What is CAT5 cable?
Category 5 cable, commonly known as CAT5, is an unshielded twisted-pair type cable designed for high signal integrity. The actual standard defines specific electrical properties of the wire, but it is most commonly known as being rated for its Ethernet capability of 100 Mbit/s. Its specific standard designation is EIA/TIA-568. CAT5 cable typically has three twists per inch of each twisted pair of 24 gauge copper wires within the cable.
