标准范围

ISO/IEC 14763-4:20 21(E)规定了两对和四对平衡布线的测量a)端到端(E2E)链路类别D、E和EA；b)D类、E类、EA类、F类、FA类以及I类和II类的模块化插头端接链路(MPTL)；c)D类、E类、EA类、F类、FA类以及I类和II类的直接连接电缆。包括在现场和实验室条件下端接两对和四对的自由连接器。这第二版取消并取代了2018年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:？增加了模块化插头终端链路（MPTL）和直接连接电缆的传输性能测量。？介绍了E2E链路测试头设计的附加要求。

ISO/IEC 14763-4:2021 (E) specifies the measurement of two- and four-pair balanced cabling of
a) end-to-end (E2E) link Class D, E and EA;
b) modular plug terminated links (MPTLs) of Class D, E, EA, F, FA and of Class I and II;
c) direct attach cabling of Class D, E, EA, F, FA and of Class I and II.
The free connectors which terminate two and four pairs in field and laboratory conditions are included.
This second edition cancels and replaces the first edition published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
？ measurement of the transmission performance of modular plug terminated link (MPTL) and direct attach cabling were added.
？ Additional requirements of test head designs of E2E link were introduced.
