23、OREWORD 1) The International 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
24、electrical and electronic 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
25、 technical committees; 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
26、Organization for Standardization (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 tech
27、nical 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 National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publ
28、ications 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 uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their nat
29、ional and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment se
30、rvices 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 that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, se
31、rvants 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 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publica
32、tion, 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 referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibili
33、ty 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. International Standard IEC 60793-2 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical committee 86: Fibre
34、 optics. This eighth edition cancels and replaces the seventh edition published in 2011. This edition constitutes a technical revision which was necessary due to the addition of new fibre models to the A1 category in IEC 60793-2-10. This edition includes the following significant technical changes w
35、ith respect to the previous edition: a) addition of two new sub-categories A3f and A3g indicated “under consideration” as they have not yet been fully standardized at the moment of finalizing this document; b) modification of the Numerical aperture heading in Table 3 in line with recent modification
36、s in all A1, A2, A3 and A4 multimode product specifications (NAffonly). This standard is to be read in conjunction with the IEC 60793-1 series. BS EN 60793-2:2016 4 IEC 60793-2:2015 IEC 2015 The text of this standard is based on the following documents: CDV Report on voting 86A/1645/CDV 86A/1663/RVC
37、 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 all parts in the IEC 60793 series, published under the general title Opt
38、ical fibres, 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 website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will
39、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 therefore print this document
40、using a colour printer. BS EN 60793-2:2016IEC 60793-2:2015 IEC 2015 5 OPTICAL FIBRES Part 2: Product specifications General 1 Scope This part of IEC 60793 contains the general specifications for both multimode and single-mode optical fibres. Sectional specifications for each of the four categories m
41、ultimode fibres: A1, A2, A3, and A4 (part of the multimode fibre class A) contain requirements specific to each category. Sectional specifications for each of the two single-mode fibre classes, B and C, contain requirements common to each class. Each sectional specification includes family specifica
42、tions (in normative annexes) that contain requirements for the applicable category or sub-categories. These sub-categories are distinguished on the basis of different fibre types or applications. The requirements of this standard apply to all classes. Each sectional specification contains the requir
43、ements that are common to all the family specifications that are within it. These common requirements are copied to the family specification for ease of reference. Tests or measurement methods are defined for each specified attribute. Where possible, these definitions are by reference to an IEC stan
44、dard otherwise the test or measurement method is outlined in the relevant sectional specification. Table 1 defines the sectional specifications. The relevant family specifications are defined within the sectional specifications as normative annexes (see Tables 2 to 5). Annexes A and B summarize the
45、existing fibre specifications.
