 N EN 60512-29-100

Scope and object

This part of IEC 60512 specifies the test methods for transmission performance for M12-style connectors up to 500 MHz. It is also suitable for testing lower frequency connectors if they meet the requirements of the detail specifications and of this standard.

NOTE 1 All figures show equipment for connectors according to IEC 61076-2-109 as an example.

The test methods provided herein are:

– insertion loss, test 29a;

– return loss, test 29b;

– near-end crosstalk (NEXT) test 29c;

– far-end crosstalk (FEXT), test 29d;

– transverse conversion loss (TCL), test 29f;

– transverse conversion transfer loss (TCTL), test 29g.

For the transfer impedance (ZT) test, see IEC 60512-26-100, test 26e.

For the coupling attenuation see ISO/IEC 11801.

All test methods apply for two and four pair connectors.

NOTE 2 All figures show schemes for four pair cabling and are also suitable for two pair cabling.
