26、nical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this
27、 end and in addition to other activities, the IEC publishes International Standards. 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 non-governmental orga
28、nizations liaising with the IEC also participate in this preparation. The 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 the IEC on te
29、chnical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published
30、 in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum exten
31、t possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equi
32、pment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Stan
33、dard IEC 61754-18 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This bilingual version (2014-03) corresponds to the monolingual English version, published in 2001-12. The text of this standard is based
34、on the following documents: FDIS Report on voting 86B/1594/FDIS 86B/1627/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. The French version of this standard has not been voted upon. This publication has been draf
35、ted in accordance with the ISO/IEC Directives, Part 3. The committee has decided that the contents of this publication will remain unchanged until 2004. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 4 IEC 61754-18:2001 IEC 2001 FIBRE OPTIC C
36、ONNECTOR INTERFACES Part 18: Type MT-RJ connector family 1 Scope This part of IEC 61754 defines the standard interface dimensions for the type MT-RJ family of connectors. 2 Description The parent connector for the type MT-RJ connector family is a plug connector having single or multiple fibres in a
37、rectangular ferrule nominally 4,4 mm 2,5 mm aligned by two 0,7 mm diameter pins and corresponding holes. The connector includes a single coupling latch and a ferrule spring loaded in the direction of the optical axis. The plug connector has a single male key which may be used to orientate the connec
38、tor and the component to which it is mated. Connector interfaces are configured as a plug without pins, an adaptor and a plug with pins or alternatively as a plug without pins and a receptacle with pins. Adaptors use ribs to pre-align ferrules. Receptacles with and without ribs are defined. 3 Interf
39、aces Subsequent pages define the standard interfaces for the type MT-RJ connector family. This standard contains the following standard interfaces: Interface 61754-18-1 MT-RJ plug connector interface, without pins, consisting of Interface 61754-18-1-1 for single fibre Interface 61754-18-1-2 for two
40、fibres with a pitch of 0,25 mm Interface 61754-18-1-3 for two fibres with a pitch of 0,75 mm Interface 61754-18-1-4 for four fibres with a pitch of 0,25 mm Interface 61754-18-2 MT-RJ plug connector interface, with pins, consisting of Interface 61754-18-2-1 for single fibre Interface 61754-18-2-2 for
41、 two fibres with a pitch of 0,25 mm Interface 61754-18-2-3 for two fibres with a pitch of 0,75 mm Interface 61754-18-2-4 for four fibres with a pitch of 0,25 mm Interface 61754-18-3 MT-RJ adaptor interface Interface 61754-18-4 MT-RJ receptacle interface, with pins, without ribs, consisting of Interf
