How to crimp a RJ45 cable?
The RJ45 cable is a standard cable which has four twisted pairs of colors. It is easy to crimp a RJ45 cable and make it into a straight cable or cross the cable as required. To make a straight cable, the ends must be crimped in the same way at each end. When making a crossover cable, some wires of certain colors have to be reversed. Learning how to crimp a RJ45 cable and making straight and cross cables prove to be useful as different types of wires of varied lengths are required to build a network.

-------------------------------------------------
What you need?
* A reasonable length FTP cable
* Two RJ45 tips
* A clip crimp

-------------------------------------------------
How to proceed?
Strip the cable to 2 cm at each end and separate the strands. 

They are usually divided into 4 twisted pairs of colors: 

Orange / orange-white 
Green / green-white 
Blue / white and blue 
Brown / brown-white 

-------------------------------------------------
Making a straight cable
To make a straight cable, the tips must be crimped typically the same way at each end by respecting the twisted pair size. 

In general, the code used is: 

1) orange-white 
2) orange 
3) green-white 
4) Blue 
5) blue-white 
6) Green 
7) brown-white 
8) brown 

-------------------------------------------------
Making a crossover cable
For a crossover cable, swap 1 with 3, and 2 with 6, in the list above. This gives: 

1) green-white 
2) green 
3) orange and white 
4) Blue 
5) blue-white 
6) orange 
7) brown-white 
8) brown 

-------------------------------------------------
The standard EIA / TIA 568 (A & B)
Straight cable 

1) white-green / white-green 
2) green / green 
3) white-orange / white-orange 
4) Blue / blue 
5) white-blue / white-blue 
6) Orange / orange 
7) white-brown / white-brown 
8) brown / brown 

-------------------------------------------------
For crossover cable 10/100baseT
1) white-green / white-orange 
2) Green / orange 
3) white-orange / white-green 
4) Blue / blue 
5) white-blue / white-blue 
6) Orange / green 
7) white-brown / white-brown 
8) brown / brown 

-------------------------------------------------
To complete crossover cable or cross gigabit
-------------------------------------------------
On Gbic 1000BaseT eg
1) white-green / white-orange 
2) Green / orange 
3) white-orange / white-green 
4) Blue / white-brown 
5) white-blue / brown 
6) Orange / green 
7) white-brown / blue 
8) Brown / white-blue 

Note: 

Many Gigabits (10/100/1000 multi speed) are auto MDI / MDIX and automatically adapt to the type of cable connected.

TIA/EIA T568A VS. T568B
[Q] What is the difference between the TIA/EIA standards 568-A and 568-B?[A] In order to explain the standard correctly, we must first discuss a little history that is relevant to this standard.In 1985, the Computer Communications Industry Association requested that the Electronic Industries Alliance (EIA) to develop standards for the cabling used in telecommunications applications.The first revision of this standard was released in 1991, but was later updated again in 1995 due to the massive development of networking technology and new faster high-speed ethernet cables and networking components. This was also replaced later with the current TIA/EIA 568-B standard.Although many aspects of networking structure and performance are addressed in these standards, the...
