22、96 IEC 1996 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ FIBRE OPTIC CONNECTOR INTERFACES Part 3: Type LSA connector family FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Nation
23、al 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 end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical
24、committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organiz
25、ation for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technic
26、al committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In orde
27、r to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be c
28、learly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment 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 Stan
29、dard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61754-3 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre op
30、tics. This bilingual version (2014-03) corresponds to the monolingual English version, published in 1996-12. The text of this standard is based on the following documents: FDIS Report on voting 86B/834/FDIS 86B/924/RVD Full information on the voting for the approval of this standard can be found in
31、the report on voting indicated in the above table. The French version of this standard has not been voted upon. 4 IEC 61754-3:1996 IEC 1996 FIBRE OPTIC CONNECTOR INTERFACES Part 3: Type LSA connector family 1 Scope This part of IEC 61754 defines the standard interface dimensions for type LSA family
32、of connectors. 2 Description The parent connector for type LSA connector family is a single position plug connector which is characterized by a 2,5 mm nominal ferrule diameter. It includes a screw coupling nut and a ferrule spring load in the direction of the optical axis. The plug has a single male
33、 key which may be used to orient and limit the relative rotation between the connector and the component to which it is mated. 3 Interfaces This standard contains the following standard interfaces: Interface 3-1: Plug connector interface Screw coupling Interface 3-2: Adaptor connector interface Scre
34、w coupling Interface 3-1 mates with interface 3-2.

41、Famille de connecteurs de type LSA AVANT-PROPOS 1) La CEI (Commission lectrotechnique Internationale) est une organisation mondiale de normalisation compose de lensemble des comits lectrotechniques nationaux (Comits nationaux de la CEI). La CEI a pour objet de favoriser la coopration internationale
42、pour toutes les questions de normalisation dans les domaines de llectricit et de llectronique. A cet effet, la CEI, entre autres activits, publie des Normes internationales. Leur laboration est confie des comits dtudes, aux travaux desquels tout Comit national intress par le sujet trait peut partici
43、per. Les organisations internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participent galement aux travaux. La CEI collabore troitement avec lOrganisation Internationale de Normalisation (ISO), selon des conditions fixes par accord entre les deux organisations. 2) Les
44、 dcisions ou accords officiels de la CEI concernant les questions techniques reprsentent, dans la mesure du possible, un accord international sur les sujets tudis, tant donn que les Comits nationaux intresss sont reprsents dans chaque comit dtudes. 3) Les documents produits se prsentent sous la form
45、e de recommandations internationales. Ils sont publis comme normes, rapports techniques ou guides et agrs comme tels par les Comits nationaux. 4) Dans le but dencourager lunification internationale, les Comits nationaux de la CEI sengagent appliquer de faon transparente, dans toute la mesure possibl
46、e, les Normes internationales de la CEI dans leurs normes nationales et rgionales. Toute divergence entre la norme de la CEI et la norme nationale ou rgionale correspondante doit tre indique en termes clairs dans cette dernire. 5) La CEI na fix aucune procdure concernant le marquage comme indication
47、 dapprobation et sa responsabilit nest pas engage quand un matriel est dclar conforme lune de ses normes. 6) Lattention est attire sur le fait que certains des lments de la prsente Norme internationale peuvent faire lobjet de droits de proprit intellectuelle ou de droits analogues. La CEI ne saurait
48、 tre tenue pour responsable de ne pas avoir identifi de tels droits de proprit et de ne pas avoir signal leur existence. La Norme internationale CEI 61754-3 a t tablie par le sous-comit 86B: Dispositifs dinterconnexion et composants passifs fibres optiques, du comit dtudes 86 de la CEI: Fibres optiques.
