What's the difference between four-core and eight-core cables?

A network cable is one of the media in which signals are transmitted over a network.At present, the commonly used network cable is 8-core network cable, and some ordinary projects will use 4-core network cable.Under a 100-megabit network, the cable relies on four main lines inside the network to carry the network.In a sense, there is no difference between the 8-core cable and the 4-core cable in the process of transmitting the network.However, in terms of transmission effect and stability, 4-core network cable is obviously not as good as 8-core network cable.

So, in computer network engineering, what is the difference between four - core network cable and eight - core network cable?

1, 4 core network cable:

A four-core cable refers to a network cable with only four inner cores. Generally, the core colors are orange, orange, green, and green.The specifications of four-core network cables are not many, usually 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 four-core network cable is relatively simple, in the general network environment, can ensure the normal network transmission, reduce the cost.

Four-core network cables can be used as network cables, telephone lines, generally used to do broadband rental main line, because the rental housing network demand is mostly temporary, more one-time, the requirements for the network is not high, and the cost is lower than the use of eight-core network cables.

If you make a four-core network cable connector, press the rj45 connector with the network cable pliers.Network rj45 usually uses more than five types of rj45.According to the T568B cores, you can connect the four cores to 1.2.3.6 of the RJ45 connector.(Crystal head up from left to right: 1. Orange and white, 2. Orange, 3 green and white, 6 green).

2, eight core network cable:

An eight-core network cable is a network cable with eight inner cores. The core colors are orange, orange, green, green, blue, blue, white, brown, and white.Eight core network cable specifications, divided into more than five categories and more than six categories.Super 5 types of network cables are divided into indoor and outdoor network cables (conductor materials: iron-aluminum, copture-clad aluminum, high-conducting

aluminum, copture-clad silver, full copper, oxygen-free copper, conductor size :0.45-0.51mm), and 6 types of network cables are also divided into indoor and outdoor network cables (conductor materials: copture-clad silver, full copper, oxygen-free copper, conductor size :0.52-0.58mm).On a 100m network, an 8-core cable can be transmitted through four cores. On a POE power supply network and a GIGABit network, an 8-core transmission network must be used.

Connect eight wire cores to the RJ45 connector based on the T568B cores. The RJ45 connector is from left to right: 1.Orange and white, 2. Orange, 3 green and white, 4. Blue 5 blue and white, 6 green 7.

Four-core network cables are sometimes unstable and are not suitable for large networks.The transmission distance of the network cable is also related to the wiring environment.

The 4.5.7.8 of the eight-core network cable plays a role in reducing interference, so that the transmitted signal will not be lost too much. In this respect, the performance of the four-core network cable is not as good as that of the eight-core network cable.In practical use, the 4-core network cable is best maintained at about 85 meters transmission distance.

Lan Cable Features:                                                                                                                

A). 4 pairs or bulk pairs Cat.6 cable / Cat.6A / 24AWG bare copper to be the center conduction, PE to be the dielectric and fireproof material

to be the jacket.

B). Cable is blue and conforms to the standards like ISO/IEC, TIA/EIA and EN.

C). All the electrical characteristics even exceed the latest Cat.6 ISO/IEC standards. The ‘+’ type inner frame in the center ensures NEXT

capacity and reasonable minimum bend radius.

D). LSZH: means ‘Low Smoke Zero Halogen’, which is the symbol of environmental protection.
