Cable systems are networks that use cables to transmit data, electricity, or signals over distances. They are commonly used for various purposes, such as providing internet and television services to homes and businesses. These systems can include fiber optic cables, which carry data as light signals, or coaxial cables, which are often used for cable TV. In addition to communication, cable systems are also essential in industries like power distribution. High-voltage cables transport electricity from power plants to homes and businesses, ensuring that we have the energy needed for daily activities. Overall, cable systems play a crucial role in modern infrastructure.
