Overview of network cabling projects in Integrated Wiring

Overall Design of network cabling

On the basis of fully understanding of network requirements, we should make scientific ideas and ideas about network cabling, and position the overall design of the integrated bus cabling system engineering. The overall design is the most important basis for Engineering Construction. Only after a reasonable overall design of the Integrated Wiring System can the subsystems be reasonably designed.

Network Cabling engineering design overview

The network integrated wiring engineering design is the key to whether the entire wiring project can meet user needs and provide a high-performance and cost-effective network system. The network wiring engineering design mainly includes the following aspects.

Survey buildings and construction sites to obtain floor plans of buildings.

Analyze user requirements. Evaluate the user's network requirements and communication requirements, and determine the data and voice transmission media, information point distribution, number of floors, number of buildings, and network system levels based on the recent development plan.

Select and design a route. Determine the direction, laying mode, and materials of the horizontal system, vertical subsystem cable, and trunk cable between buildings.

Select the wiring method.

Cable and wiring products.

Wiring drawing design.

Exchange comments with users and improve wiring drawing design.

Modify the wiring drawings as appropriate based on the actual conditions encountered during construction.

An open star topology should be used to design the Integrated Wiring System.

Each branch subsystem in this structure is a relatively independent unit. Modifications to each branch unit system do not affect other subsystems. As long as the node connection is changed, the network can be converted between various types such as star, bus, and ring. Typical configuration and function combinations of Integrated Wiring and wiring devices are shown in Figure 4-1.

In the overall network design, three factors should be considered: What cables are used, what routes are used, and what laying methods are used. The optical fiber, twisted pair, single-mode optical fiber, or multimode optical fiber are required for the transmission distance and transmission rate. the physical structure of the building and the relative location of the building determine the route laying of the cable; the damage of indoor and outdoor environments and the full use of existing facilities determine the laying of cables.

In a sense, wiring design not only determines network performance and wiring costs, but also whether the network can communicate normally. For example, super-s unshielded twisted pair wires can only support transmission rates of Mbit/s. Multi-mode optical fiber cables are used between buildings that are far away from each other, leading to communication failures between buildings; when unshielded twisted pair wires are used in places with severe electromagnetic interference, communication may fail. Therefore, all thousands of factors should be fully taken into account when designing the cabling project, and various Cabling Standards should be strictly implemented.

The general overview of network cabling is here, and I hope you will have some gains.
