1. Types and characteristics of network cables
Network cables, also known as network cables or Ethernet cables, are transmission media that connect computers, routers, switches and other network devices. According to different transmission standards and uses, network cables can be divided into many types, such as twisted pair cables, coaxial cables, optical fibers, etc. Among them, twisted pair cables have become the most commonly used type of network cables in homes and offices due to their moderate prices and stable transmission speeds.
According to the transmission speed, twisted pair cables can be divided into various specifications such as Category 5, Category 5e, Category 6, Category 6e, etc. Different specifications of twisted pair cables differ in transmission speed, transmission distance, anti-interference ability, etc. Users can choose the appropriate type according to actual needs.
KeCheng network cable series:
The network cables we produce include HSYV, HSYZ series, mesh cables, Category 5 CAT5, Category 5e CAT5, Category 6 CAT6, Category 6e CAT6, Category 7 CAT7, Category 7e CAT7, and the shielding types are UTP, FTP/STP, and SFTP. The cable category selection should be based on the project's requirements for the transmission frequency and transmission distance of the integrated wiring system, and the cable category (category 5, category 5e, category 6, category 6e, category 7, category 7e copper core twisted pair cable or optical cable) should be selected.
The highest transmission frequency of the cable:
1. The label of the Category 5 cable is "CAT5", with a bandwidth of 100M, suitable for networks below 100M;
2. The label of the Category 5e cable is "CAT5E", with a bandwidth of 155M;
3. The label of the Category 6 cable is "CAT6", with a bandwidth of 250M, which is used to build a Gigabit network and is the trend of future development.
4. The label of Category 6A cable is "CAT6A", with a bandwidth of 500M, which can be used for access to 10G network.
5. The label of Category 7 cable is "CAT7", with a bandwidth of 600M;
6. The label of Category 7 cable is "CAT7e", with a bandwidth of 1000M;
2. Purchase and use of network cables
When purchasing network cables, in addition to paying attention to the type and specifications of the network cables, you also need to pay attention to the following points:
1. Cable quality: High-quality cables can ensure stable signal transmission and reduce attenuation and interference.
2. Cable length selection: Choose the appropriate cable length according to actual needs and scenarios to avoid signal attenuation or inconvenience in connection due to excessive or short cable lengths.
3. Connector quality: The connector is the interface between the network cable and the device, and its quality directly affects the stability and transmission speed of the network. Therefore, it is crucial to choose a connector with a reliable brand and excellent quality.
When using network cables, you also need to pay attention to the following points:
1. Avoid bending: During the transmission process of the network cable, the stability of the signal will be affected by bending. Therefore, during installation and use, you should try to avoid excessive bending of the network cable to avoid affecting the signal quality.
2. Avoid interference: Electromagnetic interference will affect the transmission effect of the network cable. Therefore, when installing the network cable, try to avoid areas with strong electromagnetic interference, such as near electrical equipment such as televisions and computers.
3. Regular inspection: Regularly inspect and maintain the network cable, discover and solve problems in time, which can extend the service life of the network cable and ensure the stability of the network.
3. Application of network cables in daily life
Network cables have penetrated into every aspect of our lives. In the home environment, network cables connect TVs, computers, mobile phones and other devices, allowing us to enjoy high-definition videos, online games and other entertainment experiences. In the office environment, network cables connect computers, printers and other devices, helping us to complete work tasks efficiently. In addition, with the continuous development of technologies such as the Internet of Things and smart homes, network cables are becoming more and more widely used in smart homes, smart cities and other fields.
In general, as the link connecting the digital world, the importance of network cables is self-evident. Understanding the types and characteristics of network cables, the tips for purchasing and using them, and their application scenarios in daily life is of great significance for us to better utilize network resources and improve the quality of life.
