The original six types of wiring system construction, management and other aspects of the existence of disadvantages, as more and more users use the six types of system, so the big project implementation business are more experienced, can be installed. However, there are still some engineering teams using backward construction technology and management mechanism, resulting in the acceptance test can not pass, rectification and unable to start the passive situation. Why should you care about installing a Class six system? Because Class 6 cabling systems can provide 2.5 times higher bandwidth than Class 5 cabling systems in terms of transmission rate, the more advanced copper cables are, the more sensitive they are to external anomalies. As transmission rate rising, installation correctly or not will influence the performance of the system, unreasonable pipeline design, non-standard installation steps, inadequate management system, all the test results of six kinds of wiring (including electrical properties and physical properties), and some are difficult to repair the problem. Therefore, in order to ensure the high quality of installation, the construction personnel of the six types of cabling system must perform in accordance with the specifications required by the international standards, and must strictly accept and test, and ensure that every application protocol passes the qualification, not only a certain application protocol. This point is especially worth emphasizing, because some users are not careful in the acceptance, often stay in the "pass and pass" level, the result is that the cabling system can not be high-quality to carry advanced network applications.
