15、SION _ OPTICAL FIBRE CABLES Part 3-10: Outdoor cables Family specification for duct, directly buried and lashed aerial optical telecommunication cables FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechn
16、ical committees (IEC National Committees). 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,
17、 Technical Reports, Publicly Available 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, gov
18、ernmental and non-governmental 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
19、 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 representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for internatio
20、nal 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, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order t
21、o promote international uniformity, 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
22、 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 an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall a
23、ttach 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 nature whatsoever, whether direct or indirect, or for costs (including legal f
24、ees) 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 referenced publications is indispensable for the correct application of this publica
25、tion. 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. International Standard IEC 60794-3-10 has been prepared by subcommittee 86A: Fibres a
26、nd cables, of IEC technical committee 86: Fibre optics. This second edition cancels and replaces the first edition published in 2002. It constitutes a technical revision. The main changes are listed below: the title of the specification has been updated to include lashed applications; the fibres spe
27、cification clause (Clause 4) has been enlarged to include fibre Types B5 and B6.a; an annex has been added for additional requirements according to the MICE table.

28、-10 IEC:2009(E) The text of this standard is based on the following documents: FDIS Report on voting 86A/1245/FDIS 86A/1252/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 acc
29、ordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 60794 series, published 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 indic
30、ated on the IEC web site under “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. A bilingual version of this publication may be issued at a later date. SANS 60794-3-10:2009

32、 60794 which is a family specification covers optical telecommunication cables to be used in ducts or direct buried applications. The cable may also be used for lashed aerial applications. Requirements of the sectional specification IEC 60794-3 for duct, buried and aerial cables are applicable to ca
33、bles covered by this standard. Clause A.2 contains requirements that supersede the normal requirements in case the cables are intended to be used in installation governed by the MICE table of ISO/IEC 24702. Annex B gives information on the lashed aerial application. The parameters specified in this
34、standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of suitable standards. Acceptance criteria shall be interpreted with respect to this consideration (see IEC 60794-3 Clause 8). The number of fibres tested shall be representat
35、ive of the cable design and shall be agreed between the customer and the supplier. 2 Normative references The following referenced documents are indispensable for the application of this document.
