The characteristics of computer cables mainly include the following aspects:

1. Superior shielding performance: Computer cables adopt a multi-layer shielding structure, including a shielding layer composed of metal materials such as copper wire or aluminum foil. This shielding layer can effectively resist external electromagnetic interference (EMI) and radio frequency interference (RFI), prevent signal leakage and attenuation, and ensure the stability and reliability of data transmission.
2. High transmission rate: Computer cables have a high transmission rate and support high-speed data transmission. For example, Ethernet cables can support transmission speeds of up to gigabits per second (Gbps) or even higher. This high-speed transmission capability enables computer cables to meet various applications with large amounts of data and high bandwidth.
3. Stable electrical performance: High quality insulation materials are used between the core and shielding layer of computer cables to ensure the stability of electrical performance. In addition, the voltage level, resistance, capacitance and other parameters of the cable are strictly controlled and tested to ensure that there will be no electrical faults or performance degradation during use.
4. High durability and reliability: The insulation layer, shielding layer, and protective layer of computer cables are made of high-quality materials, which have excellent wear resistance, high temperature resistance, corrosion resistance, and other characteristics. This enables computer cables to maintain stable performance and a longer lifespan during long-term use.
5. Widely used: Due to its various characteristics, computer cables are widely used for signal and data transmission between various computer equipment and automation instruments. For example, the connection between computers and devices such as printers, scanners, disk drives, as well as signal transmission in industrial automation control systems.

In summary, computer cables have become an indispensable and important component in modern electronic equipment and data communication systems due to their superior shielding performance, high-speed transmission rate, stable electrical performance, high durability and reliability, and wide application range.
