I. Building Neutral cabling system (PDS)

Is a standard structured cabling system for transmitting voice data, images and other information

2. Six subsystems of integrated cabling

Workspace subsystem: information panel to computer

Horizontal subsystem: from the information panel of the workspace to the management subsystem, "generally star topology"

Management subsystem: composed of interconnection, interconnection and Icano, floor distribution frame

Vertical subsystem: connect equipment and management room, backbone cable is the key (twisted pair)

Equipment subsystem: located in the main computer room, composed of cables, connectors and related supporting hardware, connecting various public systems

Building complex (building) subsystem: connecting cables in different buildings, usually composed of optical cable corresponding equipment.

Third, a little bit of integrated cabling

1. Clear structure, easy to manage and maintain

2. Unified and advanced materials to meet the needs of future development.

3. Flexible and suitable for different needs

4. it is easy to expand, which not only saves the cost but also provides the reliability of the system.

IV. Materials used for wiring

1. Wire slot (metal slot or plastic slot)

Specification: 20mm x12 mm 25mmx12.5mm 40mmx20mm

2. Bridge frame: when more cables are laid, the bridge frame is used, or the U shield Acura wire slot can be placed on the bridge rack, which has high strength and good load bearing.

3. Distribution frame: it can gather the cables from each terminal to facilitate the maintenance and management of the cables on the whole floor.

V. Office network cabling

1. Requirement analysis and routing design

2. Calculation of material consumption: 1) Crystal head: nx4x (1 +) n = number of information points

2) Information module n (1 / 3%)

3) Cable amount C = [0.55x (lags) + 6] xn

VI. Office cabling implementation

1. Perforation in the wall

2. Installation of wire slot

3. Laying the cable: 1) intercepting the cable 2) marking 3) cable traction

4. Terminating cable

5. The equipment is on the shelf

6. Connectivity test
