18、TECHNICAL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 7-1: Type MPO connector family One fibre row FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
19、 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 Sp
20、ecifications, 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. Inter
21、national, governmental and non- governmental 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 fo
22、rmal 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
23、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.
24、 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 sh
25、all 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 cert
26、ification 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 in
27、jury, 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
28、 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 ident
29、ifying any or all such patent rights. International Standard IEC 61754-7-1 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This first edition of IEC 61754-7-1, along with the first edition of IEC 61754-7-
30、2, cancels and replaces the third edition of IEC 61754-7, published in 2008. This first edition of IEC 61754-7-1 includes the one fibre row MPO variants, including the addition of active device receptacles and up-angled plugs. The first edition of IEC 61754-7-2 will include the two fibre row MPO var
31、iants and related active device receptacles and up-angled plugs. 4 IEC 61754-7-1:2014 IEC 2014 Following the publication of both IEC 61754-7-1 and IEC 61754-7-2, IEC 61754-7 will be withdrawn. The text of this standard is based on the following documents: FDIS Report on voting 86B/3794A/FDIS 86B/382
32、6/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 61754 series, under the general title Fibr
33、e optic interconnecting devices and passive components fibre optic connector interfaces, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the
34、data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IEC 61754-7-1:2014 IEC 2014 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMP
35、ONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 7-1: Type MPO connector family One fibre row 1 Scope This part of IEC 61754 defines the standard interface dimensions for type MPO family of connectors with one row of fibres. 2 Description The parent connector for type MPO connector family is a multiway
36、plug characterized by a rectangular ferrule normally 6,4 mm 2,5 mm which utilizes two pins of 0,7 mm diameter as its alignment. The variant in this standard provides a joint of 2 to 12 fibres by arraying them between two pin-positioning holes in the ferrule in a one-layer, (one-row) arrangement. The
37、 connector includes a push-pull coupling mechanism and a ferrule spring loaded in the direction of the optical axis. The connector has a single male key which may be used to orient and limit the relative position between the connector and the component to which it is mated. Connector interfaces are
38、configured using a female plug without pins, a male plug with pins fixed and an adaptor as shown in Figure 1. The female plug is intermateable with the male plug. There are two angled-interface plugs, one called down-angled and the other up-angled. They are defined for both male and female plugs. Th
39、e up and down descriptors refer to the tilt direction of the ferrules angled end-face relative to the fibre axis when looking toward the end- face with the plugs key feature on the top. For down-angled plugs, the angled surface faces slightly downward. For up-angled plugs, the angled surface faces s
40、lightly upward. These different angles affect intermateability for the two adaptor types. An opposed keyway adaptor mates two plugs with the keys in opposite orientations, for example one side keyway-up and the other keyway-down. In contrast, an aligned keyway adaptor mates two plugs with the keys a
41、t the same orientation. When using an opposed keyway adaptor with angled interfaces, two down-angled plugs or two up-angled plugs are connected. For aligned keyway adaptors with angled interfaces, one down-angled plug and one up-angled plug are connected. Moreover, connector interfaces between the f
42、emale plug and the male plug are configured by applying a backplane housing and a printed board housing instead of the adaptor. Additionally, the female plug interface is intermateable with the active device receptacle. 3 Interfaces This standard contains the following standard interfaces: Interface
