What are the access methods of the network cable?

　　The access methods of network cables can be mainly divided into the following categories:

　　First, the basic access method

　　Winding method:

　　Peel the 8-core wires in the mesh wire separately, and tighten each core wire firmly.

　　Two network wires of the same thread sequence are wound together and fixed by insulating tape.

　　This method is simple and primitive, but the signal loss and interference will be relatively large, and it is only suitable for emergency or temporary detection, not for long-term use.

　　Wiring method:

　　Use a connector (adapter) to connect the 8-core network cable.

　　Peel off both ends of the network cable to expose 3-5 cm, insert the cores of the same color into the adapter and fix them.

　　This method is often used in scenarios where the network cable is damaged or requires local extension. It is easy to implement, but it may affect the stability and propagation speed of the network signal.

　　Connector method:

　　Use a network cable connector (butt) to connect the two network cables.

　　Make a crystal head at one end of the network cable, insert it into the connector, and connect the other end to another network cable with the crystal head.

　　This method is simple, practical, and inexpensive, making it a common solution when the network cable is not long enough or multiple network devices need to be connected.

　　Welding method:

　　Solder the 8-core wires in the mesh wire together, and the colors should match.

　　This method requires high technical requirements and professional welding tools. It is not recommended for non-professionals to operate it.

　　Second, the line sequence access method (making network cable)

　　Cross wire connection:

　　The crystal heads at both ends of the network cable are wired to different standards, namely, one end uses the 568A standard and the other end uses the 568B standard.

　　Line sequence:

　　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.

　　This method is usually used to connect devices of the same type, such as two computers directly connected.

　　Parallel (through) line connection method:

　　The crystal heads at both ends of the network cable are wired to the same standard, that is, both ends use the 568A standard or both ends use the 568B standard.

　　Since the 568B standard is more commonly used, parallel lines are mostly wired using the 568B standard.

　　The line sequence is the same as the 568B standard.

　　This method is often used to connect different types of devices, such as a PC network interface card to a normal port of a HUB (hub).

　　III. Access steps

　　Whether it is a crossed line or a parallel line, the wiring steps are roughly the same, mainly including the following steps:

　　Stripping: Use the stripping knife of stripping pliers or crimping pliers to remove a length (usually about 10 cm) of the skin of the network cable, taking care not to hurt the metal wiring.

　　Split wires: Arrange the stripped mesh wires in standard line sequence, and then insert each wire into the metal card slot of the crystal head. Be careful to ensure that each wire is inserted to the bottom and cannot be bent.

　　Crimping wire: Put the crystal head of the plugged wire into the crimping notch of the mesh wire pliers, and then press down the handle of the mesh wire pliers with force, so that the pins of the crystal head can be inserted into the core wire of the mesh wire, making good contact with it.

　　Test: After the wiring is completed, the network cable tester can be used to test the connectivity of the network cable to ensure the accuracy of the wiring.

　　In summary, there are various access methods for network cables, and the choice of which method depends on the specific application scenarios and needs. In practice, it is necessary to ensure that the wiring sequence of each cable is correct to avoid unstable network performance or inability to connect.
