What types of network cables are there?

Network cable types include twisted pair, coaxial cable, optical cable, network cable interface and wireless network card, etc. Detailed introduction: 1. Twisted pair is the most common type of network cable. It uses twisting and winding to reduce interference between signals. Twisted pair is divided into STP and FTP; 2. Coaxial cable is a special twisted pair. Line, which consists of an outer conductor and an inner conductor, with a hollow center; 3. Optical cable is a cable that uses light to transmit information. It is composed of optical fiber, which is a kind of glass made of special materials. Fiber, the interior is filled with light; 4. Network cable interface, etc.

Network cables are cables that connect network devices. It is one of the infrastructure of the network. With the continuous development of network technology, there are more and more types of network cables. This article will introduce several common types of network cables.

1. Twisted Pair Cable Twisted Pair Cable is the most common type of network cable. It is twisted and wound to reduce interference between signals. There are two types of twisted pair: STP (unshielded twisted pair) and FTP (shielded twisted pair). STP is cheap but has greater signal interference, while FTP is more expensive but can provide better signal quality. The advantages of twisted pair are cheap price, standardized sockets, and easy installation and maintenance.

2. Coaxial Cable Coaxial cable is a special twisted pair. It consists of an outer conductor and an inner conductor, with a hollow center. The advantage of coaxial cable is high signal quality, but due to its special structure, installation and maintenance are relatively complicated. Coaxial cables are widely used in cable television and video conferencing systems.

3. Optical Fiber Cable Optical cable is a cable that uses light to transmit information. It is composed of optical fibers. Optical fiber is a glass fiber made of a special material that is filled with light. The advantages of optical cables are fast transmission speed and high signal quality, but they are expensive and relatively complex to install and maintain.

4. Network Interface Card (NIC) The network cable interface is a socket plugged into the computer motherboard and used to connect network cables. The type of network cable interface is usually used to specify the type of network cable, such as PCI-Express (PCIe) interface, PCI interface, ISA interface, etc. Different types of network cable interfaces have different slots and interface sizes. You need to choose the appropriate network cable interface according to the model and interface type of the network device.

5. Wireless Card A wireless card is an electronic device plugged into a computer and used to connect to the network wirelessly. The type of wireless network card is usually used to specify the type of wireless network, such as 802.11a/b/g/n, etc. Different types of wireless network cards have different frequencies and powers. You need to choose the appropriate wireless network card based on the model of the network device and the type of wireless network card.

In short, there are many types of network cables. When choosing a network cable, you need to choose the appropriate network cable type according to your own needs and the model of the network device. At the same time, in order to ensure the stability and reliability of the network, attention must be paid to the quality of network cables and the installation and maintenance of sockets.
