It is primarily used for voice networks and runs from closet to closet or even from patch panel to patch panel. Also used with
Amphenol style connector for cross connection of voice networks. It is heavier then regular Cat3 cable for it has 25 pairs as
opposed to only 4 pair UTP (UTP Unshielded Twisted Pair). Cat5e and above is used in data networks today.
