The object of IEC is to promote 34 international co-operation on all questions concerning standardization in the electrical and electronic fields. To 35 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, 36 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC 37 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested 38 in the subject dealt with may participate in this preparatory work. International, governmental and non-39 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely 40 with the International Organization for Standardization (ISO) in accordance with conditions determined by 41 agreement between the two organizations. 42 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international 43 consensus of opinion on the relevant subjects since each technical committee has representation from all 44 interested IEC National Committees. 45 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National 46 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC 47 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any 48 misinterpretation by any end user. 49 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications 50 transparently to the maximum extent possible in their national and regional publications. Any divergence 51 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in 52 the latter. 53 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any 54 equipment declared to be in conformity with an IEC Publication. 55 6) All users should ensure that they have the latest edition of this publication. 56 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and 57 members of its technical committees and IEC National Committees for any personal injury, property damage or 58 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and 59 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC 60 Publications. 61 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is 62 indispensable for the correct application of this publication. 63 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of 64 patent rights. IEC shall not be held responsible for identifying any or all such patent rights. 65 International Standard IEC 61754-20-11 has been prepared by subcommittee 86B: Fibre optic 66 interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. 67 The text of this standard is based on the following documents: 68 FDIS Report on voting 86B/XX/FDIS 86B/XX/RVD 69 Full information on the voting for the approval of this standard can be found in the report on 70 voting indicated in the above table. 71 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 72 Licensed Copy: London South Bank University, London South Bank University, Fri Feb 15 06:55:10 GMT+00:00 2008, Uncontrolled Copy, (c) BSI 86B/2682/CD 4 The committee has decided that the contents of this publication will remain unchanged until 73 the maintenance result date1) indicated on the IEC web site under “http:/webstore.iec.ch“ in 74 the data related to the specific publication. At this date, the publication will be 75 reconfirmed, 76 withdrawn, 77 replaced by a revised edition, or 78 amended. 79 1) The National Committees are requested to note that for this publication the maintenance result date is Licensed Copy: London South Bank University, London South Bank University, Fri Feb 15 06:55:10 GMT+00:00 2008, Uncontrolled Copy, (c) BSI 86B/2682/CD 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS 80 - Fibre optic connector interfaces - 81 82 Part 20-11: Interface standard for LC connectors with protective housings 83 related to IEC 61076-3-106 84 1 Scope 85 This interface standard covers connectors with protective housings. These connectors use a 86 push-pull coupling mechanism. 87 To connect the fibres inside the housing the LC interface is used as described in IEC 61754-88 20. 89 The fully assembled variants (connectors) described in this document incorporate fixed and 90 free connectors. 91 2 Normative references 92 The following referenced documents are indispensable for the application of this document. 93 For dated references, only the edition cited applies.

For correct mating the intermateability is defined by the interface of the 114 LC-connector within the protective housing. For further details, see IEC 61754-20 and IEC 115 61706-3-106 variant 04. 116 Licensed Copy: London South Bank University, London South Bank University, Fri Feb 15 06:55:10 GMT+00:00 2008, Uncontrolled Copy, (c) BSI 86B/2682/CD 6 The connector housing according to IEC 61076-3-106 variant 04 provides a push-pull adaptor 117 connector interface. Inside this housing two LC-connectors are mountable, which provide a 118 duplex-interconnection with a mating counterpart. 119 Dimensions are given in millimetres; drawings are shown in first angle projection. The shape 120 of connectors may deviate from those shapes given in the following pictures as long as the 121 specified dimensions are not influenced. 122 5 Interfaces 123 Connector interfaces are in accordance with IEC 61754-20. This standard contains the 124 following standard interfaces: 125 Interface 11-1: duplex free plug connector interface PC 126 Interface 11-2: duplex fixed adaptor connector interface - PC 127 Int
