Annotation of standard text IEC 61756-1-ed.2.0 :
IEC 61756-1:2019 covers general information on fibre management system interfaces. It includes the definitions and rules under which a fibre management system interface is created and it provides also criteria to identify the minimum bending radius for stored fibres. This document allows both single-mode and multimode fibre to be used. Liquid, gas or dust sealing requirements at the cable entry area or cable element ending are not covered in this document. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - addition of figures to show the interface between protective housing and fibre management system; - addition of definitions for protective housing, closure, wall box, street cabinets and optical distribution frame modules; - addition of table with dimensions of fusion splice protectors and mechanical splices; - addition of method to identify the minimum bending radius for stored fibres; - addition of clause for other factors relevant to fibre management systems; - addition of annex A for example of calculating the minimum bending radius of stored fibres in a fibre management system. Keywords: fibre management system interfaces, minimum bending radius for stored fibres IEC 61767-1:2019 englobe des informations generales sur les interfaces de systeme de gestion des fibres. Elle comprend les definitions et les regles regissant la creation dune interface de systeme de gestion des fibres et elle fournit des criteres permettant didentifier le rayon de courbure minimal des fibres stockees. Le present document permet dutiliser les fibres unimodales et les fibres multimodales. Les exigences relatives a letancheite aux liquides, aux gaz ou a la poussiere au niveau de la zone dentree de cable ou a lextremite des elements de cable ne sont pas couvertes par le present document. Cette deuxieme edition annule et remplace la premiere edition parue en 2006 dont elle constitue une revision technique. La presente edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - ajout de figures de representation de linterface entre une enveloppe de protection et le systeme de gestion des fibres; - ajout des definitions denveloppe de protection, de boitier, de boite murale, darmoire situee dans un environnement urbain et de module repartiteur optique; - ajout dun tableau qui donne les dimensions des protecteurs depissures par fusion et des epissures mecaniques; - ajout dune methode permettant didentifier le rayon de courbure minimal des fibres stockees; - ajout dun article portant sur dautres facteurs applicables aux systemes de gestion des fibres; - ajout de lAnnexe A qui donne un exemple de calcul du rayon de courbure minimal des fibres stockees dans un systeme de gestion des fibres. Mots cles : interfaces de systeme de gestion des fibres, rayon de courbure minimal des fibres stockees
