1 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.
