The network cable has greatly improved our quality of life and work efficiency. It is mainly used to connect to the LAN. The common network cables in the LAN are mainly twisted pair, coaxial cable, and optical cable.
1. Twisted pair can be divided into shielded twisted pair (STP=SHIELDED) and unshielded twisted pair (UTP=UNSHIELDED). Commonly used twisted pairs are Category 5 and Category 5, Category 6 and Category 6 lines, as well as the latest Category 7 and Category 8 lines.
2. A coaxial cable is a cable that wraps a central copper conductor with a layer of insulated wire.
3. The fiber optic cable is composed of a number of thin fiberglass fiber-reinforced insulating sleeves.
