How far is the transmission distance of the eight types of network cables?

　　The tranSMission distance of Category 8 cable (Cat8) is an important parameter of its performance. The following is a detailed description of the transmission distance of Category 8 cable:

　　Standard transmission distance

　　As the latest generation of dual-shielded (SFTP) network cables, Category 8 network cables support up to 40Gbps transmission speeds and bandwidth frequencies up to 2000MHz. However, in order to ensure the best performance, its transmission distance is limited to 30 meters. This means that within 30 meters of transmission distance, Category 8 network cables can provide stable and high-speed network connections.

　　Second, the factors affecting the transmission distance

　　Network cable quality: The material of the network cable, the wire gauge (that is, the thickness of the wire core), and the shielding effect all affect its transmission distance. High-quality network cables usually have better transmission performance and longer transmission distance. For example, some eight types of network cables use refined copper cores with thick wire diameter, small resistance, and high conductivity, thus improving transmission distance and signal stability.

　　Environmental factors: Environmental factors such as temperature and humidity may also affect the transmission distance of the network cable. For example, excessive humidity may cause electrolysis inside the network cable, corroding the copper core part, thus affecting the transmission effect. Therefore, try to keep the environment dry when wiring.

　　Electromagnetic interference: Electromagnetic interference (EMI) can cause noise in the network cable and affect the signal quality. Therefore, when wiring, it should be avoided to lay in parallel with interference sources such as high-power power lines to reduce the impact of electromagnetic interference on the transmission distance of the network cable.

　　III. Application scenarios

　　Due to the relatively short transmission distance of the Category 8 network cable, it is usually used to connect servers, switches, patch panels, and other equipment in short-distance data centers. In these scenarios, the requirements for network performance are extremely high, and high-speed, low-latency, and high-bandwidth network connections are required. The Category 8 network cable can meet these requirements and provide stable and reliable network transmission.

　　In summary, the standard transmission distance of the eight types of network cables is within 30 meters. In practical applications, factors such as cable quality, environmental factors, and electromagnetic interference may all affect the transmission distance. Therefore, when selecting and using the eight types of network cables, these factors need to be comprehensively considered to ensure the stability and reliability of the network connection.
