23、tional 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 electro
24、nic 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 committees;
25、 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 Stan
26、dardization (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 has r
27、epresentation 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 accurate,
28、 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 pu
29、blications. 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 with
30、 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 personal
31、 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 referen
32、ces 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 id
33、entifying any or all such patent rights. International Standard IEC 60794-2-42 has been prepared by sub-committee 86A: Fibres and cables, of IEC technical committee 86: Fibre optics. This standard is to be used in conjunction with IEC 60794-1-1, IEC 60794-1-2 and IEC 60794-2. This bilingual version
34、(2012-01) corresponds to the monolingual English version, published in 2008-04. The text of this standard is based on the following documents: CDV Report on voting 86A/1126/CDV 86A/1155/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicate
35、d in the above table. 4 60794-2-42 IEC:2008 The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A blank detail specification is provided in Annex B. A list of all parts of the IEC 60794 series, published un
36、der the general title Optical fibre cables, can be found on the IEC website. 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 publica
37、tion. At this 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. U
38、sers should therefore print this document using a colour printer. 60794-2-42 IEC:2008 5 OPTICAL FIBRE CABLES Part 2-42: Indoor optical fibre cables Product specification for simplex and duplex cables with A4 fibres 1 Scope This part of IEC 60794 covers simplex and duplex optical fibre cables contain

The cable shall be designed a
48、nd manufactured for an expected operating lifetime of at least 15 years. In this context, the attenuation of the installed cable at the operational wavelength(s) shall not exceed values agreed between customer and supplier. The materials in the cable shall not present a health hazard within its inte
49、nded use. There shall be no fibre splice in a delivery length unless otherwise agreed by customer and supplier. It shall be possible to identify each individual fibre throughout the length of the cable. 3.2 Optical fibres Multimode category A4a through A4g optical fibres shall be used that meet the requirements of IEC 60793-2-40. 3.3 Buffer The
