24、16 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 31: Type N-FO connector family FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisinga
25、ll national electrotechnical committees (IEC National Committees). The object of IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, IEC publishes International Standards, Tec
26、hnical Specifications,Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IECPublication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interestedin the subject dealt with may participate in this preparatory work.
27、 International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closelywith the International Organization for Standardization (ISO) in accordance with conditions determined byagreement between the two organizations.2) The
28、formal decisions or agreements of IEC on technical matters express, as nearly as possible, an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from allinterested IEC National Committees.3) IEC Publications have the form of recommendations f
29、or international use and are accepted by IEC NationalCommittees in that sense. While all reasonable efforts are made to ensure that the technical content of IECPublications is accurate, IEC cannot be held responsible for the way in which they are used or for anymisinterpretation by any end user.4) I
30、n order to promote international uniformity, IEC National Committees undertake to apply IEC Publicationstransparently to the maximum extent possible in their national and regional publications. Any divergencebetween any IEC Publication and the corresponding national or regional publication shall be
31、clearly indicated inthe latter.5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformityassessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for anyservices carried out by independent certification b
32、odies.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 andmembers of its technical committees and IEC National Committees for any personal injury, property
33、 damage orother damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) andexpenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IECPublications.8) Attention is drawn to the Normative references cited in this pub
34、lication. Use of the referenced publications isindispensable 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 ofpatent rights. IEC shall not be held responsible for identifying any or all suc
35、h patent rights.International Standard IEC 61754-31 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: FDIS Report on voting 86B/3961/FDIS 86B/3

The committee has decided that the contents of this publication will remain unchanged until the stability date indica
38、ted on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be g120 reconfirmed,g120 withdrawn,g120 replaced by a revised edition, org120 amended.BS EN 61754-31:2016IEC 61754-31:2016 g164 IEC 2016 5 INTRODUCTION The Interna
39、tional Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with this document may involve the use of a patent concerning IEC 61754-31. IEC takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent right
40、has assured the IEC that he/she is willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with IEC. Information may be obtained from: Huberg14Suhn

46、scription 3.1 General The N-FO connector family comprises a two way and four way circular plug connector and socket set. The plug connector in each case includes a spring loaded threaded coupling nut and the plug shell features a single keyway which is used to orient it with a key in the socket with
47、 which it is being mated. The 1,25 mm non-angle polished ferrules used within the connectors are aligned using resilient sleeves housed within the plug. 3.2 Two way system This system consists of two spring loaded ferrules within each connector body. The pitch between the two fibre centres is nomina
48、lly 3,0 mm. It has a threaded coupling mechanism, which is designed to be tightened to a torque of 1 Nm to 2 Nm. 3.3 Four way system This system consists of four spring loaded ferrules in a row within each connector body. The pitch between any two adjacent fibre centres is nominally 2,50 mm. It has
49、a threaded coupling mechanism, which is designed to be tightened to a torque of 1 Nm to 2 Nm.
