Annotation of standard text IEC 60793-1-46-ed.2.0-CMV :
IEC 60793-1-46:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60793-1-46:2024 edition 2.0 and the previous IEC 60793-1-46:2001 edition 1.0. Furthermore, comments from IEC SC 86A experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 60793-1-46:2024 establishes uniform requirements for the monitoring of changes in attenuation, thereby assisting in the inspection of fibres and cables for commercial purposes. This document gives two methods for monitoring the changes in attenuation of optical fibres and cables that occur during mechanical or environmental testing, or both. It provides a monitor in the change of attenuation characteristics arising from optical discontinuity, physical defects and modifications of the attenuation slope: - method A: change in attenuation by transmitted power; - method B: change in attenuation by backscattering. Methods A and B apply to the monitoring of all categories of the following fibres: - class A: multimode fibres; - class B: single-mode fibres; - class C: single-mode intraconnection fibres. Information common to both measurements is contained in Clause 1 to Clause 10, and information pertaining to each individual method appears in Annex A, and Annex B respectively.
