family FOREWORD 1) The International 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 electronic 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 committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work International, governmental and nongovernmental 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) 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 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 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 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 some 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 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 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 possibility 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 61754-34 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics The text of

Electropedia: available at http://www.electropedia.org/ – ISO Online browsing platform: available at http://www.iso.org/obp Description The parent connector for the type URM connector family is a duplex connector set of plug/adaptor/plug configuration which is characterized by a 1,25 mm nominal diameter ferrule The plug connector includes two spring loaded ferrules in the direction of the optical axis The plug also has a single male key, which may be used to orientate and limit the relative position between the connector and the adaptor to which it is mated The optical alignment mechanism of the connectors is a resilient sleeve Drawings and dimensions provided consist of those minimum features that are functionally critical during the mating and unmating sequences of the plug with its adaptor counterpart component Interfaces General requirements defined in IEC 61754-1 shall be used for this document BS EN 61754-34:2016 IEC 61754-34:2016 © IEC 2016 – 18 – Table – Dimensions

certain axial compression force, with direct contacting endface, and therefore dimension H1 is variable Ferrule compression force shall be 5,0 N to 6,0 N when the position of the optical datum target, dimension H1, is moved to the range from 4,8 mm to 5,1 mm Forces are for buffered fibre only; different cord constructions can result in higher forces (see IEC 60794-2-50) b These dimensional requirements apply to the finished ferrule after all polishing procedures have been completed c The outer housing shall be movable to the left and to the right These dimensions are given when the release case has been moved to the farthest left position d When the outer housing has been moved in the farthest right position, the inner housing shall protrude from the outer housing e Dimension AM is defined as an angle between two planes One plane, plane C, passes through the axis parallel to the axes of the ferrules and the axis of symmetry of the key of the angled endface plug connector The other plane, plane D, passes through the axes of the ferrules and the plane normal to the angled PC reference plane BS EN 61754-34:2016 IEC 61754-34:2016 © IEC 2016 – 19 – Ferrule grade dimensions
