There is more than one stringer in these cables. The conductor used in this type is made of copper metal and the insulation used in them is usually made of PVC. These cables do not break easily, they can be bent and shaped to any shape. These cables are very soft, which is why they avoid using them over long distances.
Coaxial cable is one of the most important cables used in network projects for data and signal transmission. These cables are also called coaxial cables. In these cables, the internal media (conductor) is covered with flexible insulation, which is usually made of polymer. One of the most important features of these cables is the absence of noise along the transmission line in the receiving conditions, but if these cables have a transmitter role, you will not see any radiation along the cable; This means that the transmitted wave along the path will be fully protected.
