7.5 Transmission characteristics
7.5.1 General
Compliance to this standard in respect to transmission characteristics, is determined
according to specific test methods described in test group EP, see Table 1. The
interoperability of connectors compliant to this standard shall be demonstrated by testing the
fixed connectors with the full range of free connectors according to IEC 60512-28-100.
For the connectors compliant to this standard:
• their interoperability with the IEC 60603-7-7 interface shall be demonstrated by testing the
fixed connectors with the full range of free connectors, according to IEC 60512-28-100,
from 1 MHz to 2 000 MHz.
• their interoperability with the IEC 60603-7-1 interface shall be demonstrated by testing the
fixed connectors with the full range of free connectors, according to IEC 60512-27-100
from 1 MHz to 500 MHz.
Compliance to these transmission performance requirements applies to the separated pairs of
contacts, which are the alternative contacts specified in IEC 60603-7-7, i.e. contact pairs 1-2,
7-8, 3’-6’, 4’-5’. The transmission performance requirements specified herein do not apply to

– 10 – IEC 60603-7-82:2016 © IEC 2016
the non-separated pairs of contacts, which are specified in IEC 60603-7 and IEC 60603-7-1,
i.e. contact pairs 3-6, 4-5. In the case of crosstalk requirements, these apply between the
combinations of separated pairs of contacts.
Compliance to this standard in respect to the alien (exogenous) crosstalk is determined
according to IEC 60512-25-9. Insofar as the connectors according to this standard are
shielded, power sum alien (exogenous) crosstalk requirements of this standard are assumed
to be met, if the requirements for coupling attenuation are met.
All transmission performance requirements apply between the reference planes specified in
IEC 60512-28-100.
In the following subclauses f is the frequency expressed in MHz.
7.5.2 Insertion loss
