Annotation of standard text IEC 60793-2-ed.9.0 :
IEC 60793-2:2019 contains the general specifications for both multimode and single-mode optical fibres. Sectional specifications for each of the four categories of multimode fibres: A1, A2, A3, and A4 (part of the multimode fibre class A) contain requirements specific to each category. Sectional specifications for each of the three single-mode fibre classes, B, C and D contain requirements common to each class. Each sectional specification includes family specifications (in normative annexes) that contain requirements for the applicable category or sub-categories. These sub-categories are distinguished on the basis of different fibre types or applications. The requirements of this document apply to all classes. Each sectional specification contains the requirements that are common to all the family specifications that are within it. These common requirements are copied to the family specification for ease of reference. Tests or measurement methods are defined for each specified attribute. Where possible, these definitions are by reference to an IEC International Standard (see IEC 60793-1 series) – otherwise the test or measurement method is outlined in the relevant sectional specification. This ninth edition cancels and replaces the eighth edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - introduction of the revised fibre designations for most A1 sub-category fibres and all class B single-mode fibres; - addition of the new fibre model (A1-OM5) defined for A1 category; - addition of class D polarization maintaining fibres. Keywords: specifications for both multimode and single-mode optical fibres LIEC 60793-2:2019 contient les specifications generales applicables a la fois aux fibres optiques unimodales et multimodales. Les specifications intermediaires pour chacune des categories des quatre fibres multimodales: A1, A2, A3 et A4 (parties de la classe de fibres multimodales A) contiennent des exigences specifiques a chaque categorie. Les specifications intermediaires pour chacune des trois classes de fibres unimodales, B, C et D, contiennent des exigences communes a chaque classe. Chaque specification intermediaire inclut des specifications de famille (dans les annexes normatives) qui contiennent des exigences pour la categorie ou les sous-categories applicables. La distinction entre ces differentes sous-categories se fonde sur les differents types de fibres ou les differentes applications. Les exigences du present document sappliquent a toutes les classes. Chaque specification intermediaire contient les exigences qui sont communes a toutes les specifications de famille quelle regroupe. Ces exigences communes sont reprises dans la specification de famille pour quil soit plus facile de sy referer. Les essais ou les methodes de mesure sont definis pour chaque attribut specifie. Dans la mesure du possible, ces definitions se font par reference a une Norme internationale de lIEC (voir serie IEC 60793-1). Si ce nest pas le cas, lessai ou la methode de mesure est indique dans la specification intermediaire correspondante. Cette neuvieme edition annule et remplace la huitieme edition parue en 2015. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - introduction des designations revisees de la plupart des fibres de la sous-categorie A1 et de toutes les fibres unimodales de la classe B; - ajout du nouveau modele de fibre (A1-OM5) defini pour la categorie A1; - ajout des fibres de maintien de la polarisation de classe D. Mots-cles : specifications applicables a la fois aux fibres optiques unimodales et multimodales
