The following guide answers the most important questions about "network testers" and their functions.
The network tester provides you with important information about wiring errors. Network testers can be used to identify, analyze and solve connection problems. Network testers can be used to quickly and easily check whether a wire is continuous, interrupted or short-circuited.
Network testers are used for installation and troubleshooting in telephone, network and low-voltage electrical installations, among other things. These devices can test network cables quickly and easily. Among other things, they can check CAT, COAX and fiber optic cables for wiring errors and malfunctions.
In principle, a network tester helps you (especially for new installations) to check the requirements of the installation. Use cases include cable breaks, short circuits, faults, incorrect assignments or split pairs.
The network tester sends a pulse through the network that is reflected by faulty points.
The integrated display graphically shows the cable status and fault details. Many models also have an easy-to-read color display with backlighting. You can then save the measured value in the network tester's internal memory.
Network testers usually also offer very useful analysis software. You can use this software to evaluate the data on a computer, for example, and then print it out.
The following manufacturers, among others, produce network testers:
With a network tester, you can identify sources of error within your network more quickly, easily and reliably, saving you time and effort while effectively reducing your operating costs and increasing network availability.
It is essential to comprehensively check and document the requirements specified by the customer for the acceptance test. A network tester makes this process easier. At the same time, network testers are a helpful tool for IT support services - errors such as network faults can be detected with network testers, allowing you to reduce downtime and save money.
In general, network testers can be divided into one of 3 categories: Cable Certification Testers, Cable Qualification Testers and Cable Verification Testers.
Cable Qualification Testers are primarily intended for network analysis in existing Ethernet networks.
This type of network tester can be used to determine whether a line achieves the required network speed for Fast Ethernet, Voice over IP or Gigabit Ethernet. Use cases for this scenario are, for example, after a network upgrade or expansion.
You can also use a cable qualification tester to check whether the existing cabling is suitable for a higher transmission speed.
Many devices also allow you to test for length, open circuits, short circuits and reversed pairs. Errors are shown graphically on the tester's display.
A verification tester shows you whether a faulty or disconnected cable is responsible for faults in the network. Applications include switch ports and cable tests.
Cable certification testers help you to check the specifications of network cabling with regard to a norm or standard.
The location and measurement objective are decisive factors when choosing a new network tester. Therefore, these two criteria should be clearly defined BEFORE purchasing the network tester. Among other things, this will determine whether you need a network tester for verification, certification and cable qualification.
Network testers with a high-quality graphical display that clearly and concisely shows you the network errors are significantly more expensive than conventional products. Depending on the application, such a graphical display - depending on the form & variant - can drive up the price.
You should also find out whether you need analysis software. A connection to a PC including a software-driven evaluation supports you in data analysis, processing and documentation.
The price range for network testers is wide. Therefore, you should be 100% sure about the requirements for your new network tester. Our dataTec experts will provide you with manufacturer-independent and non-binding advice when selecting your new measuring device. With this advice, you can put aside any last doubts and buy a network tester that meets your requirements - saving you money, time and nerves.
