Re-embedded test
The re-embedded method enables a more precise and faster test of the signal transmission in RJ45 plug connections than the de-embedded test previously used in the industry. The new test method is described in the IEC 60512-27-100 standard . Manufacturers carry out these tests regularly - especially for new developments such as Cat. 6 A - to prove that plugs and connection modules transmit the signals properly. Among other things, it is checked how interference factors such as so-called crosstalk affect the signal transmission.
The test is also intended to show that the products from one manufacturer also perform as expected when they are combined with products from other manufacturers. Previously, you had to carry out extensive test series and check each connection module with 12 individual test plugs. The high-frequency applications that Cat. 6 A goes, the test setup was prone to errors. With the new re-embedded test, the results are determined purely arithmetically using 14 simulated connectors. Measurements are now made directly on the rigid test head of a network analyzer, so that disturbances can be excluded, which e.g. B. from moving cables. Overall, the re-embedded method leads to a higher measurement quality and more precise statements about the fluctuation and limit value behavior of a connector or connection module.
