EN IEC 61300-2-33:2026

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.
