Generic cabling project of network cable manufacturer
Serve the equipment and spare parts in the security field, undertake security monitoring projects, provide monitoring engineering solutions, provide security monitoring equipment and surrounding accessories, and provide smart home products. Adhering to the business philosophy of "professionalism, integrity and high quality", we provide first-class products and services.
Generic cabling project is a systematic project. In order to ensure the quality of generic cabling project, we must take some safeguard measures.
These construction quality assurance measures are as follows:
1. Detailed drawings at the design stage shall be prepared, which are very important.
Don't think it's very simple. A good generic cabling system design drawing can save your cabling time and some on-site problems encountered in the process of generic cabling system. Those who have done building generic cabling system engineering know that there is not only weak current in the building, but also strong current, fire fighting, air conditioning, etc.
2. During the construction process, the construction plan shall be made to cope with continuous changes. Because sometimes plans can't keep up with changes. I've encountered such projects before.
3. It is necessary to know the progress of other parts of the whole project in time, so as to adjust the construction plan in time.
4. Construction personnel shall be strictly required. The line shall be neat and clear.
5. Label identification shall be made.
The generic cabling tester performs many tests within the preset frequency range and compares the results with the limit values in TIA or ISO standards. These test results can determine whether the link meets the requirements of a certain class or level (e.g. super class 5, class 6, level D).
Verification tester and qualification tester are usually tested with channel model, and generic cabling tester can also test permanent link mode. The permanent link model is the longest installation mode for generic cabling.
In addition, the generic cabling tester can not only side network cable, but also support optical cable test, provide advanced graphics dispute capability and provide richer reports. An important difference is that only the certification tester can provide the ability to determine whether a link is "pass" or "fail".
Wiring test can not improve the channel performance of generic cabling, but only confirm whether the installed cables, relevant connecting hardware and their processes can meet the design requirements.
Sometimes some problems occur during wiring test, mainly in the following aspects:
1. Near end crosstalk failed. The reason may be the problem of the near end connection point, or the string pair, external interference, short circuit of the far end connection point, performance problems of link cable and connection hardware, different products and cable termination quality problems, etc.
2. Wiring diagram failed. The reason may be the open circuit, short circuit, crossing or rupture of the connectors at both ends, or the wrong jumper, etc.
3. Attenuation failed. The reason may be that the cable is too long or the temperature is too high, or there may be a problem with the connection point, or there may be a performance problem with the link cable and the connection hardware, or it is not the same kind of product, or there may be a problem with the quality of cable termination.
4. Length failed. It may be that the cable is too long, open circuit or short circuit, or the total length of equipment wiring and jumper is too long.
