The TERA Permanent-Link test cable of class FA/Kat. 7A from Softing IT Networks is a specific accessory for performing Permanent-Link tests in the field of network infrastructure. It serves as a replacement or supplement for the test device WX_AD_TERAL (item no. 228005) and enables precise evaluation of installation connections according to the standards for class F/FA. The test cable is designed for use in structured cabling systems, particularly in environments where high data transfer rates and stable signal quality are required.

Applications
This test cable is primarily used in the installation and maintenance of networks where Permanent-Link testing according to class F/FA standards is required. This includes applications in high-speed networks, such as those found in enterprises, data centres, or industrial automation. Class FA/Kat. 7A supports data transfer rates up to 10 Gbit/s over short distances and is suitable for critical applications with high requirements for signal integrity. Thus, the cable is an integral part of quality control in network cabling.

Functions and Features in Detail
The test cable is supplied as a 1-pair set and serves as a reference cable for Permanent-Link testing. It is specifically calibrated to validate the test results of the WX_AD_TERAL device and ensure the accuracy of the test. Using such a cable allows the performance of installed cabling to be evaluated under realistic conditions by capturing actual losses and reflections in the network. The cable’s construction meets the requirements of class FA, ensuring high bandwidth and low signal distortion.

Technology Explained Simply
Class FA/Kat. 7A refers to a cable category designed for frequencies up to 600 MHz, making it suitable for operation in high-speed networks. The term “Permanent-Link” describes a testing methodology in which the performance of a network segment—consisting of two connectors and a cable—is measured under real conditions. The TERA test cable simulates the electrical characteristics of a standard Permanent-Link to calibrate the test device’s measurements. Using such a cable is necessary to ensure that the test devices function correctly and that measured values correspond to actual conditions.

The testing is carried out according to the standards for class F/FA, defined in DIN EN 50173-1 and ISO/IEC 11801. These standards specify the requirements for the electrical and mechanical properties of cabling systems to ensure uniform quality and interoperability. The test cable is therefore a certified tool used in practice to validate network infrastructures.

Compatibility and Accessories
The TERA Permanent-Link test cable is specifically designed for use with the test device WX_AD_TERAL (item no. 228005). It is intended as a replacement or supplement for this device and cannot be combined with other test devices or cable types unless explicitly stated in the device’s documentation. Compatibility is tailored to the specific requirements of the WX_AD_TERAL to ensure accurate measurement and calibration.

Installation and Mounting
Installation of the test cable involves simply plugging it into the corresponding connectors of the WX_AD_TERAL test device. No additional tools or mounting procedures are required. The cable is used as part of the test procedure, integrated into the measurement chain as a reference. Handling is straightforward and does not require special training, provided the test device’s instructions are followed.

Operational Advantages
Using the TERA Permanent-Link test cable ensures high measurement accuracy and reproducibility of results. It reduces the risk of errors during network testing, as it serves as a calibrated reference cable. This is particularly important for certifying network infrastructures, where compliance with standards must be demonstrated. Adhering to class FA/Kat. 7A ensures that testing occurs under the same conditions as real cabling installations, increasing the reliability of the results.
