25、rnational 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 elec
26、tronic 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 committe
27、es; 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 S
28、tandardization (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 as possible, an international consensus of opinion on the relevant subjects since each technical committee ha
29、s representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accura
30、te, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional
31、 publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity w
32、ith 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, servants or agents including individual experts and members of its technical committees and IEC National Committees for any perso
33、nal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative refe
34、rences cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for
35、 identifying any or all such patent rights. International Standard IEC 61300-3-2 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This third edition cancels and replaces the second edition published in 199
36、9. It constitutes a technical revision. The main changes with respect to the previous edition are listed below: This edition includes both the all-states method of the previous edition as well as the Mueller matrix method from IEC 61300-3-12. 4 61300-3-2 IEC:2009 This bilingual version (2013-07) cor
37、responds to the monolingual English version, published in 2009-01. The text of this standard is based on the following documents: FDIS Report on voting 86B/2783/FDIS 86B/2811/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the ab
38、ove table. The French version of this standard has not been voted upon. A list of all parts of IEC 61300 series, published under the general title Fibre optic interconnecting devices and passive components Basic test and measurement procedures, can be found on the IEC website. This publication has b
39、een drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this
40、date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should the

42、00 specifies measurement methods to determine the dependence of loss in a single-mode fibre optic device to changes in polarization. This procedure focuses on measurements with a fixed wavelength source; therefore, this procedure is applicable to devices whose properties at a single wavelength can r
43、epresent those over the broader wavelength band. Typical examples of such devices are single-mode interconnecting devices and passive components, including connectors, splices, branching devices, attenuators, isolators, and switches. The maximum observed variation in transmission loss is referred to
44、 as polarization-dependent-loss (PDL). This standard applies to broadband devices and not to narrow-band devices like filters and multiplexers. The reader is referred to IEC 61300-3-29 for such measurements. 2 Normative references The following referenced documents are indispensable for the applicat
45、ion of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

46、3-29: Examinations and measurements Measurement techniques for characterising the amplitude of the spectral transfer function of DWDM components 3 Measurement methods Two methods for measuring polarization-dependent-loss are described. The all states method determines the maximum variation in transm
47、ission loss by stimulating with a representative set of all possible polarization states including linear, circular, and elliptical. The Mueller matrix method determines the sensitivity using a set of fixed states and applying the Mueller matrix mathematical analysis. This procedure originally consi
48、sted of only one method, but has been updated to incorporate the technique previously described by IEC 61300-3-12 1 . That standard will be discontinued. 3.1 All states method In this method, the PDL is determined by rotating the source polarization over a representative set of all possible polariza
