Cable Certification

 Testing a passive network infrastructure, i.e. the outlets, patch panels and keystone modules, is extremely important for a number of very decisive reasons.

As a company, you must be able to rely on the commissioned work having been carried out properly.
The test confirms this to you.

As a contractor, you must protect yourself against later liability and rework. 
The test confirms this to you.

Mistakes happen once a technician has been terminating network outlets for more than 5 hours straight: concentration is lost, or the person is disturbed or distracted while working.

Only a correctly configured test instrument can also deliver correct reports. 

Some installers have their core business in heavy-current engineering and little experience with data cabling. Here the components are almost always not terminated correctly. Only a test brings clarity about the installation.   
Typical faults:
Image 1: Transmission errors caused by improper connection of the cables on the building facade, with more problems in rain or humidity. 
Image 2: The installation cable was laid across the middle of the outlet, so the insulation was cut through by the divider in the middle and a short circuit was created. Twisting and pair shielding are also missing. 
Image 3: Pairs laid far too long into the outlet and twisting no longer present.
Image 4: Short circuit between ground and blue/white can be seen at the top right. The pair shielding was also removed by the installer.
