26、 COMMISSION _ OPTICAL FIBRES Part 2-30: Product specifications Sectional specification for category A3 multimode fibres FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Co
27、mmittees). 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 Ava
28、ilable 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
29、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 techni
30、cal 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 IEC
31、 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 uniform
32、ity, 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) IE
33、C 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
34、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
35、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 refere
36、nced 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. Interna
37、tional Standard IEC 60793-2-30 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical committee 86: Fibre optics. This fourth edition cancels and replaces the third edition published in 2012 and constitutes a technical revision. This edition includes the following significant tec
38、hnical changes with respect to the previous edition: specified test specimen length and measurement details for core diameter and NA ffmeasurements have been added. two new sub-categories have been added NA this replaced by NA ffIEC 60793-2-30:2015 IEC 2015 5 The text of this standard is based on th
39、e following documents: FDIS Report on voting 86A/1661/FDIS 86A/1662/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of a
40、ll parts of the IEC 60793 series can be found, under the general title Optical fibres, 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.iec.ch“ in the data related to
41、 the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains
42、 colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 IEC 60793-2-30:2015 IEC 2015 OPTICAL FIBRES Part 2-30: Product specifications Sectional specification for category A3 multimode fibres 1 Scop
43、e This part of IEC 60793-2 is applicable to sub-categories A3a, A3b, A3c, A3d, A3e, A3f and A3g. These fibres are used or can be incorporated in different information transmission equipment, other applications employing similar light transmitting techniques as well as fibre optic cables. Three types
44、 of requirements apply to these fibres: general requirements, as defined in IEC 60793-2; specific requirements common to the category A3 multimode fibres covered in this standard and which are given in Clause 3; particular requirements applicable to the individual sub-categories or specific applicat
45、ions (e.g. automotive or industrial applications), which are defined in the normative sub- category annexes. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edit
46、ion cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
