Eight common problems to avoid during house network cabling

Exercise caution when wiring the house network. This is a very complicated and tedious task. If it is not done well, problems may occur during later use and further troubleshooting, it is troublesome to solve the problem. Some experienced wiring personnel, or even electricians, take into account the work of wiring, which will cause many hidden dangers to the line. The following eight problems are the most common problems during cabling:

I. Use different lines for voice and data services

Considering the cost, many companies used to use different network cables of different specifications and types in their voice and data services. Because the voice business does not have high requirements on line conditions, it can be up to standard with a single wire, therefore, providing a cheaper line for the voice service can ensure that the data line receives a large portion of the budget.

Till today, although the cost of Integrated Wiring is still a small expense, the biggest expense has become the cost of human resources, and the line itself does not occupy the highest investment share. In addition, with the popularization of the voice telephone technology, the voice service has become a project in many environments where data requirements depend on data-level network cable support. In fact, if the company does have such requirements, you only need to select the appropriate voice phone equipment, you can use the existing data cable and the built-in Ethernet switch of the voice phone equipment to meet the corresponding requirements, this avoids the waste of money caused by repeated cabling.

In short, before the beginning of work, we cannot simply assume that the voice service only needs to use the old three-class line. If you need to deploy a separate line for the phone, you should ensure that its performance can reach the level that supports the data line.

2. The network cable and the "interference" device are in the same area

In the real environment, not only wires can interfere with data lines. Lighting fluorescent lights, motors, and related equipment that can produce electric or magnetic interference can have a serious impact on network cable data transmission. Therefore, when wiring, we need to ensure that the line is away from the region where these interference sources are located.

3. No Prospective Planning for the overall network

At present, Gigabit Networks have been popularized, but many companies still need to continue to use network connections from MB to the desktop. For example, some companies need to move to new office locations, which requires re-deployment of network lines. In this case, traditional network cable technology that can meet the needs of current applications should be adopted, we can still choose a new network cable technology that can be continuously upgraded in the next few years. Note that the cost of human resources is the highest part during project operation. Although it seems unreasonable to select a more advanced wiring scheme during the implementation of the actual project, we recommend that you consider using products with better quality as much as possible. In this way, your enterprise will not be embarrassed when facing higher network requirements for a long period of time. Therefore, ensuring that the network cabling technology used is not outdated is a must for network cabling personnel.

4. No effective management of lines

Generally, you will think that increasing the number of lines will help the existing system. The increase in Trapezoidal racks and the subsequent rack-based line management will indeed lead to an increase in operating costs. But it can also make daily maintenance work very simple. It should be noted that the line management work will not be automatically terminated because of the final security of the project. When more and more lines are added, the reality will change. Therefore, we need to identify cables, classify cables by color, or take special measures of other types to ensure that relevant lines can be easily identified under any circumstances.

V. Parallel layout of Network cables and cables

The "Twisted Pair" unshielded twisted pair mode is used for data transmission. The magnetic field produced by low voltage running through wires is an important part of the communication chain. When the unshielded network cable is parallel to the wire, the magnetic field interference will occur, which will lead to a large number of repeated and garbled information in the transmitted data. In many cases, this will lead to the failure of effective transmission between two locations, the transmission rate will rapidly decline, and frequent problems requiring repeated transmission.

6. Ignore the actual distance limit

Before wiring, confirm the distance and range of the connection. For example, the distance between common twisted pair wires and typical Ethernet cabling is 100 meters in a gigabit network. If the company chooses a technology of 10 Gigabit or 40 thousand Gigabit, it should follow the specific design distance as the standard. For example, if the company intends to use twisted pair wires to run a 10-Gigabit network at a distance of more than 100 meters, it must select a 6A or higher network cable.

7. Ignore line testing

After wiring is completed, various tools should be used to test each line to ensure that they can all meet the predefined requirements. The work involved includes verifying the transmission distance and cable specifications. In the case of a gigabit network, it is also necessary to verify the line to ensure that the corresponding requirements can be met.

8. No reasonable planning for new lines

When we need to use Ethernet switches in the network to handle the newly added lines, we need to specifically note that before scientific and reasonable planning, the use of Ethernet switches brings unknown factors and unstable risks to the entire network. Generally, users who use micro-switches only need to add one or two ports, so they do not need to plan traffic. The addition of additional ports may cause problems. If a new service requires a large amount of network resources to support it, try to avoid bottlenecks. Therefore, it should be noted that, in the absence of an absolute need to increase the number of switches and network ports, we should try to consider other methods for network resizing, for example, add new lines to expand the network scale.
