IEC 60603-7-81:2015涵盖了8路、屏蔽、自由和固定连接器，参考了IEC 60603-7中的尺寸、机械、电气和环境特性和测试，并规定了频率高达2000 MHz时的电气传输要求，包括功率和外来（外源）串扰。这些连接器通常用作ISO/IEC 11801中规定的“I类”布线系统中的“8.1类”连接器。这些连接器可与IEC 60603-7第2条中定义的其他IEC 60603-7系列连接器进行互配和互操作。这些连接器与其他IEC 60603-7系列连接器向后兼容，但IEC 60603-7-7和IEC 60603-7-71连接器除外。 关键词:连接器、屏蔽、自由和固定连接器

IEC 60603-7-81:2015 Covers 8-way, shielded, free and fixed connectors, references dimensional, mechanical, electrical and environmental characteristics and tests in IEC 60603-7, 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 8.1" connectors in "class I" cabling systems specified in ISO/IEC 11801. These connectors are intermateable and interoperable with other IEC 60603-7 series connectors as defined in Clause 2 of IEC 60603-7. These connectors are backward compatible with other IEC 60603-7 series connectors, except IEC 60603-7-7 and IEC 60603-7-71 connectors. Key words: Connectors, Shielded, Free and Fixed Connectors
