The Softing IT Networks WX-AD-TERAL2 is a TERA Permanent-Link test adapter, specifically designed for testing network cables of Class F and Class FA, also known as Cat. 7A. This adapter serves as a connecting element between the test device and the cable section to be tested, enabling an accurate and standard-compliant Permanent-Link test. It is available in a pair (two units), allowing measurement across both ends of a cable. The adapter is used in the context of installation and commissioning of structured cabling systems, particularly in high-performance networks requiring high data rates and low latency.

Permanent-Link test is a standardized testing procedure that evaluates the performance of a cable section between two outlets or connection points. The adapter is connected at both ends of the cable under test to measure electrical parameters such as impedance, attenuation, crosstalk, and return loss. This test is performed in accordance with the ISO/IEC 11801 and EN 50173 standards, which define requirements for Category 7A. The adapter thus enables precise evaluation of cable quality under realistic conditions, without affecting the entire network.

Class FA/Cat. 7A refers to the highest performance class for structured cabling systems, designed for frequencies up to 600 MHz. This category supports data transmission rates up to 10 Gbit/s over short distances and is suitable for applications in data centers, high-speed networks, and critical infrastructures. The WX-AD-TERAL2 is specifically developed for these requirements to ensure test accuracy and reliability. The use of an appropriate test adapter is essential to ensure test results are valid and certifiable.

Technology explained simply – The adapter consists of a robust housing with RJ45 connectors equipped with contacts suitable for Category 7A. The construction ensures a secure and stable connection, preventing measurement errors caused by loose contacts or contact wear. The use of TERA technology (Test Equipment Reference Architecture) provides a standardized interface, ensuring compatibility with various test devices. The adapters are designed to not distort the electrical characteristics of the cable, ensuring the measurement is as undistorted as possible.

Compatibility and accessories – The WX-AD-TERAL2 is designed for use with test devices supporting the TERA interface. It is specifically designed for testing cables of Class FA/Cat. 7A and cannot be used for lower categories, as the electrical requirements would not be met. The exact selection of the test cable depends on the test device platform used and should comply with the requirements of the respective standard.

Mounting and installation – Installation is performed by simply plugging the adapter into the RJ45 socket at the end of the cable to be tested. One adapter is installed at each end of the cable, creating a complete test connection. The installation requires no tools and can be quickly performed by skilled personnel. The connection must be secure and clean to avoid measurement errors. The test is then carried out using a suitable test device communicating with the adapters via the TERA interface.

Advantages in operation – Using the WX-AD-TERAL2 enables fast and reliable testing of Class FA/Cat. 7A cables. The standardized interface ensures high compatibility with various test devices, standardizing testing processes. Precise measurement supports quality assurance during installation of high-performance networks and ensures cables meet required performance specifications. The robust construction of the adapter ensures long service life and reliable results over multiple testing cycles.
