1 Scope and purpose

The test method specified in this part of GB/T 5095 is used to assess the proximity between the connectors installed in its installation system.

End Alien Crosstalk (ANEXT) and Far End Alien Crosstalk (AFEXT). Both modular connectors and multi-port panel connectors can be used

Method to conduct experiments. This method provides a way to test for alien (foreign) crosstalk between any two ports, and to assess the

All alien crosstalk at the mouth. This test procedure is widely applicable to all electrical connectors in electromechanical components, especially to the IEC 60603-7 series

Columns and connectors described in IEC 61076-3-104, as well as other types of connectors used for data transmission.
