24、T AND MEASUREMENT PROCEDURES Part 3-45: Examinations and measurements Attenuation of random mated multi-fibre connectors FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National C
25、ommittees). 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 Av
26、ailable Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental
27、 organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on techn
28、ical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IE
29、C National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, 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 unifor
30、mity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) I
31、EC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure
32、 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 personal injury, property damage or other damage of any
33、 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 references cited in this publication. Use of the refer
34、enced 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 identifying any or all such patent rights. Intern
35、ational Standard IEC 61300-3-45 Ed.1.0 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: FDIS Report on voting 86B/3177/FDIS 86B/3215/RVD Full
36、information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. 4 61300-3-45 IEC:2011 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The list of all parts of IEC 61300 series, published under the gen
37、eral title, Fibre optic interconnecting and passive components Basic test and measurement procedures, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.ie
38、c.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61300-3-45 IEC:2011 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-45: Examinatio
39、ns and measurements Attenuation of random mated multi-fibre connectors 1 Scope The purpose of this part of IEC 61300 is to describe the procedure required to measure the statistical distribution and mean attenuation for random mated optical connectors with physical contact (PC) and angled physical c
40、ontact (APC) polished 1-row multi-fibre rectangular ferrules as defined in the IEC 61754 series. This measurement method is applicable to cable assemblies. 2 Normative references The following referenced documents are indispensable for the application of this document.

Both provide an estimate of the expected average per
44、formance that a group of cable assemblies (including an adaptor, if applicable) selected from a batch will exhibit when used in an optical system. The cable assemblies, and any adaptors, must be chosen at random to ensure that the measurements provide a statistically unbiased estimate. Method 1 desc
45、ribes the procedure using a sample of cable assemblies and adaptors specified in Table 1. In this case the plugs (with pins) are used as “reference” plugs and the plugs (without pins) are tested against them sequentially. The results, based on the number of measurements specified in Table 1, are rec
46、orded in the test matrix shown in Figures 3 to 5. Method 1 is intended to be part of a design approval exercise that may involve one or more suppliers. Once approval is achieved, Method 2 would be relied on to maintain process control. However, in the event of a dispute, Method 1 shall act as the re
47、ference measurement method. 6 61300-3-45 IEC:2011 Method 2 describes a procedure for the measurement of a sample of cable assemblies specified in Table 2. Three cable assemblies are selected from the sample as “reference” cable assemblies and pins are fitted. The other test cable assemblies (without
48、 pins) are tested against each of the three “reference cable assemblies” sequentially. This produces the number of measurements specified in Table 2 and the results are recorded in the test matrix shown in Figures 10 to 12. It is recognised that the number of measurements required by Method 1 may be
49、 excessive for day-to-day routine checking of either in-house or supplier produced products. In this case, as indicated above, Method 2 may be an alternative option. NOTE In this measurement method, the terms “reference” plug or “reference” cord are used to define those components chosen at random from a batch, against which a number of comparat
