This part of IEC 60603 covers 8-way, 12 contacts, shielded, free and fixed connectors, references dimensional, mechanical, electrical and environmental characteristics and tests in IEC 60603-7-7, and specifies electrical transmission requirements, including power sum alien (exogenous) crosstalk, for frequencies up to 2 000 MHz.

These connectors are typically used as “category 8.2” connectors in “class II” cabling systems specified in ISO/IEC TR 11801-9901 and specified in ISO/IEC 11801-11. These connectors are intermateable and interoperable with other IEC 60603-7 series connectors, i.e. as defined in IEC 60603-7-7 and IEC 60603-7-1.

These connectors are backward compatible with other IEC 60603-7 series connectors.

NOTE Transmission performance categories: in this IEC standard, the term “category”, when used in reference to transmission performance, refers to those categories defined by ISO/IEC 11801-1.
