1. A power-over-Ethernet (POE) cable for connecting a power sourcing equipment and a power device and supplying power while establishing data communication, the PoE cable comprising:
a plurality of pair units each formed by twisting a pair of conducting wires to have twist pair pitches, the pair of conducting wires including a conductor with a diameter of 0.59 to 0.61 millimeters (mm) and an insulator surrounding the conductor; and
an outer jacket surrounding the plurality of pair units,
wherein the plurality of pair units are twisted together to have a collective pitch,
among the twist pair pitches of the plurality of pair units, a minimum twist pair pitch is in a range of 12 to 15 mm and a maximum twist pair pitch is twice or more the minimum twist pair pitch, and
the PoE cable has an outer diameter of 6.2 mm or less,
wherein, when the PoE cable is 200 meters (m) long, the pair of conducting wires has a conductor resistance of 12.5 Ohms (Ω) or less, and power consumption of the PoE cable is 4.5 Watts (W) or less during transmission of power.
