<p>Power sourcing equipment starts power supply after outputting a detection signal to a transmission line and detecting that a powered device is connected with the transmission line. The powered device includes a power storage unit configured to store power obtained from the detection signal output from the power sourcing equipment, and a correction unit configured to correct an impedance unbalance in the transmission line. The power storage unit provides the stored power to the correction unit.</p> |
