Abstract
A PoE midspan injector constituted of: an Ethernet device side data port; a PD side data port; a plurality of pairs of data wires coupling the Ethernet device and PD side data ports; a power reception port; a pair of first type coils; and a pair of second type coils, each second type coil coupled in series to a respective first type coil thereby forming a coil set, wherein the power reception port is coupled to each wire of a pair of data wire pairs at a respective power node, via a respective coil set, wherein the impedance of the first type coil is greater than the impedance of the second type coil when data is being transmitted at a minimum frequency, and wherein the impedance of the second type coil is greater than the impedance of the first type coil when data is being transmitted at a maximum frequency.
