mating component. In this manner, the sensor data can be associated with the location of the mating component using the identity information in a “component-to-component” configuration to provide location-specific sensor data. Having the ability to localize sensor data to a specific location can assist in pinpointing areas where performance or other condition issues may exist in a component, a mating component, an article of manufacture associated with the components, and/or communication and/or transmissions lines coupled between components.
摘要:
Protocols, systems, and methods are disclosed for two or more RFID tags to communicate with each other and a device using direct connections. A disclosed system includes a first RFID tag, a second RFID tag, and a device. The first and second RFID tags are configured to mate to each other and directly exchange information. The second RFID tag is further configured to directly exchange information with the device such that information received directly at the second RFID tag from the first RFID tag may then be directly exchanged with the device. The first RFID tag may send a first tag identification directly from the first RFID tag to the second RFID tag. The second RFID tag may then send a first acknowledgement to the first RFID tag if the first tag identification was correctly received by the second RFID tag.

Protocols, systems, and methods are disclosed for two or more RFID tags to communicate with each other using direct connections, wherein the two or more RFID tags are configured to mate and directly exchange identification information. A disclosed method includes detecting that a first RFID tag is connected to a second RFID tag. A first message comprising a first tag identification is sent directly from the first RFID tag to the second RFID tag, and the first RFID tag receives a first acknowledgement from the second RFID tag if the first tag identification was correctly received. A second message comprising a second tag identification may be sent directly from the second RFID tag to the first RFID tag and a second acknowledgement may be received from the first RFID tag if the second tag identification was correctly received.

摘要:
An optical-fiber-network (OFN) radio-frequency identification (RFID) system for deploying and/or maintaining and/or provisioning service and/or locating faults in 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 using one or more mobile RFID readers either prior to, during or after deploying the OFN components. An OFN-component-data database unit is used to store and process the RFID tag data and is automatically updated by the one or more mobile RFID readers. This allows for different maps of the OFN to be made, such as an inventory map and a maintenance map, and for the maps to be automatically updated. The OFN-RFID system allows for mobile automated operations and management of OFN components by service personnel, and provides for faster and more accurate OFN system deployment and maintenance.

摘要:
A passive radio-frequency identification (RFID) system has an RFID reader that communicates with and provides power to an RFID tag. The RFID tag has an RFID integrated circuit chip that contains a memory device for storing information to be transmitted to the RFID reader, and energy storage device that stores energy for powering the integrated circuit chip. In the event that the RFID tag is activated during periods when the RFID integrated circuit chip is not receiving sufficient energy from the RFID reader, then either an energy storage device is provided to allow the activation event to be recorded at the RFID integrated circuit chip, or a memory device is provided that senses and records the activation event and communicates this activation event once power has been restored.
