Abstract:
A method for detecting a capacitive load circuit of a remote powered device in a communication system is disclosed. The communication system includes the power source device being coupled to the remote powered device by a cable. the method comprises: providing a first current to the capacitive load circuit of the remote powered device; charging or discharged the capacitive load circuit of the remote powered device according to the first current; and detecting a voltage value or a slope of a first voltage of the capacitive load circuit to generate a detection result. The method further comprises: providing an operation voltage to the remote powered device.
