With the popularization and development of the Internet, network cables, as an important medium to connect the network, are becoming more and more diverse. According to different classification standards, network cables can be divided into various types. Below, we will introduce the types of network cables from several aspects, such as the material of the network cable, whether it is shielded or not, the number of cores, and the transmission rate.
1. Classification by material.
1.Pure copper network cable: Pure copper network cable adopts pure copper conductor, which has good conductivity and transmission performance, high stability, and is widely used in low-speed networks, security monitoring and other scenarios.
2.Aluminum wire network cable: Aluminum wire network cable is made of pure aluminum or aluminum alloy material, which is cheaper than pure copper network cable, but the transmission performance and stability are poor, and it is easy to be affected by oxidation and corrosion.
3.Copper-clad steel mesh cable: Copper-clad steel mesh cable is made of copper-core outer steel material, which has good conductivity and transmission performance, and is suitable for general network transmission.
Second, according to the shielding or not.
1.Unshielded Ethernet Cable (UTP): An unshielded Ethernet cable is a network cable without a metal shield, which consists of 8 thin wires inside, and each thin wire has an insulating layer on the outside. The unshielded network cable has a short transmission distance and is suitable for short-distance LAN connections.
2.Shielded network cable (FTP): Shielded network cable refers to a network cable with a metal shielding layer, and its internal structure is the same as that of an unshielded network cable, but the metal shield can effectively reduce electromagnetic interference and radiation, and improve the stability and transmission rate of the network. It is suitable for scenarios such as high-speed network and long-distance transmission.
3.Armoured network cable (ASTP): Armoured network cable refers to the addition of a layer of metal sheath on the basis of shielded network cable, which has stronger anti-interference ability and explosion-proof performance, and is suitable for network cabling in outdoor and high-rise buildings.
3. Classification according to the number of cores.
1.Single-core network cable: A single-core network cable has only one core, which is generally used in scenarios such as low-speed networks and security monitoring.
2.Twisted pair: Twisted pair is made of two copper wires with an insulating protective layer wound with each other, which can effectively reduce electromagnetic interference and signal attenuation. Twisted pair cable is one of the most widely used types of network cables and is suitable for various network connection scenarios.
3.Multi-core network cable: A multi-core network cable is composed of multiple cores, which can provide more transmission channels and faster transmission rates. Multi-core network cables are generally used in scenarios such as high-speed networks and data centers.
Fourth, according to the transmission rate classification.
1.100 Gigabit Ethernet cable: 100 Gigabit Ethernet cable refers to a network cable with a transmission rate of 100Mbps, which is suitable for low network transmission requirements.
2.Gigabit network cable: Gigabit network cable refers to a network cable with a transmission rate of 1Gbps, which is suitable for high-speed network transmission and large-capacity data transmission.
3.10 Gigabit Ethernet cable: 10 Gigabit Ethernet cable refers to a network cable with a transmission rate of 10 Gbps, which is suitable for ultra-high-speed network transmission and high-bandwidth application scenarios.
In addition to the above classifications, it can also be customized according to different application scenarios and special requirements, such as low-smoke halogen-free flame retardant environmental protection network cables, elevator special network cables, etc. Different types of network cables have their own advantages and disadvantages, and the appropriate network cable type should be selected according to the specific situation in actual use to ensure the stability and transmission performance of the network.
