Fibre-optic communication subsystem test procedures - Part 4-2: Installed cabling plant - Single-mode attenuation and optical return loss measurements

Edition date: 2024-05-06
In Force
Available languages: English, French
Summary: IEC 62180-4-2:2024 is applicable to the measurements of attenuation and optical return loss of an installed optical fibre cabling plant using single-mode fibre. This cabling plant can include single-mode optical fibres, connectors, adapters, splices, and other passive devices. The cabling can be installed in a variety of environments including residential, commercial, industrial and data centre premises, as well as outside plant environments. This document is applicable to all single-mode fibre types including those designated by IEC 60793-2-50 as Class B fibres. The principles of this document can be applied to cabling plants containing branching devices (splitters) and at specific wavelength ranges in situations where passive wavelength selective components are deployed, such as WDM, CWDM and DWDM devices. This document is not intended to apply to cabling plants that include active devices such as fibre amplifiers or dynamic channel equalizers. This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) addition of the equipment cord method;
b) addition of test limit adjustment related to test cord grades;
c) refinements on measurement uncertainties.

L'IEC 61280-4-2:2024 s’applique aux mesures de l’affaiblissement et de l’affaiblissement de réflexion optique d’une installation câblée à fibres optiques utilisant des fibres unimodales. Cette installation câblée peut inclure des fibres optiques unimodales, des connecteurs, des adaptateurs, des épissures et d’autres dispositifs passifs. Le câblage peut être installé dans une diversité d’environnements, notamment dans des locaux résidentiels, commerciaux ou industriels et des centres de traitement de données, ainsi que dans des environnements d’installations extérieures. Le présent document s’applique à tous les types de fibres unimodales, y compris celles désignées comme des fibres de Classe B par l’IEC 60793-2-50. Les principes du présent document peuvent s’appliquer aux installations câblées contenant des dispositifs de commutation (répartiteurs) et sur des plages de longueurs d’onde spécifiques, dans des situations dans lesquelles sont déployés des composants passifs sélectifs en longueurs d’onde, par exemple des dispositifs WDM, CWDM et DWDM. Le présent document n’est pas destiné à s’appliquer à des installations câblées qui incluent des dispositifs actifs tels que des amplificateurs à fibres ou des égaliseurs de canaux de transmission dynamiques. Cette troisième édition annule et remplace la deuxième édition parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) ajout de la méthode des cordons d’équipement;
b) ajout de l’ajustement de limite d’essai lié aux classes de cordons d’essai;
c) affinements des incertitudes de mesure.
