Cat Cable

LAN (local area network) cable or Ethernet cable includes cat5e, cat6, and cat7 twisted pair cable. A LAN is a network that connects devices such as computers or printers to each other and then will connect out to the internet or phone lines via a WAN (wide area network).
The cable that connects all of the devices in a LAN today is Ethernet cable. This cable comes in cat5e, cat6, and cat7; each is progressively faster and a cleaner connection than its predecessor but cat6 Ethernet cable is the most common. The Ethernet cable wiring consists of 4 pairs: whiteorange and orange, whitegreen and green, whiteblue and blue, and whitebrown and brown. Each of these pairs of wire is twisted onto each other and the four pairs are also twisted. The tighter the twist on the cable the cleaner the signal is as this reduces crosstalk or EMI (electro-magnetic-interference).
