Design and construction of structured integrated wiring system

The Structured Integrated Cabling system (structured Cabling Systems, abbreviated SCS) adopts modular design and layered star topology. It adapts to the wiring system of any building or building. Its representative product is the building and architectural complex cabling system (premises distribution systems, abbreviation PDS). In addition, there are two advanced systems, the Intelligent building wiring system (IBS) and industrial wiring system (IDS). Their principles and design methods are basically the same, the difference is the PDS in business environment and office automation environment.
　　
PDS generally uses modular design and physical layered star topology to transmit voice, data, images and various control signals.
　　
The PDS structure can be divided into 6 separate subsystems (modules).
　　
1. Workspace (terminal) subsystem (WORK area Sursystem)
　　
Work area wiring subsystem from terminal equipment to information outlets of the line (or flexible cords) group lines, it includes the assembly of flexible cords, connectors and the expansion of the cable required to connect, and between terminal equipment and I/O bridge, information sockets are wall, floor, table, soft base type of a variety of standards have RJ45/RJ11 single, double, Various types of porous.---http://bianceng.cn (learn computer)
　　
2. Horizontal wiring Subsystem (horizontal subsystem)
　　
The horizontal wiring subsystem connects the cable from the floor distribution frame to the information outlet on each user's work area, usually on the same floor. 5-Type 8-core 4 pairs of twisted pair can usually be used, conforming to or exceeding Eia/tia 1568 standard
　　
3. Vertical trunk Subsystem (RISER backbone Sursystem)
　　
The vertical trunk subsystem is composed of large logarithm multi-core copper cables or optical cables between each floor distribution frame and the main distribution frame, or the combination of the two. It is the nerve center of the integrated wiring system, its main function is to connect the main wiring frame system with each floor distribution system.
　　
4. Management Subsystem (Administration subsystem)
　　
The management subsystem is composed of floor wiring frame. Its main function is to connect the vertical dry cable with the horizontal wiring subsystem of each floor. Cabling system's advantages and flexibility are mainly embodied in the management subsystem, as long as a simple jump line can be completed any structured cabling system of information outlets for any kind of intelligent system connection, greatly facilitate the layout of the line and network terminal adjustment. Optical fiber connection, to use a fiber-optic continuous box (LIU), the box can have more than one St connector mounting holes, the box inside the line bending design should be in line with 62. 5/125 Micron multimode Fiber bending requirements, fiber connectors with stii, made of ceramic materials, the maximum attenuation of signal is less than 0. 2dB, optical coupler can be used as multimode optical fiber and network equipment or fiber connection, wiring racks and fiber junction boxes are usually located in the weak wells or equipment, used to connect other subsystems, and they through the jumper management
　　
5. Inter-equipment subsystem (equipment Subsystem)
　　
The subsystem of the equipment is composed of the main wiring frame and the public equipment. Its main function is a variety of public equipment (such as computer host, digital program-controlled exchange, various control systems, network interconnection equipment) and the main wiring frame connected. The subsystem also includes electrical protection devices.
　　
6. Complex to connect subsystem (Campus backbone Subsy5tem)
　　
The subsystem refers to the connecting system of main distribution frame in main building extending to the main distribution frame of other buildings. Similar to the vertical subsystem, it is usually connected by a cable or a large logarithmic copper cable. It is part of the entire cabling system (including transmission media) and supports the provision of hardware required for communication between buildings, including cables, optical cables, and electrical protective equipment that prevents surge voltages of cables from entering buildings.
