V. Composition of the integrated wiring system

The integrated wiring system consists of six subsystems, namely, the complex subsystem, the subsystem of equipment, the vertical trunk subsystem, the management subsystem, the horizontal subsystem and the working area subsystem. Theoretically speaking, the large-scale wiring system needs to use the copper medium and the optical fiber medium component to integrate six subsystems together, according to the IBDN design idea, this system design plan includes:

Complex subsystem

The use of Multimode optical cable to connect the new and old radio and television buildings, industrial and commercial center computer room mainframe and network equipment;

Vertical Trunk Subsystem

The vertical trunk subsystem realizes the connection between the data terminal equipment, the switchboard and the management subsystem.

Subsystems between devices

Adopt Bix-Hop type wiring frame, connect the switch, use the fiber terminator to connect the host and network equipment, the subsystem of the equipment is to provide information management and information transmission service for all kinds of information equipment (such as computer network interconnection equipment, switchboard, etc.) in the integrated wiring system. For computer network system, it includes network hub (hub) equipment, network intelligent switching hub (intelligent switcher) and equipment connection line. We have adopted the standard 19 "cabinet, you can integrate these devices (Switch, Hub) into the cabinet, easy to unified management." It connects the output line of the computer and network equipment through the main trunk subsystem, constituting the important link of the system computer network, and it controls all the routes of the total distribution frame (MDF) through the jumper of the matching frame.

Horizontal Subsystem

The line of the subsystem of the equipment is extended to the user work area, the data part and the speech part use the ISDN five kinds of twisted pair; the function of the horizontal subsystem is to extend the line of the backbone subsystem to the user workspace subsystem. The data, graphics and other electronic information exchange services of the horizontal subsystem will use four pairs of Super 5 unshielded twisted pair (Cat). 5 UTP) wiring. Super 5 type unshielded twisted pair is the best high quality transmission medium at present, its performance index conforms to ansi/eia/tia-568 standard completely, can guarantee the transmission rate reaches and surpasses 100MBps in the range of 100 meters. Based on the maximum distance of 5-type UTP to support 100MBPS transmission, the design line is less than 90 m from the wiring frame to the farthest end (workspace).

The horizontal subsystem is composed of 8-core unshielded twisted-pair wires. Commonly used twisted-pair lines have 3 types of lines and Super 5 type line. The 3 line can be used for telephone and 16Mbps data transmission, and the speed of Super 5 line transmission data can reach 100Mbps. In order to adapt to the requirements of future expansion and to maximize the protection of investment, this program uses all Super 5-class line mode.

Work Area Subsystem

To provide users with a IBDN standard, but also to meet the high speed data transmission standards. The workspace subsystem is composed of jumper and information outlets connected to the information socket by terminal equipment, which can connect the computer or other terminals through the socket. The twisted end of the horizontal system ends up here. Each panel has a Super 5 type socket, and the socket is mounted on the panel. Installed in each work location. Socket selection of 8-core RJ45 type. The jumper is used to connect the socket to the PC. The jumper ends with a RJ45 plug. Consider equipped with a double hole socket. The computer, the telephone may according to the user's need, jumps randomly.

Management Subsystem

Wiring frame Management module, and horizontal twisted-pair connection to choose advanced Universal 19 "standard modular wiring frame." The computer wiring uses the single hop way, the jumper jumps between the hub and the wiring frame. Jumper adopts Super 5 type UTP,RJ45 connector. You can use the hub jumper with yellow label rope, consider adjusting the distance after the fixed-length production, each jumper has passed five kinds of tester's multiple index test, fully meet the standards of the jumper specifications, support more than 100M data transfer rate. Marking rope added at both ends of the jumper, the label corresponding, to avoid the future management of the inconvenience of checking lines, very easy to manage.

This system uses the Super Five class standard Information module to connect the data and the speech equipment, has laid the solid foundation for the later computer system expansion.

VI. selection of integrated wiring products

The building uses the optical cable connection, the backbone network is the hundred Gigabit Optical fiber Ethernet. Indoor wiring in buildings we use IBDN structured wiring system, from end to end using Super Five connector products, support Ethernet, Token ring, CDDI, ATM and multimedia technology, and to open the principle of supporting a large number of manufacturers of products and equipment.

1). Information sockets: Both data and voice are used in MDVO modular type five type information outlets.

2). Transmission medium: Level-data and voice are IBDN plus super five type unshielded twisted pair;
Buildings--The use of outdoor six-core multimode fiber.

3). Wiring frame: The data adopts IBDN fiber terminal box and PS5 HD series modular wiring frame.

4). Jumper: The data section uses two-core SC-SC fiber jumper and high speed module jumper.

Layout system pipe Groove design and pipeline laying

Due to the installation of unshielded twisted pair, the grounding requirements are not high, can be connected with the cabinet Main Line groove ground.

The specification of the Groove is as follows: The cross-section area of the groove is left at 40% of the surplus for expansion, and the cross section of the 5-type twisted pair is 0.3 square centimeters.

Groove installation, should pay attention to the isolation of strong wire groove. Wiring system should avoid with strong electric line in no shielding, distance less than 20cm parallel walk more than 3 meters. If it can not be avoided, this section of the groove needs to take shielding isolation measures. The cable pipeline into the furniture from the nearest ceiling trough to the ground along the wall, and from the ground boring groove buried under the furniture partition.
