Fibre-optic communication subsystem test procedures - Part 4-1: Installed cabling plant - Multimode attenuation measurement
IEC 61280-4-1: 2019 is applicable to the measurement of attenuation of installed optical fibre cabling plant using multimode optical fibre. This cabling plant can include multimode 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. The test equipment used in this document has one single fibre connector interface or two single fibre connector interfaces. In this document, the optical fibres that are addressed include sub-categories A1-OMx, where x = 2, 3, 4 and 5 (50/125 μm) and A1-OM1 (62,5/125 μm) multimode optical fibres, as specified in IEC 60793-2-10. The attenuation measurements of the other multimode categories can be made using the approaches of this document, but the source conditions for the other categories have not been defined. This third edition cancels and replaces the second edition, published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) changes to Annex F on encircled flux to harmonise with IEC TR 62614-2, but keeping the encircled flux limits defined in Tables F.2 to F.5 unchanged; b) addition of an equipment cord method in Annex D; c) inclusion of testing bend insensitive multimode optical fibre; d) updates to measurement uncertainty; e) definition of additional cabling configurations; f) changes to Table 5 on spectral requirements. Keywords: measurement of attenuation

Procédures d'essai des sous-systèmes de télécommunication fibroniques - Partie 4-1: Installation câblée - Mesure de l'affaiblissement en multimodal
IEC 61280-4-1: 2019 s'applique au mesurage de l'affaiblissement d'une installation câblée en fibre optique utilisant des fibres optiques multimodales. Cette installation câblée peut inclure des fibres multimodales, 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. L'équipement d'essai utilisé dans le présent document possède une ou deux interfaces de connecteur monofibre. Les fibres optiques qui relèvent du présent document comprennent les fibres optiques multimodales des sous-catégories A1-OMx, où x = 2, 3, 4 et 5 (50/125 μm) et A1-OM1 (62,5/125 μm), spécifiées dans l'IEC 60793-2-10. Les mesurages d'affaiblissement des autres catégories multimodales peuvent être réalisés en adoptant les approches du présent document, mais les conditions de la source n'ont pas été définies. Cette troisième édition annule et remplace la deuxième édition parue en 2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) modification de l'Annexe F relative au flux inscrit afin de l'harmoniser par rapport à l'IEC TR 62614-2, mais les limites du flux inscrit définies dans les Tableaux F.2 à F.5 ont été conservées en l'état; b) ajout de la méthode des cordons d'équipement à l'Annexe D; c) ajout d'essais des fibres optiques multimodales insensibles aux courbures; d) mise à jour de l'incertitude de mesure; e) définition de configurations de câblage supplémentaires; g) modifications des exigences spectrales dans le Tableau 5. Mots clés : mesurage de l'affaiblissement
Postopki preskušanja optičnega komunikacijskega podsistema - 4-1. del: Vgrajene žične oblike - Meritev mnogorodovnega slabljenja (IEC 61280-4-1:2019)
Ta del standarda IEC 61280 se uporablja za meritve slabljenja vgrajenega optičnega kabelskega omrežja z večrodovnimi optičnimi vlakni. Ta kabelska inštalacija lahko vključuje večrodovna optična vlakna, konektorje, vmesnike, spojnice in druge pasivne naprave. Kable je mogoče položiti v različnih okoljih, vključno z stanovanjskimi, poslovnimi, industrijskimi prostori in prostori podatkovnih centrov, ter tudi v okoljih zunanjih inštalacij. Preskusna oprema, uporabljena v tem dokumentu, ima en vmesnik konektorjev z enojnim vlaknom ali dva vmesnika konektorjev z enojim vlaknom.
Optična vlakna, ki so obravnavana v tem dokumentu, zajemajo podkategoriji večrodovnih optičnih vlaken A1-OMx, pri čemer je x = 2, 3, 4 in 5 (50/125 μm), ter A1-OM1 (62,5/125 μm), kot je opredeljeno v standardu IEC 60793-2-10. Meritve slabljenja drugih večrodovnih kategorij je mogoče izvesti s pristopi iz tega dokumenta, vendar izvirni pogoji za druge kategorije niso opredeljeni.
