This Final Draft International Standard is an up to 6 weeks' pre-release of the official publication. It is available for sale during its voting period: 2022-05-06 to 2022-06-17. By purchasing this FDIS now, you will automatically receive, in addition, the final publication.

IEC 63171-4:2022 covers shielded and unshielded free and fixed multimedia connectors (MMC) for data transmission with frequencies up to and above 3 000 MHz for shielded and up to 600 MHz for unshielded connectors, both with current-carrying capacity with up to 8 ways. It specifies the common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well as test specifications, respectively.
The form factor of these connectors allows their use for cable sharing with TOs (Telecommunications Outlet) for structured cabling.
This document covers type 4 connectors. Each part of this series has the associated type number equal to the number of the part in the series. All connectors in the IEC 63171 series are deemed to provide the same functions as defined in IEC 63171, using different mechanical interfaces.
The shielded and unshielded connectors are interoperable for their internal transmission performance and can be exchanged. The shielded version has improved EMC and coupling properties.
The connectors are intended to be used for Single Pair Ethernet (SPE) according, but not restricted to the following IEEE standards: 10Base-T1 (IEEE 802.3cg), 100Base-T1 (IEEE 802.3bw), 1000Base-T1 (IEEE 802.3bp), Multi-Gig Base-T1 (IEEE 802.3ch) and optionally with Power over Data line (PoDL) power supply according to IEEE 802.3bu.
