28、 category C single-mode intraconnection fibres 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
29、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 Available Specifications (PAS) and Guides (hereafter referred to as “IEC Pub
30、lication(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 organizations liaising with the IEC also participate in this preparation.
31、 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 technical matters express, as nearly as possible, an international consensus of
32、 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 National Committees in that sense. While all reasonable efforts are made
33、 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 uniformity, IEC National Committees undertake to apply IEC Publications transpar
34、ently 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) IEC provides no marking procedure to indicate its approval and cannot be re
35、ndered 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 attach to IEC or its directors, employees, servants or agents including individual experts and members of
36、 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 publication, use of, or reliance upon, this IEC Publication or any
37、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 possibility that some of the elements of this IEC Publication may be
38、the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60793-2-60 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical committee 86: Fibre optics. This bilingual version (2012-09) corresponds to
39、the monolingual English version, published in 2008-02.The text of this standard is based on the following documents: CDV Report on voting 86A/1160A/CDV 86A/1201/RVC 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
40、 French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 60793-2-60 IEC:2008 5 A list of all parts of the IEC 60793 series can be found, under the general title Optical Fibres, on the IEC website. The committee has
41、 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 publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edit
42、ion; or amended. 6 60793-2-60 IEC:2008 OPTICAL FIBRES Part 2-60: Product specifications Sectional specification for category C single-mode intraconnection fibres 1 Scope This part of IEC 60793 is applicable to optical fibre types C1, C2, C3, C4, as described in Table 1. These fibres are used for the
43、 intraconnections within or between components or photonic systems or subsystems. While the fibres are sold in lengths on the scale of kilometres, they are normally cut into short lengths for use in these intraconnections. While the fibres could be overcoated or buffered for the purpose of making pr
44、otected pigtails, they may be used without overcoating. They may, however, be colour-coded. The general requirements defined in IEC 60793-2 apply to these fibres. Specific requirements that are common to these fibres are found in the body of this text. Particular requirements for individual fibre ty
45、pes or applications are defined in Annexes A, B, C and D, which refer to normative family specifications. These family specifications are distinguished based on optimum transmission wavelengths and nominal Mode Field Diameter (MFD), which affects splice loss. For each family specification, there are
46、 two sub-categories that are distinguished on the basis of the cladding diameter and other related attributes. The conventional nominal cladding diameter of 125 m is augmented with the reduced cladding type product with a nominal diameter of 80 m. These are distinguished with the suffixes: “_125” or
47、 “_80”. For example C1 fibre can be selected as either C1_125 or C1_80. The transmission characteristics of the two cladding diameter choices should be the same. For each family specification except C1, there are two sub-categories that are distinguished on the basis of transmission characteristics
48、that relate to MFD. To denote these sub- categories, a “_a“ or “_b“ suffix is added, for lower or higher MFD. In general, the fibres can be optimised for either splice loss or macro-bend loss using MFD as a main variable. A C2 fibre with 80 m cladding diameter and lower MFD is designated as C2_80_a.
49、 Fibres for the C1_125 family specification can be selected fom category B1.1 or B1.3 single- mode fibres and are suitable for use with any category B single-mode fibre at wavelengths from 1 280 nm to 1 625 nm. Fibres for the C2 and C3 family specifications are optimized at nominal wavelengths of 1 310 nm and 1 550 nm respectively for connection to any category B single-mo
