62077 © IEC:2001– 7 –INTERNATIONAL ELECTROTECHNICAL COMMISSION___________FIBRE OPTIC CIRCULATORS –GENERIC SPECIFICATIONFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)
In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)
Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 62077 has been prepared by subcommittee 86B: Fibre opticinterconnecting devices and passive components, of IEC technical committee 86: Fibre optics.The text of this standard is based on the following documents:FDISReport on voting86B/1443/FDIS86B/1499/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.The QC number that appears on the front cover of this publication is the specification numberin the IEC Quality Assessment System for Electronic Components (IECQ).The committee has decided that the contents of this publication will remain unchangeduntil 2008. At this date, the publication will bereconfirmed;withdrawn;replaced by a revised edition, oramended.SIST EN 62077:2002

62077 © IEC:2001– 19 –2 RequirementsThe requirements for circulators covered by this clause are intended to aid in classifying thisdevice.2.1 ClassificationFibre optic circulators shall be classified as follows:–type;–style;–variant;–environmental category;–assessment level;–normative reference extensions. An example of a typical circulator classification is as follows:Table 1 – Example of a typical connector set classificationType:Style:Variants:Environmental category:Assessment level:Normative referenceextensions: –Three port circulator–Completely circulated type–Operating wavelength: 1,3 µm–Configuration: B–Connector type: FC–Fibre type: IEC type B 1,2–Means of mounting–…………………….–………………………–………………………2.1.1 TypeCirculators are mainly divided into types by their configuration.–Port numbers–Completely circulated type/non-completely circulated type.NOTE
Other kinds of type classification are also available, e.g.:–
according to the operational principles; designs based on magneto-optic Faraday effect, Cotton-Mouton effectand Kerr effect;–
according to the operating wavelength; short wavelength circulators (e.g. 0,63 µm), and long wavelengthcirculators (e.g. 1,30 µm, 1,55 µm), etc.SIST EN 62077:2002
62077 © IEC:2001– 21 –2.1.2 StyleOptical circulators may be classified into styles based upon fibre type(s), connector type(s),cable type(s), housing shape and dimensions, and configuration.The configuration of the circulator ports is classified as follows.Configuration A – Device containing integral fibre optic pigtails without connector:CirculatorPigtailConfiguration B – Device containing integral fibre optic pigtails, with a connector on eachpigtail:CirculatorConnectorConnectorConfiguration C – Device containing connectors as an integral part of the device housing:CirculatorConnectorConfiguration D – Device containing some combination of the interfacing features of thepreceding configurations, for example:CirculatorConnectorPigtail2.1.3 VariantThe circulator variant identifies those common features which encompass structurally similarcomponents (see 3.2). Examples of features which define a variant include, but are not limitedto, the following:–position and orientation of ports on housing;–means of mounting. 2.1.4 Environmental categoryVarious environmental categories are given in the blank detail specifications associated withthis standard; these define the test sequences needed for quality assurance.Detail specification writers may add tests and/or groups of tests to a particular environmentalcategory.SIST EN 62077:2002
62077 © IEC:2001– 23 –However, the detail specification writer shall not remove tests nor alter the sequence of anenvironmental category standard.When a detail specification writer adds tests to a specified category, the environmentalcategory shall be given a plus (+) designation.EXAMPLE:–environmental category ii +–environmental category v +The blank detail specification for environmental category 99 is available for use where thecategory standards are not suitable.2.1.5 Assessment levelAssessment level defines the inspection levels and the acceptable quality level (AQL), ofgroups A and B and the periodicity of inspection of groups C and D. Detail specifications shallspecify one or more assessment levels, each of which shall be designated by a capital letter.The following are preferred levels:• Assessment level A:–group A inspection: inspection level II, AQL = 4 %–group B inspection: inspection level II, AQL = 4 %–group C inspection: 24-month periods–group D inspection: 48-month periods• Assessment level B:–group A Inspection: inspection level II, AQL = 1 %–group B inspection: inspection level II, AQL = 1 %–group C inspection: 18-month periods–group D inspection: 36-month periods• Assessment level C:–group A inspection: inspection level II, AQL = 0,4 %–group B inspection: inspection level II, AQL = 0,4 %–group C inspection: 12-month periods–gr
