12、orldwide 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 electronic fields. To this end and in addition to othe
13、r 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; any IEC National Committee interested in the s
14、ubject 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 Standardization (ISO) in accordance with conditions
15、 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 representation from all interested IEC National
16、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, IEC cannot be held responsible for the way in
17、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 publications. Any divergence between any IEC Publ
18、ication 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 services and, in some areas, access to IEC marks of conformity. IEC is
19、 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, servants or agents including individual experts and members of its tec
20、hnical 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 other IE
21、C 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 the subj
22、ect of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when th
23、e required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technic
24、al specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC TS 62965, which is a Technical Specification, has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IE
25、C technical committee 86: Fibre optics. PD IEC/TS 62965:2016 4 IEC TS 62965:2016 IEC 2016 The text of this Technical Specification is based on the following documents: Enquiry draft Report on voting 86B/3971/DTS 86B/3986/RVC Full information on the voting for the approval of this technical specifica
26、tion can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under
27、“http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended.

28、EVICES AND PASSIVE COMPONENTS Ferrule assembly and fusion splicer interface dimensions for a fusion splice on connector 1 Scope IEC TS 62965, which is a Technical Specification, specifies a minimum set of dimensional requirements for fusion splice on connectors (FSOCs) ferrule assemblies and the int
29、erface dimensions of splicing tools to ensure that a compliant ferrule assembly is compatible with a compliant fusion splicer. This fusion splicer interface also provides an example of the dimensional requirements for a universal holder, into which an FSOC can be mounted. This fusion splicer interfa
30、ce applies to FSOCs with a cylindrical ferrule of 2,5 mm diameter or 1,25 mm diameter. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited ap
31、plies. For undated references, the latest edition of the referenced document (including any amendments) applies. There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminologic
32、al databases for use in standardization at the following addresses: IEC Electropedia: available at http:/www.electropedia.org/ ISO Online browsing platform: available at http:/www.iso.org/obp 3.1 ferrule assembly component of an FSOC, which consists of a factory polished cylindrical ferrule, a flang

34、 is fixed to the ferrule and factory polished with the endface of the ferrule, and the another end extends out of the flange and has a cleaved endface PD IEC/TS 62965:2016 6 IEC TS 62965:2016 IEC 2016 4 Description This fusion splicer interface defines the minimum dimensional limits and relative loc
35、ations of an FSOC ferrule assembly within a fusion splicer to ensure that the fusion splicer is able to complete the splicing process. This document also provides information on an example universal holder to accommodate the FSOC ferrule assembly. Other FSOC components such as connector housings, du
36、st caps or reinforcing sleeve do not affect the compatibility, so their dimensions are not addressed in this fusion splicer interface. It should be noted that this fusion splicer interface ensures only the compatibility between the FSOC ferrule assembly and fusion splicing tools, and does not ensure
37、 the compatibility of FSOC components of different models. 5 Interfaces 5.1 General This document defines a minimum set of dimensional requirements for the ferrule assembly and the fusion splicer. The dimensions of the ferrule assembly are given in Figure 1 and Table 1 (for the 2,5 mm diameter type)
38、 and Table 2 (for the 1,25 mm diameter type). The interface of the fusion splicer is given in Figure 2 and Table 3. 5.2 Dimensions of the ferrule assembly Figure 1 Ferrule assembly dimensions Table 1 Dimensions for a 2,5 mm diameter cylindrical ferrule assembly Dimensions in millimetres Reference Di

44、ce Typically, each FSOC model has its original holder interface, i.e. a combination of a dedicated ferrule assembly holder design and one of its applicable fusion splicer models, so that the installation is optimised. This annex is provided as a guideline for users who plan to design/use a universal
45、 holder for various FSOC ferrule assemblies. It should be noted that the use of a universal holder may adversely affect the installation of the FSOC ferrule assembly in comparison to using the original purpose-designed ferrule holder, but not the performance of the assembled FSOC. In conjunction wit
46、h Figure A.1, examples of two universal holder interfaces are given in Table A.1 (for a 2,5 mm diameter ferrule type) and in Table A.2 (for a 1,25 mm ferrule type). These two examples are provided as sets of dimensional limits for a combination of the 2,5 mm or 1,25 mm ferrule assembly holders and t
47、he fusion splicer. Universal holders complying with these interfaces can accommodate any of the ferrule assemblies with their corresponding ferrule diameters as specified in this document. In Figure A.1, dimension B hvaries during the fusion splicing process as the holder stage of the fusion splicer
48、 moves. In this fusion splicer interface, the B hbasic dimension is defined as the distance at the time of fusion splicing. Any value greater than B hbasic is allowed for B hbefore the holder stage moves, as long as B hcan become equal to B hbasic at some point within the range of the holder stage m
49、ovement. The minimum limits for C hand E hhave some margin against corresponding maximum limits for the ferrule assembly, C fand E f , respectively, shown in Figure 1. These margins allow positional adjustment of the ferrule assembly in its holder to achieve fibre end placement between the electrodes and the fibre alignment block prior to fusion splicing. This fusion splicer inter face does not define the means to fix the ferrule assembly holder
