Calibration of wavelength/optical frequency measurement instruments - Part 2: Michelson interferometer single wavelength meters
IEC 62129-2:2011 is applicable to instruments measuring the vacuum wavelength or optical frequency emitted from sources that are typical for the fibre-optic communications industry. These sources include Distributed Feedback (DFB) laser diodes, External Cavity lasers and single longitudinal mode fibre-type sources. This standard is part of the IEC 62129 series on the calibration of wavelength/optical frequency measurement instruments. Refer to IEC 62129 for the calibration of optical spectrum analyzers.

La CEI 62129-2:2011 est applicable aux instruments mesurant la longueur d'onde ou la fréquence optique dans le vide émise par des sources types de l'industrie des communications par fibres optiques. Ces sources comportent des diodes laser DFB (à rétroaction répartie, Distributed Feedback), des lasers à cavité externe et des sources du type à fibres unimodales longitudinales. La présente norme fait partie de la série CEI 62129 relative à l'étalonnage des appareils de mesure de longueur d'onde/appareils de mesure de fréquence optique. Se référer à la CEI 62129 pour l'étalonnage des analyseurs de spectre optique.
Kalibriranje valovno-dolžinskih/optično-frekvenčnih merilnih instrumentov - 2. del: Merilniki ene valovne dolžine z Michelsonovim interferometrom (IEC 62129-2:2011)
Ta del IEC 62129 velja za instrumente, ki merijo vakuumsko valovno dolžino ali optično frekvenco, ki jo oddajajo viri, značilni za industrijo komunikacije z optičnimi vlakni. Ti viri vključujejo laserske diode s porazdeljenim povratnim sklopom (DFB), laserje z zunanjo votlino in vire z enorodnim vzdolžnim vlaknom. Domneva se, da se optično sevanje sklopi z merilnikom valovnih dolžin z enorodnim optičnim vlaknom. Standard opisuje kalibracijo merilnikov valovnih dolžin, ki se izvaja v kalibracijskih laboratorijih ali pri proizvajalcih merilnikov valovnih dolžin. Ta standard je del serije IEC 62129 o kalibraciji valovno-dolžinskih/optično-frekvenčnih merilnih instrumentov. Za kalibracijo analizatorjev optičnega spektra glej IEC 62129.

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 a
