The acceptance of the Integrated Wiring System is a special concern for the design and construction personnel. Many people may not understand the acceptance of the Integrated Wiring System. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things.
When the first installation of cat6 copper cable systems by an engineering engineer who often thinks that he has several years of construction experience, he will be surprised to find that the project's acceptance is so difficult: during the first test, the percentage of unqualified and rectification is sometimes dozens of percent, rather than a few percent of the installation of cat5e copper cable systems. It is also difficult to make the rectification to pass the test, it takes multiple times. Most of the engineers who are facing this situation will explore whether there are any new ways to learn about the installation of cat6 copper cable systems, A small number of arrogant people may even doubt whether the production quality of the products used meets the requirements of category 6, because the acceptance of the on-site Integrated Wiring System is affected in two aspects: the production quality of the product and the technical level of the project engineer.
In fact, any product of the six categories sold in the market that is publicly stated must have an independent and authoritative third party with sufficient certification to support it, there will also be projects that belong to different regions or industries, and they have successfully passed the project acceptance. Engineers should find the cause from themselves.
There is no new method for the installation of cat6 copper cable systems. They are all construction specifications executed when cat5e is installed. The installation of cat6 copper cable systems requires stricter implementation of the construction specifications executed when cat5e is installed. This is precisely the weakness of the six-class acceptance engineer, because many of them did not strictly implement these construction specifications when installing the cat5e copper cable system, the more tolerant cat5e masks their roughness. This situation cannot all be attributed to the project owner himself: in a social environment, there are indeed end users or supervisors, because of lack of professional knowledge or due to well-known reasons, the so-called "activation and acceptance" is adopted for the acceptance of the integrated wiring system, that is, as long as one or more application protocols can be activated in the wiring system, such as a phone call, or MB Ethernet can run, it indicates that the Integrated Wiring System has passed the acceptance test. The key is that it does not need to pass the field test of the tester. The reason is that the cabling system cannot be used independently. It is used to run certain application protocols on the cabling system. Of course, it must be based on the trial activation. What is the significance of testing a pile of data? This approach seems reasonable and confusing to non-professional decision makers.
But in fact, the structured cabling system is not only designed to meet the current application requirements of end users, but also can accomplish more. The validity period of a structured cabling system installed between a building and a complex is the same as that of a building; the validity period of a building is several decades. Therefore, the validity period of a structured cabling system should also be calculated as follows. The acceptance of the integrated wiring system should provide a physical layer wired transmission platform for all application protocols that comply with their category that appear within such a long validity period. Note that all the application protocols that comply with the categories mentioned here include not only some of the application protocols that are selected by the end user, it also includes other application protocols that exist and are not selected by end users. In particular, it has not yet appeared, but as long as it is all application protocols that meet the category within the validity period of the cabling system. From this point of view, the so-called "activation and acceptance" only covers a number of application protocols that are selected by the end user, and does not care about other application protocols that exist currently and are not selected by the end user, I did not pay attention to the application protocols that have not yet been generated, but have emerged within the validity period of the cabling system. As a result, the validity period of the structured cabling system has been greatly reduced, the interests of end users are seriously damaged.
Why is the structured cabling system able to cover the application protocols that have emerged within its validity period, especially those that have not yet been produced by most application protocols? Is it amazing to compare it with the decades of building life? Yes! Standard makers of structured cabling systems regulate their categories, such as the familiar five categories, the cat5e category, and the latest six categories. Standards makers of application protocols will use this as the basis for physical layer transmission, to standardize future application protocols, future application protocols will certainly comply with the category of a certain cabling system. In turn, the requirements for the development of application protocols on the physical layer transmission infrastructure are all reflected in the standard advances of structured cabling systems. This is the only reason why we recommend to end users the latest final criteria for the current structured cabling system, Category 6, because it should have lower standards, such as Category 5 and Category 5, covers Application Protocols generated over a longer period of time.
So, how can we ensure that a specific structured cabling system installed on site can cover the application protocols that may appear within its validity period? Very simple. There is only one method, that is, to use a wiring tester to conduct on-site tests on this particular structured cabling system until all 100% pass the category standards it designed, we call it "Test acceptance ". It should be noted that the acceptance is successful for any proportion-based sampling that is fully qualified in the test, or the full inspection is acceptable if there is a small percentage of unqualified sampling, it is not advisable to damage the interests of end users. If strict requirements are met, cabling engineers should be more constrained to eliminate all critical pass data due to the accuracy of the testing instrument through rectification. Error locating and Fault Analysis in on-site rectification are the only way to accumulate rich experience from the engineering site and excellent construction techniques, which cannot be replaced by training and education. Engineers who are easy to pass cat5e acceptance and are not easy to pass cat6 acceptance can almost certainly form a good construction level without long-term strict constraints of acceptance.
It is closely related to the acceptance method to ensure the quality of the structured cabling system after the on-site installation. In a sense, the on-site installation of a structured cabling system that has passed the test and acceptance will exempt the after-sales quality guarantee responsibility, even if there are written constraints in the construction contract, in fact, there will not be any construction party's responsibilities. This is also one of the win-win benefits of strict test acceptance for the end user and the project provider. However, the actual situation is that the project supplier should not only assume the after-sales quality guarantee responsibility in terms of the construction contract, but also stay stuck between 5%-10% after the successful acceptance of the project, even more proportion of "Project Final Payment" is at the end user until the warranty period ends. Sometimes receiving the final payment is a headache for the project owner. It is very human and financial resources that affect the development of new businesses. This reflects the serious end-user self-protection and prevention of common non-strict acceptance, but it makes the excellent engineering companies suffer from injustice. One of the solutions to this problem is to seek the Quality Assurance certificate from the manufacturer directly to the end user. Compared with engineering vendors, manufacturers generally have a large scale, cross-region or even cross-border operation, long-standing, financial stability and solvency, and their quality assurance commitments are more willing to be accepted by end users. Molex enterprise cabling network department launched this concept in the cabling industry for a long time. The warranty period is up to 25 years. The warranty content includes three elements: the quality of products in the system, the system's permanent link or channel performance, and, in particular, all application protocols that meet the requirements during the warranty period ensure that they can run, it is an excellent quality assurance system for on-site structured cabling systems. The end user explicitly obtains written guarantee benefits: free Upgrade is not available yet, as long as all application protocols that meet the category of the Integrated Wiring System within the first 25 years of the validity period of the acceptance of the Integrated Wiring System are generated. The ability to apply for this quality assurance certificate for end users with excellent construction quality is also the best proof for the excellent engineering companies.
The Molex enterprise cabling department has over 20 years of professional integrated cabling system acceptance. The company's cabling network Department produces a wide variety of voice, data, and video transmission products and provides integrated Cabling System Acceptance solutions.
