ELECTRONIC DEVICE, METHOD OF CONTROLLING POWER SUPPLY, RADIO ON OPTICAL FIBER(ROF) SYSTEM, METHOD OF POWER FEEDING THEREOF AND ROF SUBSCRIBER STATION

摘要

An electronic device, a method for controlling a power supply, an ROF(Radio On Fiber) system, a power supplying method thereof, and an ROF subscriber station are provided to facilitate management for power supplied to multiple electronic devices and use a small inrush current. A switch unit(212) has a control terminal receiving a control signal for turning on an input terminal and an output terminal. A number input part(2111) receives unique ID information assigned to set latency until turn-on of the subscriber station after power is supplied to the subscriber station(2). A timing part(2112) outputs the control signal for turning on the switch to the control terminal after the set latency is passed after timing for starting supplying the power by connecting to the input terminal and a power supply device(213). The latency is set to the longer time than a peak reaching time of the inrush current generated in the device when the switch is turned on. A difference between latencies set by corresponding to each ID number is set to the longer time than the peak reaching time.
