Summary of Integrated Wiring construction experience

To sum up the experience of Integrated Wiring construction, the construction personnel should study well. Only by combining theory with practice can the cabling system be better implemented, so I studied some of the experiences of integrated wiring systems and the answers to common questions. I would like to share them with you here, hoping they will be useful to you.

1. Confirm the cable tension based on Integrated Wiring construction experience
When the cables are redundant in two terminals, they should be cut off according to the required length, rather than rolled up and bundled. The distance between the arc wound line segments at the connector of the cable shall not exceed 2 cm. Too long will cause large near-end crosstalk. During the authentication test, the NEXT end crosstalk cannot pass. At the joint, the outer protective layer of the cable needs to be pressed in the joint rather than outside the joint. Because when the cable is subjected to external tension, the stress is the whole cable. Otherwise, the stress is the metal part connecting the cable and the connector, which causes the terminal connection between the connector and the module to be unreliable. In the construction of cable wiring, the tension of the cable is limited, generally about 9 kg. Confirm the tension with the cable supplier. Excessive tension will damage the symmetry of the cable pair.

2. Specifications for cabling Techniques Based on Integrated Wiring construction experience
Some construction workers do not follow the 568A or 568B threading techniques when creating a line. Instead, they use the lines 1 and 2 to draw white and orange lines, lines 3 and 4 are white and green, lines 5 and 6 are white and blue, and lines 7 and 8 are white and brown, such a line can ensure smooth line during the construction process, but its line indicators are very poor, especially the near-end crosstalk indicators are particularly poor, will lead to serious signal leakage, this causes difficulties in accessing the Internet and indirect interruptions. Therefore, the project manager must remind production workers not to make such mistakes.

3. Anti-interference solutions based on Integrated Wiring construction experience
In the Integrated Wiring System, steel pipes are used for horizontal cables as much as possible, and bridges are used for laying trunk cables as much as possible. Then, during the construction process, do a Good Job of grounding cross-connection between steel pipes and steel pipes, between steel pipes and bridges, and between bridges and bridges. In such a pipeline, we will lay unshielded cables and large pairs of cables, which can effectively shield and reduce the impact of external interference on signal transmission of the Integrated Wiring System, make up for the shortcomings of the unshielded cabling system.

4. It is best to install the cable trough in the ceiling based on experience in cabling construction.
When installing the cable trough, consider multiple parties. Try to install the cable trough in the ceiling of the corridor, and the branch pipes in each room should be properly concentrated near the repair hole to facilitate maintenance. Centralized cabling should be implemented before the corridor ceiling, which not only reduces cabling time, but also facilitates the protection of cables already worn, without affecting the room decoration. Generally, the corridor is in the middle, and the average distance of cabling is the shortest. This reduces cable costs and improves the performance of Integrated cabling (the shorter the line, the higher the quality of transmission). avoid entering the room through the cable trough if possible. Otherwise, not only does the service charge, but also affects the room decoration, which is not conducive to future maintenance.

5. Experience in Integrated Wiring construction to distinguish the line sequence of large logarithm Cables
In actual construction, we often encounter 25 or 100 pairs of large logarithm cables, which is difficult to distinguish. Here, we will provide simple parameters for everyone. Take 25 pairs of cables as an example. The cables have five basic colors: white, red, black, yellow, and purple. Each basic color contains five colors, they are blue, orange, green, brown, and gray. That is, all line-to-line ~ The 25 pairs are classified into white-blue, white-orange, white-green, white-brown, and white-gray ...... Purple blue, purple orange, purple green, purple brown, purple gray.
For 100 pairs of cables, 25 pairs of cables are used as an example. 100 pairs of cables are divided into four groups with four-color ribbons: blue, orange, green, and Brown. Each group is wound together in the above way, and we can separate 100 lines. In this way, we can place the cables on the terminals of the 110 Distribution Frame one by one. As long as the Management Room and the devices adopt the same total cabling sequence, we can mark the cables, it can be used to transmit the phone conveniently.
