Excess radio-frequency (RF) power storage in RF identification (RFID) tags, and related systems and methods are disclosed. The RFID tag is configured to operate with RF power received in wireless RF signals from a RFID tag antenna if received RF power meets or exceeds an operational threshold power for the RFID tag. The RFID tag is also configured to store excess energy derived from excess received RF power in an energy storage device if the received RF power exceeds the operational threshold power for the RFID tag. Thus, when RF power received by the RFID tag is not sufficient for operation, the RFID tag can operate from power provided by previously stored excess energy in the energy storage device.

Optical transmission systems and methods are disclosed that utilize a QSM optical fiber with a large effective area and that supports only two modes, namely the fundamental mode and one higher-order mode. The optical transmission system includes a transmitter and a receiver optically coupled by an optical fiber link that includes at least one section of the QSM optical fiber. Transmission over optical fiber link gives rise to MPI, which is mitigated using a digital signal processor. The QSM optical fiber is designed to have an amount of DMA that allows for the digital signal processor to have reduced complexity as reflected by a reduced number of filter taps as compared to if the DMA were zero.

Excess radio-frequency (RF) power storage and power sharing RF Identification (RFID) tags, and related RFID tag connection systems and methods are disclosed. The excess RF power storage and power sharing RFID tags and related RFID tag connection systems and methods in embodiments disclosed herein allow connected RFID tags to store excess energy derived from excess received RF power in a shared energy storage device. In this manner, an individual RFID tag or a group of connected RFID tags in the RFID tag connection system can continue operation during temporary times when sufficient RF power is not being received from a RFID reader. Sharing stored energy derived from excess received RF power in a shared energy storage device among connected RFID tags in a RFID tag connection system can significantly mitigate problems of RF power interruption.

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.
