1. 网线的选择应根据实际需求和场景进行，不要盲目追求高速或低价。应选择符合规范的产品并保证其质量可靠。 2. 在制作和布线过程中要严格按照操作规程进行，避免操作不当造成网线的损坏或性能下降。 3. 在使用过程中要定期检查和维护网线，确保其正常工作并延长使用寿命。 **Network Cable Knowledge Comprehensive Analysis: An Essential Element of Network Connection** I. Introduction to Network Cables Network cables, also known as network lines or Ethernet cables, are one of the indispensable elements of modern network connections. By connecting network devices (such as computers, routers, switches, etc.), they enable high-speed data transmission and resource sharing. II. Types and Characteristics of Network Cables 1. Types: Network cables are mainly divided into Category 5 (CAT5), Category 6 (CAT6), and Category 6A (CAT6A) cables based on their transmission speed and distance. 2. Characteristics: - CAT5 cable: Mainly used for ordinary LAN connections, with slower transmission speed and shorter transmission distance. - CAT6 and CAT6A cables: Suitable for high-speed network connections such as Gigabit or 10 Gigabit networks, with faster transmission speed and longer transmission distance. III. Structure and Manufacture of Network Cables 1. Structure: A network cable mainly consists of a central conductor and eight core wires wrapped in insulating material. Each core wire is wrapped in color-coded insulation material, and the outside of the cable is covered with a protective sheath.

2. Manufacture: To manufacture a network cable, the number and length of core wires required are determined based on the connection needs. Then cutting, stripping, and pairing are performed, followed by connecting both ends in accordance with the corresponding T568A or T568B wiring order using a network module (RJ45 module).

IV. Usage and Maintenance of Network Cables 1. Usage: Network cables are primarily used to connect different network devices to form a complete network structure. Different cabling methods such as patch cords and crossovers are employed to meet different network requirements. 2. Maintenance: Regularly inspect the connection status and transmission performance of network cables during use to ensure their proper functioning. During cabling, avoid excessive bending or pulling on the cables to prevent affecting their transmission performance. Damaged cables should be replaced promptly to ensure network stability and security. V. Precautions 1. Select network cables based on actual needs and scenarios instead of blindly pursuing high speed or low prices. Choose products that meet standards and ensure their quality reliability. 2. Strictly follow operation procedures during manufacturing and cabling to avoid improper operations that may cause damage or performance degradation of the cables. 3. Regularly inspect and maintain network
