Cable installation involves the process of setting up various types of cables, such as fiber optic, coaxial, or network cables, to facilitate communication and data transfer. This process includes planning the layout, selecting appropriate materials, and ensuring that the cables are securely connected to devices like routers and modems. During installation, technicians may need to drill holes, run cables through walls, and connect them to service providers. Proper installation is crucial for optimal performance, as it minimizes signal loss and interference, ensuring reliable connectivity for homes and businesses.
