    Network Testers

    Network Testers are devices designed to measure and test existing LAN connections. LAN Testers are a must-have piece of equipment for every network installer. Whether you are troubleshooting an existing connection or installing brand new cable connections, cable testers check the signal quality and point at exact cables or cores that need attention resulting in enhanced productivity and customer satisfaction. They can also be used for certifying connections. Network cable testers can be used with copper or fibre cabling.

    How Do Network Testers Work?

    A network cable tester is an electronic device that measures the conductive between two ends of a cable. It also checks and measures signals for correct wiring. There are two most common ways of testing the connection:

    • Tester sends a current down the wire and measures its level. This is called continuity testing.Tester sends a current and a voltage down the connection. Resistance testing is measuring a voltage and current, it calculates a resistance.

    What is a Typical Application of Network Cable Testers?

    For different data that can be transmitted over the Ethernet network data cables. Testers are suitable for testing computer Cat 3C, Cat5, Cat5e, Cat6, Cat6a, Cat6e, Cat 7 cables. They can also be used for testing and confirming the correct installation of telephone lines, all kinds of RJ45 fitted cables, LAN cables, and some models even coaxial cables. Network testers can be found in areas such as:

    • Network security
    • Network upgrades and expansions
    • Network maintenance and monitoring

    What Brand Manufactures the Best and Most Accurate Testers?

    The market leading brands such as Fluke Networks or Ideal Networks specialise in producing high-end Network Cable testers. These devices are very accurate but may be very expensive. For many installers or DIY enthusiasts, basic or less-expensive models from our range would be an ideal choice.

    Network testers have become essential tools for businesses and IT professionals who rely on seamless network connectivity. With their comprehensive assessment capabilities, troubleshooting features, and compatibility across different network types, these testers streamline network maintenance, ensure optimal performance, and contribute to a robust and reliable network infrastructure. By investing in network cable testers, organisations can proactively address network issues, reduce downtime, and deliver enhanced connectivity experiences to their users.

    Industrial Application of Network Cable Testers

    Network cable testers are an indispensable part of a comprehensive tool kit to ensure reliable and efficient data transmission in various industrial settings. They help diagnose and troubleshoot issues, ensuring optimal network performance and minimising downtime.


    In the realm of cybersecurity, network cable testers are crucial for identifying potential vulnerabilities in physical infrastructure. By testing cable integrity and identifying unauthorised connections, these tools help protect sensitive data from unauthorised access and ensure the overall security of the network. Using an RJ45 ethernet cable speed tester or network cable speed tester can help pinpoint and isolate potential vulnerabilities.

    IT network

    LAN testers are essential for maintaining the smooth operation of IT networks. By verifying cable performance and identifying faults like shorts, opens, or miswires, RJ45 RJ11 network cable tester tools help prevent network outages and ensure uninterrupted flow of data.

    Data storage centres

    In data storage centres, where massive amounts of data are stored and transmitted, network cable testers are critical for ensuring reliable and high-speed connections. These tools help identify and troubleshoot cable issues that could lead to data loss or corruption. In Malaysia, many companies buy security network testers to ensure their data storage centres are running at optimal levels.

    Frequently Asked Questions About Network Cable Speed Testers

    Why do we need to test computer network cables?

    Testing network cables with cable testers network is crucial for ensuring the reliable and efficient operation of IT infrastructure. Faulty or damaged cables can lead to network downtime, slow speeds, and data loss. Regular testing with an ethernet cable speed tester helps identify and rectify these issues, maintaining optimal network performance.

    How do I test my network cable with a tester?

    To test a network cable, connect one end to the main unit of the LAN tester and the other end to the remote unit. The tester will then send signals through the cable and check for continuity, shorts, opens, and other issues. Some advanced testers, like a RJ45 line tester, can even measure cable length and identify the location of faults.

    What is the difference between a network cable tester and an ethernet network tester?

    The terms network cable tester and ethernet network tester are often used interchangeably. However, technically, an ethernet network tester is a specific type of network cable tester such as RJ45 cables, while a network cable tester can be used to test a wider range of cables, including coaxial and telephone cables.

    What is the advantage of a cable tester?

    There are many advantages to using a network or ethernet cable speed tester. They are:

    • Quickly identifying and diagnosing cable faults.
    • Preventing network downtime and ensuring uninterrupted data flow.
    • Optimising network performance and speed.
    • Saving time and money by avoiding costly repairs or replacements.
    • Ensuring compliance with industry standards and regulations.
