10 Best Network Cable Testers 2025 in the UK

The FLUKE Networks LinkIQ Cable+Network Tester, LIQ-100, is a versatile tool designed for comprehensive cable performance testing. It supports up to 10GBASE-T, making it compatible with high-speed network cables. Testing functions are extensive, offering capabilities such as nearest switch diagnostics, PoE verification, and detailed cable metrics like length and wire map. This makes it highly suitable for network professionals who need precise and varied testing options.

The display provides clear information on cable performance, network diagnostics, and power over Ethernet (PoE), which is beneficial for quick troubleshooting and verification tasks. However, the weight of the device is 1.54 kg, which might impact portability, especially for field technicians who need to carry multiple tools. The compact design helps alleviate this to some extent, but it is still relatively heavier compared to some other network testers.

Ease of use is enhanced by the straightforward display and included battery, ensuring the device is ready to use out-of-the-box. The tester is battery-powered, using lithium-ion batteries, which offer good longevity but might require regular recharging depending on usage intensity. With a customer rating of 4.5 out of 5 stars, users generally find it reliable and effective. In summary, the FLUKE Networks LinkIQ Cable+Network Tester is a robust choice for thorough cable and network testing, particularly suited for environments where detailed diagnostics and high-speed cable compatibility are essential, though its weight may be a consideration for frequent portable use.

The TREND Networks SignalTEK NT is a versatile network cable tester designed for both copper and fibre cables, making it suitable for a wide range of network environments. It tests network traffic performance to IEEE802.3ab standards and includes wiremap testing to identify issues such as opens, shorts, miswires, and split pairs. This makes it effective for troubleshooting various network cabling issues.

With its ability to diagnose parameters like PoE/PoE+ load, port ID, port speed, and network configurations, it provides comprehensive diagnostics for network technicians and data installers. The touchscreen display adds to its ease of use, offering straightforward operation with the touch of an autotest button for quick diagnostics. Additionally, the device generates real-time PDF reports that users can download and share via a memory stick or the AnyWARE App, making documentation and reporting more seamless.

Weighing only 183 grams, the SignalTEK NT is highly portable, which is an advantage for technicians who need to carry it around different job sites. However, its niche functionality and relatively high price might not be justified for casual users or smaller projects. The TREND Networks SignalTEK NT is a powerful tool for professional network technicians and data installers who require a reliable and comprehensive testing solution.

The FLUKE networks LinkIQ Advanced Kit is designed for those who need comprehensive testing of network cables, and it excels in several aspects of cable testing. It supports high-performance testing for cables up to 10GBASE-T using frequency-based measurements, which is ideal for modern high-speed networks. For network diagnostics, it provides the ability to detect and diagnose cables connected to switches, offering details like the switch name, port number, and VLAN information, making it useful for network administrators who require detailed insights. The kit also includes PoE Verification, which can detect the PoE class and power, and perform a load test, ensuring that the power over Ethernet is effectively utilized and meets the required standards. A notable inclusion is the IntelliTone Probe which assists in locating cables, adding convenience to cable management and troubleshooting tasks.

On the downside, the FLUKE networks LinkIQ Advanced Kit is relatively heavy, weighing 4.87 pounds, which may not be ideal for users who need to carry it around frequently. The product is battery-powered and includes a lithium-ion battery, meaning you will need to manage battery life, though batteries are included, which is a convenience. The product ranks well in network testers but is less popular in the broader DIY & Tools category, hinting it may be more suited to professional use than casual or hobbyist users.

This kit is particularly beneficial for network professionals who need advanced cable testing and diagnostics features, while its weight and battery reliance might be slightly inconvenient for frequent portability. Its user-friendly features, such as PoE verification and IntelliTone Probe, make it a strong choice for those in need of robust network cable testing solutions.
