Why is the network cable broken back and forth, and the network cable is broken in the middle

The first method: because the color of the 8 wires of the network cable is different, first peel off the rubber skin of the network cable at the broken place, then peel off the skin of the 8 wires in turn, and then screw the copper wire of the corresponding color together, such as green butt green, green and white butt greenish-white. After each wire is connected, it is wrapped with rubber tape.

The second method: you can buy a network cable connector from the place where the network cable is sold, and then check whether the crystal headers at both ends of this network cable are 568A line sequence or 568B line sequence.

568a line sequence: from left to right: green-white, green, orange-white, blue, blue-white, orange, brown-white, brown-white.

568b line order: from left to right: orange-white, orange, green-white, blue, blue-white, green, brown-white, brown-white.

1) If both ends of the network cable are 568A line sequences, use 568A line sequences to re-make the crystal heads at both ends of the broken cable, and then insert the docking through the network cable.

2) If both ends of the network cable are 568b line sequences, use the 568b line sequence to re-make the crystal heads at both ends of the broken cable, and then insert the docking through the network cable.

3) If one end is 568a line sequence, and one end is 568b line sequence, then one end of the 568a line sequence, the broken end is the crystal head of the 568a line sequence, and the broken end is the crystal head of the 568b line sequence, and then the docking can be inserted into the connector through the network cable.

Note: The first method is not as effective as the second method, and sometimes it will cause interference and cause packet loss on the network. It is recommended to use the second method to connect the disconnected network cable.

There are four main wiring methods after the network cable is broken, as follows: 1. Winding method Winding method is the most simple and convenient method, only need to strip the 8 cores in the network cable respectively, each core wire is screwed firmly, two network cables of the same line sequence are wound together with each other, and wound by insulating tape. However, it should be noted that the network cable adopts the winding method, which will cause interference and loss of the signal, so it is only suitable for emergency or temporary detection, and it is not recommended to use it for a long time.

2. The wiring sub-method is a more professional network connection method, which uses the wiring to connect the 8-core network cables. You only need to plug the adapter into both ends of the network cable and fix it, the 100 Gigabit network can only be connected to the four-core copper wire, and the Gigabit network needs 8 network cables to be connected. Therefore, at least 8 terminals should be prepared for the wiring method.

When wiring, you need to peel off both ends of the network cable to expose 3-5 cm. When connecting, it is necessary to pay attention to the color and connect it one by one.

Summary. Dear, the reasons why you can still use it if the network cable is broken are as follows:

There are two standards for network cables:

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.

The above two types of cross-wires and straight-connected wires use these four cores (white-green, green, white-orange, orange two pairs of stranded wires). If one of these four cores is broken, the network cable cannot be used normally; If the four-core spare wire core is interrupted, it will not affect the use (take the ordinary 100m wire as an example).

Why is it still usable if the network cable is broken?

Dear, the reason why the network cable can still be used is as follows: There are two standards for the network cable: 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 The above two kinds of cross-wires or straight-connected wires are used in these four cores (white-green, green, white-orange, orange, two pairs of stranded wires). If one of these four cores is broken, the network cable cannot be used normally; If the four-core spare wire core is interrupted, it will not affect the use (take the ordinary 100m wire as an example).

Hope it helps!

There may be the following reasons why the new network cable breaks the stupid chain and holds it:

1.There is a high temperature, humidity or pH in the use environment, which causes the surface of the network cable to be corroded and damaged.

2.During the bending or bending process of the network cable, the pressure is too high for a long time, resulting in the breakage of the metal core of the network cable. (The strength of the relay metal core can be improved by selecting high-quality network cable materials and structural design with uniform density distribution).

3.Considering the quality of the network cable, sometimes there are human factors, such as tearing, pulling, cutting, etc.

4.The connection between the network cable interface and the device is slightly scratched or the connection is not tight (plug and play).

5.Excessive switching for a long time, such as directly connecting the network cable to the computer port or the switch port.

6.Factors such as rat gnawing and pet frolicking create impressions.

It should be noted that once the network cable is broken, the imitation of ordinary home network services will also be hit, and it is more serious in the internal network of the enterprise. Able to take certain measures to repair or replace relay cables, so as to avoid losses caused by open circuits.
