How to distinguish the ethernet cable is poor or good quality ?

Firstly, we need to understand the basic structure of network cables.

Network cables are usually composed of multiple copper wires, which are wrapped in plastic insulation material. There is usually a protective layer outside the network cable to prevent electromagnetic interference. The quality of these constructions directly affects the performance of network cables. For example, if the quality of copper wire is poor, it may lead to loss of signal transmission. If the quality of plastic insulation materials is not good, it may lead to an increase in electromagnetic interference.

So, how to determine the quality of network cables? Here are some key judgment criteria:

Physical inspection: Firstly, you can judge the quality of network cables by observing their appearance. High quality network cables usually have uniform colors and no obvious scratches or dents. In addition, you can also feel the texture of network cables by touching them. High quality network cables usually feel sturdy and are not easily bent.

Performance testing: In addition to physical checks, you can also use performance testing to determine the quality of network cables. You can use a network tester to test the transmission speed and error rate of network cables. High quality network cables typically have higher transmission speeds and lower bit error rates.

Brand and price: When choosing network cables, brand and price are also important considerations. Generally speaking, the quality of network cables from well-known brands is more guaranteed. In addition, the price can also serve as a reference for judging the quality of network cables. Generally speaking, the quality of network cables with higher prices will be better.

Overall, judging the quality of network cables requires comprehensive consideration of multiple factors. By conducting physical inspections, performance testing, and considering brand and price, you can more accurately determine the quality of network cables. I hope this article can help you make better decisions when choosing network cables.
