23、ylindrical 8 degrees angled-APC composite ferrule using titanium as fibre surrounding material, single mode fibre FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committe

24、es). 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, Technical Reports, Publicly Available

25、 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, governmental and non- governmental organi

26、zations 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 or agreements of IEC on technical ma

27、tters 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 international use and are accepted by IEC Natio

28、nal 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 to promote international uniformity, I

29、EC 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 indicated in the latter. 5) IEC prov

30、ides 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 attach to IEC or its directors, employ

31、ees, 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 fees) and expenses arising out of the

32、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 publication. 9) Attention is drawn to the po

33、ssibility 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 61755-3-8 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passiv

34、e components, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: FDIS Report on voting 86B/2769/FDIS 86B/2802/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above tabl

35、e. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 61755-3-8 IEC:2009 A list of all parts of the IEC 61755 series, published under the general title Fibre optic interconnecting devices and passive components Fibre optic connector optical interfaces, can be foun

36、d on the IEC website. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the time of the next edition. The committee has decided that the contents of this publication will remain unchanged until the maintena

37、nce 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 edition, or amended. 61755-3-8 IEC:2009 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE C

38、OMPONENTS FIBRE OPTIC CONNECTOR OPTICAL INTERFACES Part 3-8: Optical interface, 2,5 mm and 1,25 mm diameter cylindrical 8 degrees angled-APC composite ferrule using titanium as fibre surrounding material, single mode fibre 1 Scope This part of IEC 61755 defines dimensional limits and material proper

39、ties 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 interconnection. The composite ferrule uses different materials in the end face contact zone and in ferrule to sleeve contact zone. The specified materials for

40、 each zone are zirconia (ZrO 2 ) for the ferrule to sleeve contact zone and titanium for the end face contact zone. Ferrules made from the material specified in this standard are suitable for use in categories C, U, E and O as defined in IEC 61753-1. NOTE If mated within the same family (cylindrical

41、 APC ferrule), the ferrules specified in this standard are intended to have the same optical attenuation performance grade for connections with all ferrules described in different parts of IEC 61775-3. 2 Description The performance of a cylindrical ferrule optical interface is determined by the accu

42、racy with which the optical datum targets of two mating ferrules are aligned with each other. There are three conditions affecting the alignment of two optical datum targets, lateral offset, angular offset and longitudinal offset. Parameters influencing the lateral and angular offset of the optical

43、fibre axes include the following: ferrule outside diameter; fibre hole concentricity relative to the ferrule outside diameter; fibre hole angle relative to outside diameter axis; fibre cladding diameter to fibre hole clearance; alignment sleeve inside diameter; fibre core concentricity relative to t

44、he cladding diameter; fibre core orientation relative to keying feature. Parameters influencing the longitudinal offset of the optical fibre axes include the following: end face spherical radius; end face spherical radius apex offset; fibre undercut; axial force on ferrule end face; ferrule and fibr

45、e material physical constants; alignment sleeve frictional force; keying accuracy. 6 61755-3-8 IEC:2009 3 Interface parameters for APC ferrule independent from the ferrule material No sharp edge K D J Ferrule axis Fibre axis IEC 2348/08 Figure 1 Interface dimensions for APC ferrule F IEC 1315/06 Fig
