The architecture of Chengdu integrated wiring system: (1) Work area The work area is composed of equipment connected between terminal equipment and information sockets, including information sockets, voice sockets, socket boxes (or panels), connecting cords, etc. All terminal socket modules are laid out according to six types of standards, and the interface form is RJ45 type, which can realize the universal interchange of telephone, network and terminal. In addition, according to the different use requirements of the information point layout area, choose the corresponding wall socket Chengdu integrated wiring. The bottom of the installation is 300mm from the ground, and the elevation is set uniformly with the high-power sockets in the room. Each information point can realize the exchange of data and voice through the jump management of the floor distribution frame or the main distribution frame. All information sockets, voice sockets, panels and distribution frame management system modules are marked, and the marking symbols indicate the application and physical location of different characteristics. And also consider the similarities and differences of the technical requirements and specification requirements of different building functions (apartments, supporting service buildings, medical buildings). (2) One end of the horizontal cable of the horizontal part is connected to the information socket, and the other end is connected to the distribution frame between the equipment. All horizontal cables are laid in concealed way with six types of eight-core unshielded twisted-pair steel pipes. The six types of horizontal lines support up to 1000Mbp, ATM622Mbps transmission rate, which not only meets the transmission of voice and data; but also meets the requirements of multimedia information transmission such as graphics and images. Chengdu integrated wiring. (3) In order to support Gigabit Ethernet and higher data rate applications in the future, the trunk line uses 62.5/125μm six-core multimode fiber. The optical fiber has the characteristics of large capacity, high speed, and strong confidentiality. The optical coupling rate of multimode optical fiber is high. When the bending radius is greater than 10 times its diameter, it does not affect the signal transmission. It is in line with IEEE802.5 FDDI and EIA/TIA 568. Standard backbone transmission cable. The voice vertical trunk line uses three types of 100 pairs of large logarithmic copper cables, which can fully meet the requirements of communication technology in the next 10 to 15 years. The trunk lines of the entire system are gathered into the switch room of the aggregation layer. (4) The transmission of 10 Gigabit Ethernet data rates between some of the building groups uses outdoor 24-core single-mode optical fibers and trunk transmission cables that comply with IEEE802.5 FDDI and EIA/TIA 568 standards. The trunk line of the voice building group uses outdoor three types of 100 pairs of large logarithmic copper cables. (5) Standard cabinet installation is used in part of the main wiring closet of the equipment room, and wall assembly line box installation is used in the floor wiring closet. In each wiring closet, after the completion of grouping, racking, cable management, and bundling, the installation of cables or optical cables is carried out to ensure the safety of cables and the neat and beautiful layout of the cables in general. (6) Management Considering the needs of future expansion, a certain margin is left on the ports of the patch panel. The backbone optical fiber is terminated on the optical fiber distribution frame, and the SC coupler and SC connector are used for the connection.
