Fibre optic interconnecting devices and passive components - Fibre optic circulators - Generic specification

IEC 62077:2015(E) applies to circulators used in the field of fibre optics bearing all of the following features: - they are non-reciprocal optical devices, in which each port is either an optical fibre or fibre optic connector; - they are passive devices in accordance with the categorization and definition provided in IEC TS 62538; - they have three or more ports for directionally transmitting optical power. An example of optical circulator technology is described in Annex A. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: harmonization of some terms and definitions with other generic specifications, deletion of assessment level. Keywords: optical circulator

IEC 62077:2015 s’applique aux circulateurs utilisés dans le domaine de la fibronique, présentant toutes les caractéristiques suivantes: · ce sont des dispositifs optiques non réciproques, dont chaque port est soit une fibre optique, soit un connecteur fibronique; · ce sont des dispositifs passifs, conformément à la classification et à la définition données dans l'IEC TS 62538; · ils disposent d'au moins trois ports pour la transmission de la puissance optique de façon directionnelle. Un exemple de technologie pour les circulateurs optiques est décrit en Annexe A. Cette troisième édition annule et remplace la deuxième édition parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: harmonisation de certains termes et définitions avec d'autres spécifications génériques, suppression du niveau d'assurance de la qualité. Mots clés: circulateurs optiques

Optični spojni elementi in pasivne komponente - Optični cirkulatorji - Rodovna specifikacija (IEC 62077:2015)

Ta mednarodni standard se uporablja za cirkulatorje, ki so v uporabi za optična vlakna in imajo naslednje lastnosti:
– so nerecipročne optične naprave, v katerih so vsaka vrata optično vlakno ali optični konektor;
– so pasivne naprave v skladu z razvrstitvijo in definicijo iz standarda IEC TS 62538;
– imajo tri ali več vrat za usmerjen prenos optične moči.
V dodatku A je opisan primer tehnologije optičnega cirkulatorja.

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
