CAT 5
Category 5 cable, commonly known as Cat 5 or Cat-5, is an unshielded twisted pair type cable designed for high signal integrity. Used mostly for communication and networking systems - most commonly known as being rated for its Ethernet capability of 100 Mbit/s. Cat 5 cable typically has three twists per inch of each twisted pair of 24 gauge (AWG) copper wires within the cables.
Cat 5 has also been adapted to transmit a HDMI signal, successfully transmitting HDMI over extremely long cable runs, i.e. 40-50 meters.
