BS EN 60512-25-9:2008 Connectors for electronic equipment. Tests and measurements. Signal integrity tests. Test 25i. Alien crosstalk

BS EN 60512-25-9 defines a test method which is intended to assess the near-end alien crosstalk (ANEXT) and the far-end alien crosstalk (AFEXT) between connectors in close proximity, when mounted in their mounting systems. Both discrete modular connectors and multi-port panel connectors may be tested using this method.

The method specified in BS EN 60512-25-9 provides a means to test the alien (exogenous) crosstalk between any two ports, as well as a means to assess the overall alien crosstalk from all other ports. This test procedure is generally applicable to any electrical connector, and is particularly suitable to connectors described in BS EN 60603-7 series, BS EN 61076-3-104, and other types of connectors for data transmission.
