Category 2 cable
Category 2 cable, also known as Cat 2, or Level 2, is a grade of unshielded twisted pair cabling designed for telephone and data communications. The maximum frequency suitable for transmission over Cat 2 cable is 4 MHz, and the maximum bandwidth is 4Mbit/s.[1] Cat 2 cable contains 4 pair of wires, or eight wires total.[2]
Though not an official category standard established by TIA/EIA, Category 2 has become the de facto name given to Level 2 cables originally defined by Anixter International, the distributor. Official TIA/EIA-568 standards have only been established for cables of Category 3 ratings or above.
Anixter Level 2 cable was frequently used on ARCnet and 4 Mbit/s token ring networks, it is also used in telephone networks but it is no longer commonly used.
