Because the reliability and requirements of the cables used in communication are completely different from those of ordinary types, there may also be some differences. Therefore, we must check whether the variables are sufficient and whether the solderability of the copper mesh is good, in order to facilitate subsequent use. It is recommended to check the cross-sectional area when purchasing communication cables. If it is copper clad aluminum, it can be seen that the internal color and external color are different. Peeling off the outer skin can directly reveal the weaving angle. And if it's pure copper
