22、Part 3-6: Optical interface 2,5 mm and 1,25 mm diameter cylindrical 8 degrees angled-PC composite ferrule using Cu-Ni-alloy as fibre surrounding material, single mode fibre FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all

23、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 other activities, IEC publishes International Standards, Tech

24、nical 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 subject dealt with may participate in this preparatory wor

25、k. 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 determined by agreement between the two organizations. 2)

26、 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 Committees. 3) IEC Publications have the form of recommend

27、ations 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 which they are used or for any misinterpretation by any en

28、d 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 Publication and the corresponding national or regional publica

29、tion 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 not responsible for any services carried out by independe

30、nt 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 technical committees and IEC National Committees for any pers

31、onal 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 ref

32、erences 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 fo

33、r identifying any or all such patent rights. This consolidated version of IEC 61755-3-6 consists of the first edition (2006) documents 86B/2260/CDV and 86B/2365/RVC and its amendment 1 (2012) documents 86B/3335/FDIS and 86B/3389/RVD. It bears the edition number 1.1. The technical content is therefor

34、e identical to the base edition and its amendment and has been prepared for user convenience. A vertical line in the margin shows where the base publication has been modified by amendment 1. Additions and deletions are displayed in red, with deletions being struck through. 4 61755-3-6 IEC:2006+A1:20

35、12 International Standard IEC 61755-3-6 has been prepared by sub-committee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC

36、 61755 series, published under the general title Fibre optic connector optical interface, can be found on the IEC website. The committee has decided that the contents of the base publication and its amendments will remain unchanged until the stability date indicated on the IEC web site under “http:/

37、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. IMPORTANT The “colour inside” logo on the cover page of this publication indicates that it contains colours which are considered

38、to be useful for the correct understanding of its contents. Users should therefore print this publication using a colour printer. 61755-3-6 IEC:2006+A1:2012 5 FIBRE OPTIC CONNECTOR OPTICAL INTERFACES Part 3-6: Optical interface 2,5 mm and 1,25 mm diameter cylindrical 8 degrees angled-PC composite fe

39、rrule using Cu-Ni-alloy as fibre surrounding material, single mode fibre 1 Scope This part of IEC 61755 defines dimensional limits and material properties of a 2,5 mm and a 1,25 mm diameter cylindrical composite ferrule optical interface to meet specific requirements for APC fibre-to-fibre interconn

40、ection. The composite ferrule uses different materials in the end face contact zone and in the ferrule to sleeve contact zone. The specified materials for each zone are Zirconia (ZrO2) for the ferrule to sleeve contact zone and Cu-Ni-alloy for the end face contact zone. Ferrules made from the materi

41、al specified in this document are suitable for use in categories C, U and O as defined in IEC 61753-1. NOTE If mated within the same family (cylindrical APC ferrule), the ferrules specified in this document are intended to have the same optical attenuation performance grade for connections with all

42、ferrules described in IEC 61755-3 documents. 2 Description The performance of a cylindrical ferrule optical interface is determined by the accuracy with which the optical datum targets of two mating ferrules are aligned with each other. There are three conditions affecting the alignment of two optic

43、al datum targets, lateral offset, angular offset and longitudinal offset. Parameters influencing the lateral and angular offset of the optical fibre axes include ferrule outside diameter; fibre hole concentricity relative to the ferrule outside diameter; fibre hole angle relative to outside diameter

44、 axis; fibre cladding diameter to fibre hole clearance; alignment sleeve inside diameter; fibre core concentricity relative to the cladding diameter; fibre core orientation relative to keying feature. Parameters influencing the longitudinal offset of the optical fibre axes include the following: end

45、 face spherical radius; end face spherical radius apex offset; fibre undercut; axial force on ferrule end face; ferrule and fibre material physical constants; alignment sleeve frictional force; keying accuracy. 6 61755-3-6 IEC:2006+A1:2012 3 Interface parameters The optical interface dimensions are
