Qualification is a new category of testers designed to meet the emerging needs of network technicians who need to upgrade to higher network speeds as well as troubleshoot connectivity problems. Qualification testers, like Fluke Networks new CableIQ Qualification Tester, determines if an existing cabling link can or can not support certain network speeds and technologies. This differs from certification testers, like the DTX CableAnalyzer, which guarantees cabling installations comply with TIA/ISO performance standards and basic verification testers, like the MicroScanner Pro, which tests if the cable is connected correctly.
Qualification testers allow network technicians to perform a series of troubleshooting steps to better isolate cabling from network problems. For example, a first step in troubleshooting a network connectivity problem might be to check the speed and duplex settings of connected devices. If the tester shows the settings are matched, but the problem persists, a qualification test can be performed. Performing a qualification test will allow the technician to identify whether insufficient cabling bandwidth is the cause of the problem. Knowing your cabling's bandwidth capability allows you to close trouble tickets faster and helps ensure seamless upgrades to higher network speeds.
Choosing the right tool for the job
When to use a qualification tester: If you are a network technician, and need to see whether the existing cabling will support your 1000BASE-T network, a qualification tool is the right choice. If you need to troubleshoot connectivity problems and isolate cabling problems from network problems, then qualification is the perfect solution. If you have an existing network and are doing small adds, moves, and changes, or are setting up a temporary network and just need to qualify it for a specific network technology, a qualification tool is a good option.
When to use a certification tester: If you're a commercial installer or network owner who needs to prove that all cabling has been installed correctly, and meets TIA or ISO link specifications, you must certify it. If you are in a troubleshooting environment, and need to show unequivocally that the link under test is failing category 5e or 6 performance requirements according to TIA or ISO standards, your only choice is a certification tool. If you have a mixture of fiber and copper cabling, and often need to test both, certification tools do that best.
To receive the support and financial security of a manufacturer's warranty, certification to TIA/ISO standards is your only option. Anything else makes the installer liable for the performance of the installation which can be quite costly. For example, a large 1000 link installation could represent a $100,000 (USD) project, which can be a hefty liability if manufacturer warranty is not obtained.
When to use a verification tool: Verification tools are typically used by any technician who pulls and terminates cable or performs basic moves, adds and changes. These tools are used as a first line of defense in finding connection and wire-pairing faults.
