Production of twisted pair wires

The procedure is as follows:
Step 1:
The length of the twisted pair Cable required to be cut by mistake at the diagonal port is at least 0.6 meters, and cannot exceed 100 meters. Then, use the twisted pair wires to strip the cables. The outer skin of the twisted pair wires is removed by 2-3 cm. Some twisted pair cable contains a soft nylon rope, If you strip out the twisted pair outer skin, feel exposed part is too short, and is not conducive to the production of RJ-45 connector, can hold the twisted pair outer skin, hold the Nylon Wire and peel it off to the bottom of the outer skin to obtain a longer exposed line. For example)
　
Step 2: deploy the twisted pair cable after wire stripping is completed, as shown in.
　
Step 3:
Next, we need to perform the cabling operation. Place the orange pairs in the exposed twisted pair wires to the front of the wire, and the brown pairs to the front of the wire. The green pairs to the left and the blue pairs to the right, as shown in.
Upper: Orange left: Green lower: Brown right: Blue
Step 4:
Place the green and blue pairs in the middle, while the orange and brown pairs remain unchanged, that is, they are placed in the outer position ,.
Left one: Orange left two: Green left three: Blue left four: Brown
Step 5:
Be careful to strip each pair of cables, because we follow the EIA/TIA 568B standard to create connectors, so there is a certain order of colors for the line, as shown in the right figure ).
Note that the Green Line should span the blue line. The easiest thing to make mistakes here is to put the white green line and the green line together, which will cause crosstalk and reduce transmission efficiency.
　
From the left: White orange/white green/blue/white blue/green/White brown/Brown. The common mistake is to place the green line at the position of 4th feet, as shown in ).
　
It is correct to place the Green Line on the 6th foot, because in the 100BaseT network, the 3rd and 6th feet are the same, so the same line must be used.
Cut the exposed twisted pair wires with scissors or diagonal pliers with a length of about 14mm. The reason for leaving this length is to comply with EIA/TIA standards, you can refer to the introduction to standards for making RJ-45 connectors and twisted pair wires. Finally, put each wire of the twisted pair into the pin of the RJ-45 connector in sequence, the first pin should be placed in the white orange line, the rest and so on (such)
　
Step 7:
Determine the twisted pair of each line has been correctly placed after, you can use RJ-45 crimping clamp crimping RJ-45 joints, such as the market there is a kind of RJ-45 joint protective sleeve, can prevent the joints in the pull caused by poor contact. When using this protective cover, you need to put this rubber sleeve on the twisted pair cable before crimping the RJ-45 Connector

Step 8:
Create a RJ-45 connector for the other end. Because if adsl modem is directly connected to the general 10g interface of the hub rather than the UP-LINK port ),
To use crossover lines, the wiring order of the RJ-45 connector at the other end needs to change. That is to say, the line of the original 1st feet is adjusted against the line of the current 3rd feet, and the line of the original 2nd and 6th feet is adjusted. The specific order is: white green/White orange/blue/white blue/orange/White brown/Brown, in accordance with this order and then press the RJ-45 crimping clamp RJ-45 joint, the color sequence of the RJ-45 connectors at both ends of the completed connection line is not the same. The following lists the comparison of the two color order:
End: White orange/white green/blue/white blue/green/White brown/brown
Other end: white green/White orange/blue/white blue/orange/White brown/brown
The direct connection network cable is used for the direct connection between the adsl modem and the computer Nic, and the direct connection is also suitable for the connection between the adsl modem and the UP-LINK port of the hub. The production method is the same as above, only the white orange, orange, white green, and green lines are not crossed.
