Ethernet 10/100/1000Base-T Straight Thru

Wiring scheme: EIA/TIA 568B

This cable will work with 10Base-T, 100Base-TX, 100VG-Anylan and 1000Base-T and is used to connect a network interface card to a hub or network outlet. These cables are sometimes called "whips".

Note: While 10BaseT and 100Base-TX only uses two pairs, please do connect all pairs since 100VG-Anylan and 1000BaseT uses all of them, and save yourself some future debugging :)

Name Pin Cable Color Pin Name
TX+ 1 White/Orange 1 TX+
TX- 2 Orange 2 TX-
RX+ 3 White/Green 3 RX+
  4 Blue 4  
  5 White/Blue 5  
RX- 6 Green 6 RX-
  7 White/Brown 7  
  8 Brown 8  

Note: It's important that each pair is kept as a pair. TX+ & TX- must be in the pair, and RX+ & RX- must together in another pair. (Just as the table above shows).

Just for your information, this is how the pairs are named:

Pair Pins Common color
1 4 & 5 Blue
2 1 & 2 Orange
3 3 & 6 Green
4 7 & 8 Brown

The + side of each pair is called the "tip" and the - side is called the "ring", a reference to old telephone connectors.
