Multi-channel radio-frequency connectors - Part 4: Sectional specification for type L32-4 and L32-5 circular connectors
Käsitlusala: IEC 63138-4:2025, which is a Sectional Specification (SS), provides information and rules for the preparation of Detail Specifications (DS) for type L32-4 and L32-5 circular connectors with four RF channels and five RF channels, as well as a detailed specification of the blank format.
The L32-4 and L32-5 circular connectors with 50 Ω nominal impedance has four RF channels and five RF channels which can be engaged and disengaged at the same time. They are characterized by threaded coupling mechanisms, anti-misinsertion mechanism, and the operating frequency of each channel is up to 4 GHz. These connectors have been widely used in mobile communication system like TD-SCDMA and TD-LTE and can also be used in some similar equipment.
This document also specifies mating face dimensions for general connectors (grade 2), gauging information and tests selected from IEC 63138-1, applicable to all Detail Specifications relating to type L32 4 and L32-5 circular connectors.
This document cancels and replaces IEC 61169-59:2017.
This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC 61169-59:2017:
a) use of IEC 63138-1:2019 as its generic specification instead of using IEC 61169-1:2013;
b) all the subclauses and test methods are in line with IEC 63138-1:2019;
c) dimension "g" in Table 3, Table 4, Table 7 and Table 8 has been changed from "0,00 min. to 0,8 max." to "1,6 min. to 2,1 max.".

Specification for the testing of balanced and coaxial information technology cabling - Part 2: Cords as specified in ISO/IEC 11801-1 and related standards
Käsitlusala: IEC 61935-2:2021+AMD1:2026 CSV specifies test methods for balanced and coaxial cords, which are used as equipment cords, patch cords, and CP cords, within cabling systems, in accordance with ISO/IEC 11801-1. The test methods and associated requirements are provided to demonstrate performance and reliability and to ensure compatibility of these balanced and coaxial cords during their operational lifetime. This document may also be used for providing test methodology for assessing the performance of other cords.
This fourth edition cancels and replaces the third edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition:
- inclusion of cords up to category 8.1 and category 8.2, as defined in ISO/IEC 11801-1.
