4. 1 Workspace subsystem
It consists of terminal equipment wiring and information socket. Information sockets are distributed in classrooms, laboratories, offices, management rooms, student dormitories and other places, all using more than five information modules.
4.2 Horizontal Wiring Subsystem
The trunk subsystem line extends to the user's work area, and the horizontal distribution subsystem in the park adopts super 5-class 8-core unshielded twisted pair.
4.3 Vertical trunk subsystem
All the vertical trunk subsystems in the park are connected by multimode optical fiber, and each management subsystem reserves more than 5 kinds of 8-core unshielded twisted pair as backup for vertical trunk routing.
4.4 Management subsystem
It is distributed in the wiring room of weak current shaft of each floor, managing the horizontal wiring of each floor and connecting the corresponding network equipment. Each wiring room has a 19 "standard cabinet, which requires related disciplines to adopt ventilation facilities to avoid electromagnetic interference and protect the normal operation of equipment.
4.5 Inter-equipment subsystem
Use quick connect distribution frame to connect the host and network equipment. The computer room subsystem is located in the library network center and the student dormitory network sub-center.
4.6 Building complex subsystem
Due to the long distance between the network center and the dormitory network sub-center, considering that the transmission distance of gigabit network multimode fiber is only 550m, 12 core single-mode fiber is used for connection. From the network center and sub-center to the building, considering the recent school use, equipment investment, long distance and other factors, multimode fiber and single-mode fiber are used to connect, and single-mode fiber is reserved in each building for the future development of the whole network system.
