The main difference between four-core network cable and eight-core network cable
The network cable is one of the mediums used to transmit signals in the network. At present, the commonly used network cables are 8-core network cables. Some ordinary projects will use 4-core network cables. Under the 100M network, the network cable relies on the internal 4 main lines to transmit the network. , In a sense, the 8-core network cable and the 4-core network cable are no different in the transmission network process. However, in terms of transmission effect and stability, the 4-core network cable is obviously not as good as the 8-core network cable.
Four-core network cable
It refers to a network cable with only 4 cores inside, and the general core colors are orange-white, orange, green-white, and green. There are not many specifications of four-core network cables, which are generally divided into indoor copper-clad aluminum/oxygen-free copper 05 network cables and outdoor copper-clad aluminum/oxygen-free copper 05 network cables. The production process of the four-core network cable is relatively simple, and in an ordinary network environment, the normal network transmission can be ensured, and the cost can be reduced.
The 4-core network cable can be used as network cable and telephone line. It is generally used as the main line for broadband rental. Because many of the network requirements of rental houses are temporary and one-time, the requirements for the network are not very high and the cost is higher than using 8 The core network cable should be low.
If you make a four-core network cable connector yourself, you can use a network cable pliers to press the crystal head. The network crystal head usually uses a super five-type crystal head. According to the T568B wire core, you can connect 4 wire cores to the position of the crystal head 18.104.22.168. (Crystal head up from left to right: 1. orange and white, 2. orange, 3 green and white, 6 green)
Eight-core network cable
It refers to a network cable with 8 cores inside, and the core colors are orange-white, orange, green-white, green, blue, blue-white, brown, brown-white. There are many specifications of the eight-core network cable, which are divided into five types of network cables and six types of network cables.
Super five network cables are divided into indoor network cables and outdoor network cables (conductor materials are: iron-aluminum, copper-clad aluminum, high-conductivity aluminum, copper-clad silver, full copper, oxygen-free copper, conductor size: 0.45-0.51mm), the same for six types of network cables It is divided into indoor network cable and outdoor network cable (conductor material: copper-clad silver, full copper, oxygen-free copper, conductor size: 0.52-0.58mm).
Under the 100M network, the 8-core network cable can rely on 4 cores for transmission. Under the POE power supply and Gigabit network, 8-core network must be used to transmit the network.
Connecting the crystal head According to the T568B wire core, 8 wire cores can be connected to the crystal head, the crystal head is up from left to right: 1. orange white, 2. orange, 3 green and white, 4. blue 5 blue and white. 6 green 7 .Brown White 8 Brown.
The 4-core network cable sometimes has the phenomenon of unstable transmission, which is not suitable for large-scale networks. .The transmission distance of the network cable and the wiring environment also have a certain relationship. The 22.214.171.124 line in the 8-core network cable plays a role in reducing interference, so that the transmission signal will not have too much loss, while the 4-core network cable does not have much in this regard. The performance of the 8-core network cable is good. In actual use, the 4-core network cable is best kept in the transmission distance of about 85 meters.
