31、EMENT PROCEDURES Part 3-7: Examinations and measurements Wavelength dependence of attenuation and return loss of single mode components FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisingall national electrotechnicalcommittees (I

32、EC National Committees). The object of IEC is to promoteinternational 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 St andards, Technical Specifications,TechnicalReports,

33、Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IECPublication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interestedin the subject dealtwith may participate in this preparatory work. International,governmental and non-govern

34、mental organizations liaising with the IEC also participate in thispreparation. IEC collaborates closelywith the International Organization for Standardization (ISO) in accordance with conditions determined byagreement between the two organizations.2) The formal decisions or agreements of IEC on tec

35、hnical matters express, as nearlyas possible, an internationalconsensus ofopinion on the relevant subjects since each technical committee has representation from allinterested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC

36、NationalCommittees in that sense. While all reasonable efforts are made to ensure that the technical content of IECPublications is accurate, IEC cannot be held responsible for the way in which they are used or for anymisinterpretation by any end user.4) In order to promote international uniformity,

37、IEC National Committees undertake to apply IEC Publicationstransparently to the maximum extent possible in their national and regional publications. Any divergencebetween any IEC Publication and the corresponding national or regional publication shall be clearly indicated inthe latter.5) IEC provide

38、s no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformitywith an IEC Publication.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, se

39、rvants or agents including individual experts andmembers of its technical committees and IEC NationalCommittees for any personal injury, property damage orother damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) andexpenses arising out of the publication

40、, use of,or reliance upon, this IEC Publication or any other IECPublications.8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications isindispensable for the correct application of this publication.9) Attention is drawn to the possibility that s

41、ome of the elements of this IEC Publication may be the subject ofpatent rights. IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61300-3-7 hasbeen prepared by subcommittee 86B: Fibre opticinterconnecting devicesand passive components, of IEC

42、technical committee 86: Fibre optics.This second edition cancels and replaces the first edition published in 2000. It constitutes atechnical revision.Changes from the previousedition of this standardare to reflect changesmade to IEC 61300-1and covers unidirectional and bi-directional methods of meas

45、decided that the contents of thispublication will remain unchanged u ntil the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ inthe data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replacedbya revised edition,

47、eturn loss of single mode components 1 Scope This part of IEC 61300-3 describes the various methods available to measure the wavelengthdependence of attenuation A ( ) and returnloss RL( ), ofsingle-mode passive opticalcomponents (POC) used in fibre-optic (FO) telecommu nications. Itisnot, however, a

48、pplicable to dense wavelength division multiplexing (DWDM) devices.Measurement methodsofwavelength dependence of attenuation of DWDM devices are described in IEC 61300-3-29. DefinitionofWDM device types is given in IEC 62074-1.Three measurement cases are herein considered: Measurement of A ( ) only;

49、 Measurement of RL( ) only; Measurement of A ( ) and RL( ) at the same time. These measurements may be performed in one direction (unidirectional) or bi-directionally.2 Normative referencesThe following referenced documents are indispensable for the application of this document.For dated references, only the edition cited applies.
