Copper Structured Cabling System (CSCS) is a communication system that consists of copper cables, connectors, panels, and other components used to provide data, voice, and video transmission between devices in buildings and structures.

CSCS allows for the creation of computer networks and other communication networks that provide fast and reliable data transmission over distances of up to several hundred meters. The system includes category 5, 6, and 7 cables, which have different data transmission speeds and other parameters.

CSCS is used in commercial buildings, offices, schools, hospitals, and other facilities where a reliable and fast communication network is needed for multiple devices and users.
