Generic cabling system
1. System overview

The generic cabling system includes the construction of communication lines and integrated security system of data lines and monitoring systems, multimedia information release and guidance system, background music system, regional positioning system, nursing call system, queuing call system, building automatic control system and intelligent light control system, so as to realize the target network equipment investment equipment for network transmission and preservation.

The system is divided into five networks: internal network (including wireless), external network, equipment network, voice network and digital TV network, which are physically isolated from each other.

The generic cabling system adopts modular structure and star wiring mode to ensure the transmission of voice, data, graphics and images.

The project adopts the 10 Gigabit backbone Ethernet solution based on optical fiber. The system adopts modular design and star topology. After implementation, the generic cabling system will provide users with practical, flexible and scalable modular media access.

2. System technical requirements

(1). It complies with international standards ISO / iec11801 and TIA / eia568, can support 1000MHz data transmission, can support specific applications such as Ethernet and high-speed Ethernet, and fully ensure the high-speed and reliable information transmission requirements of computer network.

(2). It can adapt to the current and future technological development. All socket ports are modular standard components, which support data communication, voice and image transmission, and provide convenience for future function expansion and exchange.

(3). Fully comply with the national standard of the people's Republic of China, code for engineering design of generic cabling system for buildings and building groups (GB / t50311-2007) and code for construction and acceptance of generic cabling system for buildings and building groups (GB / t50312-2007)

3. Systematic recommendations

The design level of generic cabling is divided into basic type, enhanced type and integrated type. Combined with the use and management needs of users and considering the scientific and Technological Development in the next 10-15 years, the project adopts the comprehensive design level, and adopts the hybrid networking of optical fiber cable and six kinds of unshielded twisted pair. According to EIA / TIA 568a standard, the generic cabling system of the project includes five parts: work area, horizontal part, relay part, machine room part and management part.

Frame:
(1) Work area
The working area is composed of equipment connected between terminal equipment and information socket, including information socket, voice socket, socket box (or panel), connecting wire, etc. All terminal socket modules are arranged according to six standards, and the interface form is RJ45, which can realize the general exchange of telephone, network and terminal. In addition, select the corresponding wall socket according to the different requirements of the layout area of information points

The installation bottom edge is 300mm from the ground, which is consistent with the elevation of indoor strong current socket. Each information point can realize data and voice exchange through jumper management of floor distribution frame or main distribution frame. All information sockets, voice sockets, panels and distribution frame management system modules are marked, and the marking symbols represent the application and physical location of different characteristics. At the same time, the technical requirements and specifications of different building functions (apartment, supporting service building and medical building) are considered.

(2) Horizontal part
One end of the horizontal cable is connected to the information socket, and the other end is connected to the distribution frame of the machine room.

All horizontal cables adopt 6 kinds of 8-core unshielded twisted pair buried pipes. The six horizontal lines can support transmission rates up to 1000mbp and ATM 622Mbps, which can meet the requirements of voice and data transmission, as well as the transmission of multimedia information such as graphics and images.

(3) Trunk part

In order to support Gigabit Ethernet and higher data rate applications in the future, the data vertical relay adopts 62.5/125 μ  M six core multimode fiber. Optical fiber has the characteristics of large capacity, high speed and strong confidentiality. Multimode fiber has high optical coupling rate. When the bending radius is greater than 10 times its diameter, the signal transmission will not be affected. It is a backbone transmission cable conforming to IEEE 802.5 FDDI and EIA / TIA 568 standards. Voice vertical relay adopts three kinds of 100 pairs of large pairs of copper wires, which can fully meet the communication technology needs in the next 10 - 15 years. The main lines of the whole system are concentrated in the aggregation layer switching room.

(4) Complex construction

The data rate transmission between buildings is 10GB Ethernet, outdoor 24 core single-mode optical fiber and backbone transmission cable are adopted, which comply with IEEE 802.5 FDDI and EIA / TIA 568 standards. The main line of Jianyin group adopts three kinds of outdoor 100 pairs of large pairs of copper wires.

(5) Equipment room

The main distribution room adopts the standard cabinet installation mode, and the floor distribution room adopts the wall assembly box installation mode. In each distribution room, the installation of cables or optical cables shall be carried out after grouping, putting on racks, arranging and binding, so as to ensure the safety of cables and the neat and beautiful arrangement of lines.

(6) Manage
Considering the needs of future expansion, the ports of the distribution frame have a certain margin. The main optical fiber is terminated on the optical fiber distribution frame, and SC coupler and SC connector are selected for connection.
