24、on FOREWORD 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
25、the 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 entruste
26、d to 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 Internati
27、onal 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
28、 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 National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
29、 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 uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in thei
30、r 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) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declare
31、d to be in conformity with 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 C
32、ommittees 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 publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is draw
33、n 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 possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not
34、be held responsible for identifying any or all such patent rights. International Standard IEC 60794-3-30 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical committee 86: Fibre optics. This standard is to be used in conjunction with IEC 60794-1-1 and IEC 60794-1-2, and IEC 607
35、94-3. This second edition cancels and replaces the first edition published in 2002. This edition constitutes a technical revision. The main changes with respect to the previous edition are listed below: the title of the specification has been updated to include coastal applications; fibres specifica
36、tion have been enlarged to include fibre Type B5; an annex has been added for additional requirements according to the MICE table. 4 60794-3-30 IEC:2008 This bilingual version, published in 2008-07, corresponds to the English version. The text of this standard is based on the following documents: FD
37、IS Report on voting 86A/1203/FDIS 86A/1222/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. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO
38、/IEC Directives, Part 2. A list of all parts of IEC 60794 series, under 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
39、 “http:/webstore.iec.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. 60794-3-30 IEC:2008 5 OPTICAL FIBRE CABLES Part 3-30: Outdoor cables Family specification for optical telecommunication c
40、ables for lakes, river crossings and coastal application 1 Scope This family specification covers optical telecommunication cables to be used as underwater cables for lakes, river crossings and coastal applications. Requirements of the sectional specification IEC 60794-3 for duct, buried, aerial and
41、 lake, river crossings and coastal applications cables are applicable to cables covered by this standard. This standard does not cover methods of cable repair nor repair capability, nor does it cover cables for use with lake, river crossings and coastal applications line amplifiers. Clause 4 of this
42、 standard describes a blank detail specification for optical telecommunication cables to be used for lakes, river crossings and coastal applications. It incorporates some minimum requirements. Annex A describes a blank detail specification which may be used to prepare detail specifications. Annex B
43、describes the cable construction. Annex C describes a blank detail specification for ISO/IEC 24702 applications (MICE). The parameters specified in this standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of suitable standards.
44、 Acceptance criteria are interpreted with respect to this consideration (see IEC 60794-3, Clause 9). The number of fibres tested should be representative of the cable design and should be agreed between the customer and the supplier. 2 Normative references The following referenced documents are indi
45、spensable for the application 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. They complete the normative references already listed in the generic specification (IEC 6079
46、4-1-1, Clause 2 and IEC 60794-1-2, Clause 2) and in the sectional specification (IEC 60794-3, Clause 2).
