2. 信号干扰：检查网线周围是否存在电磁干扰源，如无线电设备等。如有干扰源，尽量远离或采取屏蔽措施。 3. 传输速度慢：检查网络设备和终端的传输速度设置是否匹配网线的传输速度要求。如不匹配，调整设置或更换更高规格的网线。 4. 损坏问题：如发现网线表面有破损或断裂现象，应及时更换新的网线。 英文翻译： From Beginner to Expert: A Comprehensive Knowledge of Network Cables I. Overview of Network Cables Network cables, as the foundation of computer networks, play a crucial role in connecting various network devices and terminals, such as computers, routers, switches, etc. They are important channels for data transmission, providing stable signal transmission and high data transmission rates. II. Types of Network Cables Network cables can be divided into multiple types based on different application scenarios and transmission speed requirements. Common types of network cables include twisted-pair cables, coaxial cables, and fiber optic cables. III. Structure and Characteristics of Network Cables Network cables are usually composed of conductors, insulation layers, shielding layers, and external protective layers. The conductor is the medium for transmitting signals, the insulation layer protects the conductor and prevents signal interference, the shielding layer reduces electromagnetic interference, and the external protective layer protects the internal structure. Different types of network cables have different structures and characteristics, but they all have stability and high-speed transmission characteristics. IV. Use and Maintenance of Network Cables 1. Correct installation: Follow the correct steps and methods to ensure that the network cable connection is secure and in good contact. 2. Prevention of damage: Avoid bending, stepping on, or scratching the network cable to prevent damage to its internal structure and ensure smooth signal transmission. 3. Regular inspection: Regularly check the connection status and appearance of the network cable to identify and resolve problems in a timely manner. 4. Cleaning and maintenance: Clean the dust and dirt on the surface of the network cable to keep it clean and tidy. V. How to Choose a Suitable Network Cable? When selecting a suitable network cable, consider the following factors: application scenario, transmission speed requirements, price and cost, brand and quality. Choose a network cable that meets your needs in terms of type, specification, and price while ensuring stability and reliability through a reputable brand and quality products. VI. Common Problems and Troubleshooting for Network Cables During use
