Anotácia textu normy IEC 60793-2-ed.9.0-RLV :
IEC 60793-2:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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
