General
Class	EA

The RJ45 Permanent-Link test adapter set of class EA/Cat. 6A from Softing IT Networks is a specific accessory for the installation and testing of network cabling systems in the field of structured cabling. It enables precise measurement of cable parameters under realistic conditions by establishing the connection between the cable section to be tested and the test device. The set is designed for use in networks with data transmission rates up to 10 Gbit/s and complies with the requirements of Category 6A, also known as class EA. This category is relevant for high-speed applications in modern office and corporate networks.

Permanent-Link test adapter set
The set consists of two components: a pair of class EA Permanent-Link interface adapters and a pair of pre-assembled class EA Permanent-Link test cables. The interface adapters are specifically designed for connection with RJ45 connectors and enable precise measurement by accurately representing the physical and electrical characteristics of the cable under test under realistic conditions. The test cables are also designed to meet the requirements of class EA and serve as a reference connection between the test device and the cable section under test.

Applications
The test adapter set is primarily used in the field of network infrastructure, particularly for the installation, maintenance, and certification of structured cabling systems. It is suitable for testing cable sections in office buildings, server rooms, data centers, and other environments where high data transmission quality is required. The set is used in conjunction with professional network test instruments that measure parameters such as insertion loss, impedance, crosstalk, and attenuation.

Functions and equipment in detail
The interface adapters are designed as RJ45 plugs and serve as the physical interface between the cable under test and the test device. They are constructed to transmit the electrical characteristics of the cable as unchanged as possible to ensure accurate measurement. The test cables are also designed as RJ45 plugs and connect the test instruments to the adapters. The assembly is carried out according to the standards of class EA, ensuring uniform length and defined impedance.

Technology explained simply
A Permanent-Link test simulates the actual conditions of an installed cabling system by establishing a connection between two RJ45 sockets via the cable under test. The test adapters and cables provide the necessary connections required for accurate measurement. Class EA corresponds to Category 6A, designed for frequencies up to 500 MHz and supporting a maximum data rate of 10 Gbit/s. The measurement is performed considering the actual installation conditions, making the results relevant for certification of cabling according to international standards such as ISO/IEC 11801 or TIA/EIA-568.

Compatibility and accessories
The set is designed for use with network test instruments that support Permanent-Link testing. It is specifically designed for testing cables of Category 6A and cannot be used for lower categories such as Cat. 5e or Cat. 6, as the electrical requirements are not met. Compatibility is limited to the specific requirements of class EA.

Installation and mounting
Installation is performed by simply inserting the interface adapters into the RJ45 sockets at both ends of the cable to be tested. The test cables connect the adapters to the test device. The installation requires no special tools or additional components. The connection must be secure and clean to avoid measurement errors. The set is used in conjunction with a suitable network test instrument that supports the Permanent-Link function.

Advantages in operation
The use of the Permanent-Link test adapter set ensures precise and reproducible measurement of cable parameters. The results comply with standard requirements and enable reliable certification of the cabling. The pre-assembly of the test cables and standardization of the adapters ensure a uniform measurement method that is reproducible across different projects and environments. The measurement is performed under realistic conditions, increasing the reliability of the results.
