**Network Cable Selection and Use: Stabilizing Network Performance** With the continuous development of network technology, the internet has become an integral part of people's daily lives. In constructing a stable and efficient computer network system, the selection and use of network cables are particularly important. This article will explore how to choose suitable network cables and how to properly use them to ensure more stable network performance. **I. Network Cable Selection** 1. Type Selection Network cables are mainly divided into different types such as Category 5, Category 5e, Category 6, and Category 7. Category 5 cables are mainly used for networks under 100Mbps, while Category 5e can meet the transmission requirements of Gigabit Ethernet. In current home and office environments, Category 6 and above cables are more preferred, as they can meet the needs of high-speed networks, ensuring network stability and speed. 2. Quality Selection When purchasing network cables, in addition to paying attention to the type of cable, its quality should also be considered. High-quality cables have excellent electrical and physical properties, ensuring stable signal transmission and long-distance transmission. When purchasing, examine the labeling, outer skin process, and the purity of the copper core inside. Generally, the thicker the copper core and the smaller the resistance, the better the transmission effect of the wire. **II. Network Cable Usage** 1. Correct Connection Method When connecting network cables, follow the correct connection method. Generally, use standard RJ45 crystal heads for connection and ensure proper wiring sequence. Incorrect wiring sequence or poor quality crystal heads may lead to network instability or inability to connect. 2. Avoid Excessive Bending and Pulling When using network cables, avoid excessive bending and pulling. Excessive bending and pulling may cause internal wires to break or damage the insulation layer, affecting signal transmission. Therefore, ensure sufficient slack in the cable during installation and wiring to avoid excessive pulling. 3. Regular Check and Maintenance To maintain network stability, regular checks and maintenance of network cables should be performed. Regularly check if the connections are loose or damaged, and promptly replace or repair problematic cables. Additionally, for cables that have not been used for a long time, regular maintenance and care should be performed to ensure their performance is good. **III. Conclusion** Choosing the right network cable and using it correctly are crucial
