Ethernet 10/100/1000Base-T Straight Thru
Wiring scheme: EIA/TIA 568B
This cable will work with 10Base-T, 100Base-TX 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 1000BaseT uses all of them, and save yourself some future debugging :)

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.
