Fiber optic cable

Optical fiber cables are a new generation of transmission media. Compared with copper media, fiber optic cables have made great progress in terms of reliability and network functions.

The effect of the shielding layer The outer layer of the wire and cable is generally rubber or a rubber composite sheath. The effect of this layer is insulation, and together it has the effect of protecting the cable from damage.

Whether the cable is high-voltage or low-voltage cable, if it is high-voltage, it will also contain fillers such as resin, which has an insulating effect and is an important part of insulation in high-voltage cables. Low pressure does not have this layer. Moreover, there are things like bows wrapped inside, which are used to fix the cores of the cable and fill the gap in the center.
