How To Make A Network Cable RJ45

Network cable crystal head connection


There are two methods for connecting the crystal head of the cable, one is the direct connection and interconnection method, and the other is the cross-connection method. The crossover approach is: One end adopts the 568A standard and one adopts the 568B standard. The practice of parallel (through) lines is: both ends are 568A standard or 568B standard.RJ45 connctor

 

 

Operation method
There are two ways to use a network cable. One is a crossover cable, and the other is a parallel (straight through) cable.
The crossover approach is: One end adopts the 568A standard and one adopts the 568B standard.
The parallel (straight-through) line approach is: Both ends are the same as the 568A standard or the 568B standard (the general approach is the 568B parallel (straight-through) line)
568A Standard: White Green, Green, White Orange, Blue, White Blue, Orange, White Brown, Brown
568B Standard: White Orange, Orange, White Green, Blue, White Blue, Green, White Brown, Brown

 

Steps/methods

First come to know about the network cable module, this is the module installed behind the home network cable socket, on the left and right sides, the above A, B shows two different threading methods, you can choose one.
1-3, 2-6 cross connection. Although twisted pairs have 4 pairs of 8 cores, actually only 4 of them are used in the network, namely, the 1st, 2nd and 3rd and 6th feet of the crystal head. They respectively receive and send. The role of the signal. The core arrangement of this crossover cable is:
The first leg of one end of the network cable is connected to the third leg of the other end, and the second leg of one end of the network cable is connected to the sixth leg of the other end, and the other legs can correspond one by one. This sort of arrangement is often referred to as a "crossover line. For example, the cores from left to right at one end of the line are: white green, green, white orange, blue, white-blue, orange, white-brown, brown The order of the cores at the other end from left to right should be: white orange, orange, white green, blue, white blue, green, white brown, and brown.
100M connection method. This is one of the most commonly used rules for making network cables. The so-called 100M connection means that it can meet the communication speed of 100M bandwidth. Although its connection method is also a one-to-one correspondence, the color of each foot is fixed. specifically is:
Foot 1 - Orange, 2nd - Orange, 3rd - Green, 4th - Blue, 5th - Blue, 6th - Green, 7th - - Brown, 8th - brown, from which it can be seen that the 4 pairs of cores of the network cable are not all arranged adjacent to each other, the 1st, 3rd, 5th, and 7th feet include 2 pairs of cores. , but the order has been confused.
This wiring method is also applied to the connection between the hub (switch) and the workstation computer, that is, the scope of the "direct connection".
After starting to play the line, first of all, first peel off the skin of the cable, this time can be stripped to a long point, easy to play back line. Four twisted pairs are exposed:
Divide the line into left and right two groups. Put the line of the corresponding color in the corresponding position of the module according to A or B: Before we play the line, let's get to know the threading tool: this is the head of the threading tool, the metal side (The right side of the image below) is a head similar to a scissors, and you can trim off excess threads.
Then start the line, press the module and the wire with the tool, press down forcefully, insert the wire inside the module, and cut off the excess thread.
Play other lines in the same way

 

 

Note:

If the two parties to the connection are in an unequal position, use a parallel (straight through) line, such as a computer connected to a router or switch
If the two connected devices are peers, use a crossover line, such as a computer connected to the computer
It is possible to connect all the same, because only 1.2.3.6 other cables are generally available if they are not connected.
