    摘要: An intermediate power supply unit for distributing lower voltage power to remote devices is disclosed. The intermediate power supply unit includes a higher voltage power input configured to receive power distributed by a power source and a power coupling circuit configured to couple the higher voltage power input to a plurality of power coupling outputs. If it is determined that a wire coupling the power source to the higher voltage power input is touched, the higher voltage power input is decoupled from the power coupling outputs. The intermediate power supply unit also includes a power converter circuit configured to convert voltage on higher voltage inputs to a lower voltage applied to one or more lower voltage outputs. The power converter circuit is also configured to distribute power from the one or more lower voltage outputs over a power conductor coupled to an assigned remote device.

    摘要: Embodiments disclosed in the detailed description include analog distributed antenna system (DAS) supporting distribution of digital communications signals interfaced from a digital signal source and analog radio frequency (RF) communications signals. Analog RF communications signals received from analog RF signal sources are distributed in the analog DAS without being digitized. The analog DAS is also configured to interface with digital signal sources and compatibly distribute digital communications signals. Hence, a digital signal interface in head-end equipment (HEE) is configured to convert downlink digital communications signals to downlink analog RF communications signals for distribution to a plurality of remote units. The digital signal interface is also configured to convert uplink analog RF communications signals to uplink digital communications signals for distribution to the digital signal source(s). By providing the digital signal interface in the HEE, the analog DAS can be configured to distribute digital communications signals to analog DAS components.

    摘要: Power management techniques in distributed communication systems are disclosed. Related components, systems, and methods are also disclosed. In embodiments disclosed herein, the power available at a remote unit (RU) is measured and compared to the power requirements of the RU. In an exemplary embodiment, voltage and current is measured for two dummy loads at the RU and these values are used to solve for the output voltage of the power supply and the resistance of the wires. From at these values, a maximum power available may be calculated and compared to power requirements of the RU.

    摘要: Safety power disconnection for remote power distribution in power distribution systems is disclosed. The power distribution system includes one or more power distribution circuits each configured to remotely distribute power from a power source over current carrying power conductors to remote units to provide power for remote unit operations. A remote unit is configured to decouple power from the power conductors thereby disconnecting the load of the remote unit from the power distribution system. A current measurement circuit in the power distribution system measures current flowing on the power conductors and provides a current measurement to the controller circuit. The controller circuit is configured to disconnect the power source from the power conductors for safety reasons in response to detecting a current from the power source in excess of a threshold current level indicating a load.
