The materials of network cable core are as follows:

1. Pure copper wire. This kind of wire is the best wire. Under the same conditions, the resistance of copper is small, so it can be made of high-quality wire. It is also suitable for POE power supply. Small resistance can avoid the loss of electricity in the transmission process

2. Aluminum wire. This kind of network cable is inferior in quality to copper wire, and can be selected for the line of terminal switch in household or small office. This type of wire is only suitable for short distance POE power supply because the resistance is larger than copper wire

3. Copper clad iron wire. The conductivity of the iron wire is improved to a certain extent, but this kind of wire is not suitable for POE power supply because of its high resistance

4. Iron core wire. This type of network cable has a large resistance, and is only suitable for short distance transmission and low network speed requirements. This type of wire is not suitable for POE power supply, also because of high resistance

5. Mixed wire. It is only suitable for short distance use and can be used for POE power supply, but the crystal head must be made in strict accordance with the wire sequence, otherwise the copper wire cannot be used for power supply

Network cable is necessary to connect the LAN. The common network cables in LAN mainly include twisted pair, coaxial cable and optical cable. Twisted pair is a data transmission line composed of many pairs. Its characteristic is that it is cheap, so it is widely used, such as our common telephone lines

Copper wire is a very good material for wire mesh manufacturing, and the wire diameter size of copper wire also determines the quality of wire mesh. This paper introduces the wire diameter detection of copper wire

The quality of copper core is often one of the key points that network cable customers pay attention to. In order to achieve more accurate detection of the wire diameter quality of copper core, it is necessary to conduct continuous online detection, so as to ensure the wire diameter quality of each inch of network cable copper core
