Annotation of standard text IEC 61746-1-ed.1.0 :
IEC 61746-1: 2009 provides procedures for calibrating single-mode optical time domain reflectometers (OTDR). It only covers OTDR measurement errors and uncertainties. This standard does not cover correction of the OTDR response. This first edition of IEC 61746-1 cancels and replaces the second edition of IEC 61746, published in 2005. It constitutes a technical revision. The main technical changes are the adaptation of Clause 4, the suppression of Clause 10, the improvement and the addition of some definitions, the change of some calculations and the change of graphical symbology to IEC/TR 61930. Keywords: calibrating single-mode optical time domain reflectometers (OTDR) LIEC 61746-1:2009 fournit des procedures destinees a letalonnage des reflectometres optiques dans le domaine de temps pour fibres unimodales (OTDR). Elle ne traite que des erreurs de mesure et incertitudes de lOTDR. Cette norme ne couvre pas la correction de la reponse de lOTDR. Cette premiere edition de la CEI 61746-1 annule et remplace la deuxieme edition de la CEI 61746, publiee en 2005. Elle constitue une revision technique. Les principales modifications techniques sont ladaptation de larticle 4, la suppression de larticle 10, lamelioration et lajout de certaines definitions, le changement de certains calculs et le changement de symbologie graphique IEC / TR 61930.
