The Structured Cabling System is a specially-devised, universal and optimally organized cabling infrastructure unit for buildings or building complexes. The system is used for computer, telephone, security and fire alarm system cable installation. It covers the whole building and ensures installation costs are minimized. Once the building is in use, additional passive cabling installation is easy to perform. The full system is made up of subsystems interconnected with special passages that join under a single switchboard. The system is perfectly durable and fully justifies the relevant costs. The structured cabling system related solutions are carried out according to the TIA, EIA and ISO standards.
