Structured cabling is the system under which  all low voltage wiring and digital signals which are used to transfer and exchange of data, signals, and communications control are deployed  to a single cabling system.

Subsystems in which structured wiring is used in modern facilities include voice-data networks, video, audio, security, building automation, lighting, and any other system  planned, designed, installed,
and configured as a single system.

With respect to materials and equipment used in  a structured cabling system, it consists of:

• wiring
• passive equipment
• active equipment

As regards the structure, it is divided into:

• core network (backbone) that includes the central distribution network of digital signals from the data center to the individual subsystems or to the local business checkpoints
• Horizontal cabling that includes the distribution network from the control center of each subsystem with the equipment of end user positions
