2. Coaxial Cable Coaxial cable is a network cable with good shielding effect, mainly used for TV signal transmission and broadband network connections. Its structure includes a center conductor, insulating layer, shielding layer, and outer sheath. Coaxial cables have a higher transmission rate but are relatively expensive. 3. Fiber Optic Cable Fiber optic cable is a network cable that uses optical signals as the transmission medium, with advantages such as long transmission distance, high transmission speed, and strong anti-interference ability. Fiber optic cables are composed of optical fiber cores, claddings, and protective layers, often used for long-distance communications and high-speed network connections. Characteristics of Various Network Cables: 1. Twisted-Pair Cable: It has good flexibility and bending capability, making it convenient for wiring and installation. Its low price makes it suitable for large-scale local area network construction and telephone line installation. However, its transmission speed and anti-interference ability are relatively low, suitable for transmitting low-speed data. 2. Coaxial Cable: It has good shielding effect and transmission rate, suitable for broadband network connections and TV signal transmission. Its disadvantages include a higher price and more complex wiring and installation process. 3. Fiber Optic Cable: It has the advantages of long transmission distance, high transmission speed, and strong anti-interference ability, making it suitable for long-distance communications and high-speed network connections. The data transmission process of fiber optic cable is not affected by electromagnetic interference or radiation interference, ensuring the stability and security of data transmission. However, the cost of fiber optic cables is higher, and the installation and maintenance difficulty is greater.
