Category 3 cable, commonly known as Cat 3 or station wire, and less commonly known as VG or voice-grade[1] (as, for example, in 100BaseVG), is an unshielded twisted pair (UTP) cable used in telephone wiring. It is part of a family of standards defined jointly by the Electronic Industries Alliance (EIA) and the Telecommunications Industry Association (TIA) and published in TIA/EIA-568-B.[2][3]
Although designed to reliably carry data up to 10 Mbit/s,[4] modern data networks run at much higher speeds, and Cat 5e or better cable is generally used for new installations.[5] Cat 3 cables may have 2, 3, 4, or more pairs.[6][7]
