Section 3: Relationship between Cable and Communications Engineering
3、1 Interdependence between Cable Systems and Communication Networks
Cable systems play a crucial role in supporting communication networks by transmitting electrical power, data, and communication signals over long distances. On the other hand, communication networks rely on robust cable systems to provide reliable connections between devices and users. For example, wireless communication technologies such as WiFi rely on local area networks (LANs) built on fiber-optic or copper cables to transmit data packets between devices. Similarly, satellite communication systems depend on high-speed optical fibers to transmit data between ground stations and Earth orbiting satellites. Therefore, the relationship between cable systems and communication networks is interdependent and mutually reinforcing.
