IEC 62129-3:2019

Calibration of wavelength/optical frequency measurement instruments - Part 3:Optical frequency meters internally referenced to a frequency comb

IEC 62129-3:2019 describes the calibration of optical frequency meters using an optical frequency comb as an internal reference. It is applicable to instruments measuring the optical frequency emitted from sources that are typical for the fibre-optic communications industry. It is assumed that the optical radiation will be coupled to the optical frequency meter by a single-mode optical fibre. This document is part of the IEC 62129 series on the calibration of wavelength/optical frequency measurement instruments. Refer to IEC 62129­1 [3] for the calibration of optical spectrum analyzers, and refer to IEC 62129-2 [4] for calibration of Michelson interferometer single wavelength meters. This first edition cancels and replaces IEC TS 62129-3, published in 2014. This edition includes the following significant technical changes with respect to the previous edition:
a) text has been added to 5.2.3 about calibration at a second optical frequency;
b) Annex D is now normative;
c) Subclause 4.2 has been improved;
d) measurement method of frequency has been moved to Annex B;
e) example of optical frequency comb has been moved to Annex C;
f) frequency-dependence uncertainty has been moved to Annex D.
Keywords: calibration of optical frequency meters

Étalonnage des appareils de mesure de longueur d'onde/appareil de mesure de la fréquence optique - Partie 3 : Fréquencemètres optiques faisant référence en interne à un peigne de fréquence

IEC 62129-3:2019 décrit l'étalonnage des fréquencemètres optiques à l'aide d'un peigne de fréquence optique en référence interne. Elle s'applique aux appareils de mesure de la fréquence optique provenant des sources habituelles dans les secteurs des communications à fibres optiques. Il est pris pour hypothèse que le rayonnement optique est couplé au fréquencemètre optique par une fibre optique unimodale. Le présent document fait partie de la série IEC 62129 relative à l'étalonnage des appareils de mesure de longueur d'onde/appareils de mesure de la fréquence optique. Voir l'IEC 62129­1 [3] pour l'étalonnage des analyseurs de spectre optique, et l'IEC 62129­2 [4] pour l'étalonnage des appareils de mesure de longueur d'onde unique à interféromètre de Michelson. Cette première édition annule et remplace l'IEC TS 62129-3, parue en 2014.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente.
a) un texte a été ajouté en 5.2.3 concernant l'étalonnage à une seconde fréquence optique;
b) l'Annexe D est désormais normative;
c) Le paragraphe 4.2 a été amélioré;
d) la méthode de mesure de la fréquence a été déplacée à l'Annexe B;
e) l'exemple de peigne de fréquence optique a été déplacé à l'Annexe C;
f) l'incertitude de dépendance à la fréquence a été déplacée à l'Annexe D.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
