IEC 63171-2:20 21涵盖双向、屏蔽或非屏蔽、自由和固定连接器，用于高达600 MHz的数据传输，具有载流能力，称为2型。它分别规定了通用尺寸、机械、电气和传动特性和环境要求以及试验规范。 这些连接器的外形允许它们与已安装的TO共享电缆，用于结构化布线。 在这种情况下，必须评估传输信道的总体性能。 IEC 63171-5中描述了用于密封应用的圆形连接器的可互配和可互操作版本，包括该连接器。 屏蔽和非屏蔽连接器的内部传输性能是可互操作的，并且可以互换。屏蔽版本改善了外来串扰和耦合衰减特性。

IEC 63171-2:2021 covers 2-way, shielded or unshielded, free and fixed connectors for data transmission up to 600 MHz, with current-carrying capacity, known as Type 2. 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 already installed TO’s for structured cabling.
The overall performance of the transmission channel in such case has to be evaluated.
Intermateable and interoperable versions for circular connector for sealed applications including this connector are described in IEC 63171-5.
The shielded and unshielded connectors are interoperable for their internal transmission performance and can be exchanged. The shielded version has improved alien crosstalk and coupling attenuation properties.
