The Softing LinkXpert SQ is a professional cable qualifier and Ethernet tester for copper, fibre optic, and WLAN networks. It is used for commissioning, documentation, and troubleshooting in structured networks, particularly in mixed environments that include both copper and fibre optic lines as well as WLAN connections. The device combines the functions of the LinkXpert series with extended qualification capabilities for higher Ethernet data rates and integrates a WLAN diagnostic function.

Applications

The LinkXpert SQ is used in the installation and maintenance of network infrastructures where precise verification of cable quality and network functions is required. It is suitable for technicians involved in setting up LAN networks, testing cable connections, or troubleshooting existing networks. The integrated WLAN diagnostic function also enables analysis of wireless networks, making it especially useful for projects involving hybrid network environments.

Functions and Equipment in Detail

The device offers comprehensive copper qualification with Ethernet speed tests from 10 Mbit/s to 10 Gbit/s, with tests completed in seconds thanks to 10-Gigabit chip technology. Speed selection can be manual or automatic. For fibre optic links, the LinkXpert SQ enables evaluation of Ethernet applications with data rates of 1, 10, 40, and 100 Gbit/s, based on attenuation and length values according to IEEE 802.3, provided suitable SFP modules are used. Basic copper cable diagnostics include Wiremap, TDR, and length testing, while for fibre optic, an integrated VFL red light source is provided. Optional LWL connector microscopy can also be used.

Technology Explained Simply

The LinkXpert SQ features a 5 1/4 inch TFT touchscreen, enabling intuitive operation. The device measures 160 x 93 x 33 mm and weighs 400 g including the battery. It is powered by a Li-Ion battery (7.2 V / 3.12 Ah), providing a typical runtime of up to 8 hours during Wiremap tests. The power supply supports a voltage of 100–240 V and is equipped with EU, UK, and US plug connectors. The operating temperature range is -10 to 50 °C, and the storage temperature range is -20 to 60 °C. Humidity levels may range from 10 to 80 percent, provided no condensation occurs. The integrated WLAN diagnostics are performed via a USB adapter supporting IEEE 802.11ac, enabling an access point scanner with SSID, BSSID, channel, and encryption. Network diagnostic functions such as DHCP, DNS, Ping, Traceroute, LLDP, CDP, and VLAN are also available. A PoE load test up to Class 8 (90 W) is also integrated.

Compatibility and Accessories

The LinkXpert SQ is compatible with various accessories that extend its functionality. These include Smart Remotes for copper cable testing, multimode and singlemode accessory kits for fibre optic applications, and an installer accessory kit. The use of SFP modules is required to enable fibre optic qualification for higher data rates. The delivery includes a Smart Remote #1, two 50 cm long RJ45 patch cables, a Wi-Fi USB adapter, an LWL adapter (2.5 mm to 1.25 mm ferrule), a quick start guide, and a carrying case.

Installation and Mounting

Installation of the LinkXpert SQ is performed by simply connecting the cables to the appropriate ports on the device. Operation is via the touchscreen, with pre-configured AUTOTESTs available with location and test profiles. Results are displayed as a clear PASS/FAIL evaluation, and a PDF report can be downloaded immediately. Documentation is thus consistent across different projects and teams.

Advantages in Operation

The LinkXpert SQ provides fast and reliable qualification of cables and networks, reducing working time during commissioning and troubleshooting. The integrated WLAN diagnostics and support for PoE load tests extend the functionality, making the device a universal tool for network technicians. The ability to document tests and generate reports supports traceability and quality assurance in projects. The use of pre-configured test profiles ensures standardized testing, which remains consistent even across different teams.
