The process is increasingly complex, as new systems are implemented or old ones are modified. Therefore, this task must be carried out by trained personnel, that is, certified technicians who are aware of the new verification parameters.
Thanks to the work of professionals, it is possible to determine what problems are in structured cabling and fix them as quickly as possible, so that they return to adequate performance.
A specialized technician will be in charge of verifying that the entire installation is correct. For this reason, when the wiring links are passed, they should give "pass" as a result. If this does not happen, it means that the installation has not been optimal and that it should be reviewed.
The review makes it possible to identify which links are failing in order to correct them and recheck their operation. If we have to simplify the steps of the certification process, we could say that they are reduced.
As a result of the comparison, it is possible to know if the system that has been installed has the connectivity and the operation that it should. The structured cabling certification process is necessary in order to obtain the guarantee of the person in charge of its manufacture. In other words, they will be able to fulfill the role for which they were designed.
What is the structured cabling certification process?
In the certification process, what is sought is to make a comparison between the transmission performance of the system that has just been installed with a standard. For this, a pre-established method is used, according to each system
When the cabling for a system is done, the job doesn't end here. This is because after installation it is necessary to certify the quality of the wiring, in other words, to validate that it is working as it should. But how do you go about the structured cabling certification process ? Here we tell you more!
Only a certification tester can answer this question. Used by commercial installers and corporate service managers to ensure new wiring fully meets the wiring requirements of standards such as Category 6A or 2nd Edition Class EA, certification is the most rigorous cable test. It is also required by cabling manufacturers to benefit from a warranty.
Certification includes all of the tests that are performed during verification and qualification, but also allows multiple measurements to be performed across predefined frequency ranges and to compare detailed results to standards set by TIA bodies or ISO. The results determine compliance with the standard and indicate whether a link conforms to a specific wiring category such as Category . This tells you which application the cabling is capable of supporting.
Qualification testers, which combine verification features, are also great troubleshooting tools. They are ideal for small additions, moves and modifications, or for setting up a temporary network that must be qualified against a specific network technology. They can also help when making a decision as to whether an existing cabling installation needs to be upgraded to support a new application. But just like verification testing, qualification does not provide the certification required by cabling manufacturers.

Qualification tests include a functional check, but are more sophisticated and have cabling bandwidth qualification capabilities. The qualification provides the information necessary to determine whether the wiring under test will be able to support the signals for specific applications. For example, if you have two cables that are validated by verification tests, a qualifying tester might also show that only one of the cables is capable of supporting.
For fiber optics, a simple visual fault locator (VFL) can serve as a verification tool, as it checks the continuity of a fiber optic connection to help locate breaks, connectors, and splices. It also makes it possible to verify the correct polarity and orientation of optical fibers within multi-fiber connectors.
While checking is great for troubleshooting and is really the first line of defense in finding wiring problems, more extensive wiring testing requires more than just checking. Therefore, it is rarely the only method used, unless you are testing voice-only POTS (Ordinary Telephone Service) applications running over simple telephone grade cables such as Category 3.
Verification tests will therefore not be sufficient to verify the ability of the cabling to support specific applications. Nor will they be sufficient to ensure compliance with the standards required to obtain a manufacturer's warranty.
First of all, is the wiring properly connected? Verification tests answer this question. For cabling copper links, these easy-to-use, inexpensive tools perform basic continuity checking functions such as drawing up the wiring diagram and generating tones. The wiring diagram will tell you that each pair is connected to the correct pins at the male and female jacks and that the contacts at the terminations are adequate, while tone generation is used to help identify a specific cable in a beam or at the far end.
Some verification testers include Time Domain Reflectometry (TDR) functionality to help determine the distance to the end of a cable or a problem point. It can also detect whether a switch is connected to the cable being tested.
