IEC 61076-3-104:2017（E）为频率高达2 000 MHz的数据传输建立了8路屏蔽自由和固定连接器的统一规范和型式测试要求，并在ISO/IEC 11801-1中规定的FA类布线系统中用作7A类连接器。它包含所有测试方法和序列、严重性以及尺寸和特性的首选值。 IEC 61076-3-104的第三版取消并取代了2006年发布的第二版，构成了技术修订。 与上一版相比，此版本包括以下重大技术变更: -标题已更改，纳入频率高达2 000兆赫的传输； -某些样式的图纸已被更正以供澄清； -图23和24已经更新；-图3已被更新以包括参考尺寸和尺寸格式变化； -图7的尺寸已经更新； -为了与最新的截面规范保持一致，已删除了型号名称和订购信息； -更新了测试时间表，以包括适当的IEC 60512测试编号； -对2 GHz级别的电气性能要求进行了修订，并增加了性能类别的互换性信息。

IEC 61076-3-104:2017(E) establishes uniform specifications, type testing requirements for 8 way, shielded free and fixed connectors for data transmissions with frequencies up to 2 000 MHz, and used as category 7A connectors in class FA cabling systems specified in ISO/IEC 11801-1. It contains all test methods and sequences, severity and preferred values for dimensions and characteristics.
This third edition of IEC 61076-3-104 cancels and replaces the second edition, published in 2006, and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- the title has been changed to incorporate transmissions with frequencies up to 2 000 MHz;
- the drawings of some styles have been corrected for clarification;
- Figures 23 and 24 have been updated;
- Figure 3 has been updated to include reference dimensions and dimensional format changes;
- the dimensions of Figure 7 have been updated;
- the type designation and ordering information has been removed for consistency with the most updated sectional specification;
- the test schedule was updated to include appropriate IEC 60512 Test Nos;
- the electrical performance requirements have been revised for 2 GHz level and interchangeability information has been added for performance categories.
