Calibration of optical time-domain reflectometers (OTDR)

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.

Kalibirerung optischer Rückstreumessgeräte (OTDR)

Etalonnage des réflectomètres optiques dans le domaine de temps (OTDR)

Fournit des procédures destinées à l'étalonnage des réflectomètres optiques dans le domaine de temps pour fibres unimodales (OTDR). Elle ne traite que des erreurs de mesure et incertitudes de l'OTDR. Cette norme ne couvre pas la correction de la réponse de l'OTDR

Foreword
The text of document 86/230/FDIS, future edition 2 of IEC 61746, prepared by IEC TC 86, Fibre
optics, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 61746 on 2005-02-01.
This European Standard supersedes EN 61746:2001.
Specific changes to EN 61746:2001 include the development of Clause 9, “Reflectance calibration”,
and the introduction of Annexes E, F and G.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2005-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-02-01
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 61746:2005 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
IEC 60825-1 NOTE Harmonized as EN 60825-1:1994 (not modified).
IEC 60825-2 NOTE Harmonized as EN 60825-2:2004 (not modified).
