Fibre optic interconnecting devices and passive components - Performance standard - Part 031-3: Non-connectorized single-mode 1×N and 2×N non-wavelength-selective branching devices for Category U - Uncontrolled environment

IEC 61753-031-2:2014(E) contains the minimum initial tests and measurement requirements and severities which a non-wavelength selective branching device (NWBD) should satisfy in order to be categorized as meeting the requirement of this IEC standard. The requirements cover balanced bidirectional non-connectorized single-mode 1xN and 2xN non wavelength-selective branching devices for use in an IEC Category C environment (N is the number of branching ports), especially but not exclusively used for PON application. For balanced NWBD two attenuation and uniformity performance classes are considered: - class A (premium class) which meets more restrictive requirements (i.e. for extended reach PON application) and - class B (standard class) for standard application (i.e. normal reach PON application). The requirements also cover unbalanced bidirectional non-connectorized single-mode, non-wavelength-selective branching devices; however, the specifications of unbalanced branching devices are limited to 1x2 and 2x2 devices because they are the most commonly used. Keywords: non-wavelength selective branching device (NWBD), IEC Category C environment

Dispositifs d'interconnexion et composants passifs à fibres optiques - Norme de performance - Partie 031-3: Dispositifs de couplage indépendants de la longueur d’onde 1xN et 2xN en unimodal, non-connectorisés, pour catégorie U - Environnement non contrôlé

L'IEC 61753-031-3:2014 contient les exigences et les sévérités initiales minimales d'essais et de mesures auxquelles il convient qu'un dispositif de couplage indépendant de la longueur d'onde (NWBD) satisfasse afin d'être classé comme conforme à la présente norme. Ces exigences couvrent les dispositifs de couplage 1xN et 2xN en unimodal, non connectorisés, bidirectionnels symétriques destinés à être utilisés dans un environnement de catégorie U selon l'IEC (N correspond au nombre de ports de connexion), utilisés en particulier, mais pas de manière exclusive, pour les applications PON. Dans le cas des NWBD symétriques, deux classes d'affaiblissement et d'uniformité sont prises en compte: - La classe A (classe de première qualité) qui satisfait aux exigences les plus restrictives (à savoir pour les applications PON étendues) et - la classe B (classe normale) pour les applications normales (à savoir par exemple les applications PON d'étendue normale). Ces exigences couvrent aussi les dispositifs de couplage indépendants de la longueur d'onde en unimodal non-connectorisés bidirectionnels asymétriques; toutefois les spécifications des dispositifs de couplage asymétriques sont limitées aux dispositifs 1 x 2 et 2 x 2 car ce sont eux qui sont les plus couramment utilisés. Cette deuxième édition de l'IEC 61753-031-3 annule et remplace la première édition parue en 2009 et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - domaine d'application mis à jour et étendu pour rendre compte de l'introduction de deux classes de performances d'affaiblissement et d'uniformité pour les NWBD symétriques à la place des technologies des dispositifs de couplage du marché; - liste des références normatives mise à jour; - introduction simplifiée aux deux types de bandes spectrales; - Article 5, Exigences de performances, mis à jour et étendu pour rendre compte de l'introduction de deux classes de performances d'affaiblissement et d'uniformité pour les NWBD symétriques; - simplification des essais pour exclure les essais de chaleur humide (état continu) et de chocs pour les exigences de performances; - modification de l'Annexe A pour introduire les exigences calculées et minimales pour l'affaiblissement et l'uniformité; - mise à jour de l'Annexe B pour rendre compte de la révision des exigences de performances. Mots clés: dispositif de couplage indépendant de la longueur d'onde (NWBD), environnement de catégorie U de l'IEC

Optični spojni elementi in pasivne komponente - Tehnični standard - 031-3. del: Enorodni 1xN in 2xN nevalovno dolžinski selektivni optični sklopniki brez konektorjev za kategorijo U - Nenadzorovano okolje (IEC 61753-031-3:2014)

Ta del standarda IEC 61753 zajema najmanjše začetne zahteve in stopnje zahtevnosti za preskuse in meritve, ki jih mora izpolnjevati valovnodolžinsko neodvisni selektivni razvejilni element (NWBD), da ustreza zahtevam tega standarda.
Zahteve zajemajo uravnotežene dvosmerne enorodne valovnodolžinsko neodvisne selektivne razvejilne elemente 1 × N in
2 × N brez konektorjev za uporabo v okolju kategorije IEC U
(N je število razvejilnih vrat), ki se še posebej uporabljajo za PON, vendar ne izključno.
Za uravnotežene nevalovno dolžinske selektivne optične sklopnike sta obravnavana dva kakovostna razreda slabljenja in enotnosti:
razred A (premium razred), ki izpolnjuje strožje zahteve (tj. PON
z razširjenim dosegom), in razred B (standardni razred) za standardno uporabo (tj. PON
z običajnim dosegom).
Zahteve zajemajo tudi neuravnotežene dvosmerne enorodne nevalovno dolžinske
selektivne optične sklopnike; vendar so specifikacije neuravnoteženih optičnih
sklopnikov omejene na naprave 1 × 2 in 2 × 2, ker se uporabljajo najpogosteje.
