(1) Office area subsystem (WORKAREASUBSYSTEM)
The office area subsystem is composed of devices connecting user terminal equipment to information sockets. It includes socket panels, connectors and extension cords required for connection. Information sockets include wall, ground, and desktop types, and the standard is RJ45. /RJ11 single, double, multi-hole and other models.
2) Horizontal subsystem (HORIZONTALSUBSYSTEM)
The horizontal wiring subsystem connects the cables from the patch panel to the information sockets in each office area, generally on the same floor. Usually, Category 3 or Category 5, 8-core, 4-pair twisted pair is used. Category 3 or Category 5 twisted pair is composed of 8 24-AWG (0.511mm) copper wires, which conform to the EIA/TIA-568A standard.
3) ADMINISTRATIONSUBSYSTEM
The management area subsystem is composed of floor distribution frame. Its main function is to connect the vertical trunk cable with the horizontal wiring subsystem of each floor. The flexibility and advantages of the wiring system are mainly exerted on the management subsystem. As long as the line is simply jumped, any information socket of the structured integrated wiring can be realized to realize the connection to any type of intelligent system, which greatly facilitates the line re-connection. Deployment and adjustment of network endpoints. When connecting optical fibers, use a fiber optic splice box (LIU). There can be multiple SC connector mounting holes in the box. The line bending design in the box should meet the bending requirements of 62.5/125 micron multimode fiber. Made of ceramic material, the maximum attenuation is 0.2dB, the optical coupler can be used as the connection between multi-mode optical fiber and network equipment or optical fiber splicing installation. Vertical trunk systems and manage them through jumpers.
4) Vertical backbone subsystem (RISERBACKBONESUBSYSTEM)
The backbone subsystem provides the routing of the backbone cables of the building, and is the nerve center of the structured integrated wiring system, realizing the connection between the main distribution frame and the intermediate distribution frame. It is generally recommended to use large-pair twisted pair cables and optical fibers as the backbone transmission medium.
5) Main management area subsystem (EQUIPMENTSUBSYSTEM)
The main management area subsystem connects trunk crossovers and cabling crossovers to using system equipment. It is composed of cables and connectors between the main equipment and related supporting hardware to interconnect various equipment of the public system.)
