The integrated wiring system is the foundation of enterprise informationization, the nervous system of the building, and a standard structured wiring system based on the transmission of voice, data, images and other information. It connects voice and data communication equipment, switching equipment and other information management systems to each other. The system consists of 6 independent subsystems: a work area subsystem, a horizontal area subsystem, a management subsystem, a trunk subsystem, an equipment room subsystem, and a building group subsystem.
Refers to the information socket of the wiring (horizontal) wiring system, the connection cable extending to the workstation terminal equipment and the adapter. The service area of a work area can be estimated from 5 to 10 square meters. Each work area is equipped with a telephone or computer terminal equipment, or according to user requirements. The UTP / FTP jumper in the working area is made of flexible wire material, that is, the core wire of the twisted pair is a plurality of thin copper wires. Now the mainstream jumpers are Cat5e or Cat6 twisted pair cables, and the maximum length should not exceed 5M.
Refers to the user information socket from the floor wiring closet to the work area. It consists of horizontal cables and intermediate wiring equipment. Use star topology. Each information point needs to be connected to the management subsystem. The maximum distance from the back port of the distribution frame of the management room subsystem to the information outlet in the work area should not be greater than 90m. The total length of the terminal jumper in the work area and the jumper of the device connected to the device should not exceed 5M. The construction of horizontal wiring system is the largest and most important work in comprehensive wiring. It is not easy to change after the construction of the building is completed. Therefore, strict construction is required to ensure link performance. Currently, horizontal cables generally use twisted-pair cables such as Cat5e or Cat6 and Cat6A. For high-speed applications, optical cables should be used.
It is located in the floor wiring room and weak current well, it is the place where the horizontal system cable is terminated, and it is also the place where the backbone system cable is terminated. Users can change, add, transfer, and extend cables in the management subsystem to change cable routing. The management subsystem provides a means to connect with other subsystems, so that the entire wiring system and the equipment and devices connected to it form an organic whole. It is a concentrated expression of the flexibility of the integrated wiring system. At the management point, each termination field is marked with a marker insertion bar according to the application environment.
Vertical trunk subsystem:
It consists of cables connecting the main equipment room to the wiring room on each floor. Its function is mainly to connect each layered distribution frame with the main distribution frame. Trunk cables are used to provide communication channels between floors, so that the entire wiring system forms an organic whole. According to different terminal equipment, different trunk cables can be selected, large logarithmic cables can be used for voice transmission, and optical cables or twisted pair cables can be used for data transmission.
It consists of various main equipments such as building line equipment, telephone, data, computer, etc. of the integrated wiring system and its security wiring equipment. All incoming terminals in the equipment room should use color coding to distinguish the wiring area for various purposes. The location and size of the equipment room should be determined based on comprehensive consideration of the quantity, scale, and optimal network center of the equipment.
The building subsystem consists of the telephone, data, and television systems of two or more buildings. A building complex integrated wiring system includes cables and wiring equipment (CD) that connect the buildings to form a building group. system. The sub-groups of the building group should be laid in underground pipes. The copper or optical cables laid in the pipes should follow the design rules for telephone pipes and access holes. In addition, at least 1 or 2 spare pipe holes should be reserved during installation for expansion. When the subsystems of the building group are laid in a directly buried trench, if other image and monitoring cables are buried in the same trench, an obvious common sign should be set up. The cable introduced by the telephone office should enter a flame-retardant joint box and then be connected to the protective device. The building group subsystem realizes the interconnection between the buildings. The common communication medium is optical cable, and the optical fiber cable is used between the main line and the building group.
