Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-7: Examinations and measurements - Wavelength dependence of attenuation and return loss of single mode components

This part of IEC 61300-3 describes methods available to measure the wavelength dependence of attenuation and return loss of two port, single mode passive optical components. It is not, however, applicable to dense wavelength division multiplexing (DWDM) devices. Measurement methods of wavelength dependence of attenuation of DWDM devices are described in IEC 61300-3-29. There are two measurement cases described in this standard: a) Measurement of attenuation only; b) Measurement of attenuation and return loss at the same time.

IEC 61300-3-7:2021 décrit les méthodes disponibles de mesure de l’affaiblissement et de l’affaiblissement de réflexion des composants optiques passifs unimodaux à deux ports en fonction de la longueur d'onde. Elle n’est toutefois pas applicable aux dispositifs de multiplexage par répartition en longueurs d'onde à forte densité (DWDM_dense wavelength division multiplexing). Les méthodes de mesure de l’affaiblissement des dispositifs DWDM en fonction de la longueur d'onde sont décrites dans l’IEC 61300-3-29. Le présent document décrit deux cas de mesure: a) mesurage de l’affaiblissement uniquement; b) mesurage simultané de l’affaiblissement et de l’affaiblissement de réflexion. Cette troisième édition annule et remplace la deuxième édition parue en 2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) réduction du nombre de méthodes alternatives proposées afin de les rendre conformes à la pratique industrielle; b) nouvel énoncé des équations relatives à la perte d’insertion et à l’affaiblissement de réflexion utilisant des formes logarithmiques plus courantes dans le secteur de l’industrie; c) recommandations supplémentaires concernant la création de terminaisons de fibres; d) analyse complémentaire de la caractérisation des sources optiques utilisées dans la présente norme; d) simplification des essais bidirectionnels; e) suppression de procédures de mesure distinctes par affaiblissement de réflexion uniquement.
