IEC 61076-3-104:2017

Overview

IEC 61076-3-104:2017 is an internationally recognized standard developed by the International Electrotechnical Commission (IEC). It specifies product requirements for 8-way, shielded free and fixed connectors used for high-frequency data transmission up to 2,000 MHz. These connectors are essential components within category 7A, class FA cabling systems as outlined in ISO/IEC 11801-1, supporting advanced communications infrastructure. The standard establishes uniform specifications, comprehensive type testing requirements, and preferred values for dimensions and characteristics. Its latest edition incorporates significant clarifications and technical updates in response to evolving technology needs within telecommunications and electronic equipment industries.
