14、ERNATIONAL ELECTROTECHNICAL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS CONNECTOR OPTICAL INTERFACES Part 3-10: Connector parameters of non-dispersion shifted single mode physically contacting fibres Non-angled, ferrule-less, bore alignment connectors FOREWORD 1) The Inte
15、rnational 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 all questions concerning standardization in the electrical and elec
16、tronic 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 Publication(s)”). Their preparation is entrusted to technical committe
17、es; 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. IEC collaborates closely with the International Organization for S
18、tandardization (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 opinion on the relevant subjects since each technical committee ha
19、s 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 to ensure that the technical content of IEC Publications is accura
20、te, 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 transparently to the maximum extent possible in their national and regional
21、 publications. Any divergence between any IEC Publication 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 som
22、e areas, access to IEC marks of conformity. IEC is 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 i
23、ncluding 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 publication, use of, or r
24、eliance 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 possibility that some of th
25、e 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 61755-3-10 has been prepared by sub-committee 86B: Fibre optic interconnecting devices and passive components, of IEC te
26、chnical committee 86: Fibre optics. The text of this standard is based on the following documents: CDV Report on voting 86B/3990A/CDV 86B/4032/RVC Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This do
27、cument has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 IEC 61755-3-10:2016 IEC 2016 A list of all parts in the IEC 61755 series, published under the general title Fibre optic interconnecting devices and passive components Connector optical interfaces, can be found on the IEC we

The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised
29、 edition, or amended. A bilingual version of this publication may be issued at a later date.

30、ing fibres Non-angled, ferrule-less, bore alignment connectors 1 Scope This part of IEC 61755 defines certain dimensional limits of a 125 m diameter single mode silica fibre optical interface and an alignment bore to meet specific requirements for non- angled fibre-to-fibre interconnection as define
31、d in IEC 61755-2-1. The silica fibre materials specified in this document are suitable for use in categories C, U, E and O as defined in IEC 61753-1. 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
32、 this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

35、g fibres 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 fibre axes of this interface include the following: fibr
36、e cladding diameter; alignment bore diameter; 6 IEC 61755-3-10:2016 IEC 2016 length of the bore; fibre core location relative to the fibre cladding diameter centerline. Parameters influencing the optical fibre end face deformation requirements to maintain the physical contact of two mated connectors
37、 to which this interface applies: end face spherical radius; end face angle; fibre tip diameter; axial force on fibre end face; fibre material physical constants. 5 Interface parameters The end face dimensions of prepared fibres are shown in Figure 1. Alignment bore dimensions are shown in Figure 2.
