High cost-performance solution to build campus network

System design meets present and future teaching and research needs

University of Aeronautics and Astronautics Southeast District teaching and research building is divided into a~g block, 11 floors, underground 2, integrated wiring system all data points up to 16000余 points, all using the AMP six class system products, wiring system backbone using the AMP 8 core Single-mode fiber, to meet high-speed data transfer requirements. The network host room is located in the G block a weak electric motor room, voice host room is located in the basement of G block, a weak motor room, on the ground 1~11 layer with distribution lines, each floor distribution line through the weak main cable from the underground one layer of weak electric bridge to connect to the main wiring frame.

Detailed design of the system

In the system detailed design, the amp wiring according to the concrete situation of the building, comprehensively consider the actual application demand and the future development, the system structure should be able to adjust and expand according to the need of the business development change flexibly, easy maintenance management; The system is technically based on the latest international standards, Fully consider the advanced technology to support the future development of high-speed network applications, follow the "reasonable investment, planning and unification, based on the present, moderately advanced" guiding ideology, to provide intelligent building internal communication system development and application of a solid foundation.

The wiring system uses the star-shaped distributed management structure, from the structure of the entire wiring system by the work area subsystem, the horizontal subsystem, the management subsystem, the vertical backbone subsystem, equipment among subsystems, a total of five subsystems.

The working area subsystem is composed of the connection of the terminal equipment to the information outlet and the information outlet, which can either draw out the telephone or connect the data terminal or the other sensor and the weak current equipment through the socket. 6 types of information outlets can be installed using a traditional 110-wire tool, or you can use the amp for the SL series Information sockets design tool to install. The SL end-Connect tool simplifies the installation process, with a one-time termination and cutting off all conductors, which are more reliable and quicker to connect.

The function of the horizontal subsystem is to extend the line of the backbone subsystem to the user workspace subsystem, and the Electronic information Exchange service and voice transmission service of the horizontal subsystem, such as data and graphic image, will use six class four pairs of unshielded twisted pair (UTP) wiring.

The management subsystem defines the handover between the horizontal subsystem and the vertical trunk subsystem (trunk). According to the design of the comprehensive wiring system of the teaching and research building and the characteristics of the building structure, the network host room is located in the weak motor room on the first floor of the G block, and the Voice host room is located in the weak motor room of the G block underground, and the distribution lines are connected to each layer Part of the floor according to the user needs to consider a certain reservation.

Management Subsystem Equipment: Non-shielded wiring frame selection of advanced, practical fast-connect modular wiring frame, easy to maintain later. The AMP 6 type wiring frame satisfies the system connection and the channel performance request, has adopted the newly designed AMP SL module, each module may replace separately, the wiring frame uses the 9mm and the 12mm two kinds of labels, and uses the color coding, is easy to trace and the jumper. The wiring frame is connected with the data backbone from each distribution line, and the data transmission between each building is controlled by the server, network equipment and the switchboard.

The inter-device subsystem consists of a main wiring frame (MDF) and a jumper, it connects the output line of the central computer and the network equipment or the weak current main control equipment to the trunk subsystem, constituting the important link of the system computer network, and the route of all main distribution frame (MDF) is controlled by the jumper of the wiring frame.

Integrated cabling System products with high cost performance

Wiring system production technology in the last four years has been a huge development. Since the launch of the five products in 1992, manufacturers are becoming more proficient in how to improve the performance of twisted-pair wiring systems. We know that it takes a lot of parts to make up a system. The design and development of cable and connection hardware is important for a system with excellent performance. The performance of components and systems is determined by three basic parameters: near-end crosstalk, attenuation, and echo loss. On a 90-metre-long connection, the AMP 6 class system provides more than five types of performance 8.32db, and near-end crosstalk is one-eighth of the five-class standard.

The horizontal subsystem adopts the AMP six type unshielded twisted pair to meet the requirement of the desktop information network to support the data and voice function interchange. AMP six twisted pair with more sophisticated production technology, the same core of the cable is improved, the new twist density is more tight, the next performance is increased, the cable diameter is changed to 23AWG, and the insertion loss is reduced, while the cross fill design can keep the offset of the line pair and improve the next performance. Outstanding performance in the field test, next margin up to 10dB. The amp six type socket uses the new SL patent exterior design, reduce the length of cable untie, increase line pair spacing, improve the near-end crosstalk performance, at the same time using the V-terminal design, easy separation line pairs, free terminal compensation, the Second Circuit board on the socket can provide crosstalk compensation terminal compensation and signal separation.

In order to manage the convenience to achieve beautiful and practical effect, wiring between the use of the modular distribution of AMP wiring frame, the wiring frame is made of refractories, wiring racks and work area sockets can be flexible interchange, installation can be removed to the end. Line frame closed management, beautiful and flexible, can be customized according to the number, management jumper beautiful generous.
