Composition of structured cabling systems

The structured Integrated Wiring System provides users with the most reasonable cabling mode, and relies on its high-quality materials to change the traditional wiring, it laid the foundation for a modern building to truly become a smart building without changing communication lines within 15 years.
A structured cabling system consists of six subsystems and is defined separately:
I user subsystem: A User subsystem consists of a connection between a terminal device and an information outlet. It consists of a connector and an adapter.
I level subsystem: connects the information outlet and Management Sub-system wire jumpers. This connection is usually achieved by five or more 8-Core 4 pair twisted pair wires.
I Management Sub-system: the management sub-system consists of Interconnect and interconnect distribution frames. The management point provides a means to connect to other subsystems. Communication and interconnection allow the communication lines to be located or relocated to different parts of the building, so as to facilitate the management of communication lines, so that mobile terminal devices can be easily plugged in.
I backbone subsystem: implements the connection between the control center and various management subsystems by using computer devices and Programmable switch PBX. the commonly used medium is the large logarithm pair cable and optical cable.
Device subsystem: The device room subsystem consists of cables, connectors, and supporting hardware in the device room. It connects various devices in the public system. This subsystem connects the trunk line and the wiring intersection with public system devices such as PBX.
Subsystem of the I architecture group: Implements interconnection between buildings. The commonly used communication medium is optical cable or a large logarithm, and the optical fiber or a large logarithm is used between the main line and the building group.

It should be noted that for data communication, optical cables are used between the main line and the complex, and FDDI or ATM technology is used, the transmission throughput between systems can reach 100 Mbps, 155 Mbps, and 1000 Mbps. For the work zone, if three types of twisted pair wires are used, the current technology can reach 10 mbps10base-t), and the use of cat-5e twisted pair wires can reach 100 Mbps. For voice communication, a large logarithm is used between the main line and the buildings.
