With the continuous development of technology, the types of network cables have also become increasingly diverse. Below, we will provide a detailed explanation of the types of network cables and their respective characteristics. Types of Network Cables: 1. Coaxial Cable: Coaxial cables are the earliest widely used network cable types. They are composed of an inner conductor, insulating material, a mesh shielding layer, and an outer insulating layer. Due to their structural characteristics, coaxial cables have good anti-interference ability and high data transmission rates. 2. Twisted Pair: Twisted pair cables consist of two copper wires with insulating layers, twisted according to certain rules. Depending on the twisting density and material of the wire pairs, there are various types of twisted pair cables, such as CAT5, CAT5e, CAT6, and CAT7. Twisted pair cables are widely used due to their low price and convenient wiring. 3. Fiber Optic Cable: Fiber optic cable is a network cable that uses optical signals as the transmission medium. It is composed of optical fibers, claddings, and protective layers, and has the advantages of fast transmission speed, long transmission distance, and resistance to electromagnetic interference. Fiber optic cables are usually used for high-speed and long-distance network connections. Characteristics of Various Network Cables: 1. Coaxial Cable: Advantages include strong anti-interference ability, relatively long transmission distance, and suitability for early network applications. Disadvantages include relatively low transmission speed and complex wiring, gradually being replaced by twisted pair and fiber optic cables. 2. Twisted Pair: Advantages include low price, convenient wiring, high transmission rate, and wide application in local area networks and home networks. Disadvantages include limited transmission distance, and the need for repeaters or other devices for signal amplification in long-distance transmissions. 3. Fiber Optic Cable: Advantages include fast transmission speed, long transmission distance, strong resistance to electromagnetic interference, and suitability for high-speed and long-distance network connections. Disadvantages include a relatively high price and the need for professional equipment and skills for wiring. In conclusion, different types of network cables have their own characteristics and applicable
