Anotation

IEC 61300-2-33:2026 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61300-2-33:2026 edition 4.0 and the previous IEC 61300-2-33:2012 edition 3.0. Furthermore, comments from IEC TC SC 86B experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 61300-2-33:2026 evaluates the behaviour of a fibre optic mechanical splice, a fibre management system, a protective housing or a hardened connector after being subjected to a specified number of assembly and disassembly operations. The test procedures described in this document simulate conditions that the component can encounter during its service lifetime to check the following performance characteristics: - capability of an optical mechanical splice to be reinstalled after being disassembled; - capability to reintroduce fibre management systems and protective housings, accessing fibres and optical components and making reconfigurations without disturbing transmission in adjacent fibre circuits; - sealing performance of the protective housing after frequent opening and closing operations; - sealing performance of the hardened connector after frequent mating and demating operations. This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of the terms and definitions according to IEC 61753-1:2018 and IEC 61756-1:2019; b) update of the test severities according to the new edition of IEC 61753-1:2018; c) addition of procedure D to verify the sealing performance after frequent mating and demating of a hardened connector.
