Cable testers
A cable tester is a high-tech tool for installing and servicing computer and telephone networks. A cable tester is useful for professionals and for those who install and maintain network infrastructure themselves. This device allows you to quickly find faults in cable lines and conduct comprehensive network diagnostics.

When choosing a tester, it is important to consider the task and the required functionality. For basic network testing, simple models with basic diagnostic functions are sufficient. Professionals should pay attention to multifunctional devices with advanced measurement and data analysis capabilities.

With this device you can check cable integrity but also locate the wiring as well as find breaks and short circuits. Multifunctional models are equipped with a TDR reflectometer for the precise measurement of cable length and distance to fault.
When choosing a twisted pair cable tester (able to be purchased on this page), you should take a closer look at models with a cross-connection testing function. Such devices allow you to identify incorrect wire connections, crossed pairs, and other installation errors. Modern testers often feature a PoE test function for diagnosing lines with power transmission over twisted pair. It is also easy to find a cable tester with a tracing function – these models are in demand among both amateurs and professionals.
Diagnostic capabilities of modern testers include determining the polarity of wires and testing telephone lines. Many models are equipped with backlit LCD screens for the easy display of measurement results. Professional devices may have a function for storing test results in memory. Many models come with handy bags for safe transportation.
