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 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 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

Part 7: Type MPO connector family

1 Scope
This part of IEC 61754 defines the standard interface dimensions for type MPO family of
connectors.
2 Description
The parent connector for type MPO connector family is a multiway plug connector charac-
terized by a rectangular ferrule normally 6,4 mm × 2,5 mm which utilizes two pins of 0,7 mm
diameter as its alignment. It is applicable to a joint of multiple fibres up to 12 fibres by arraying
them between two pin-positioning holes in the ferrule. Furthermore, it is capable of joining up to
24 fibres by arraying them with a two layer arrangement. The 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 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.
Moreover, connector interfaces between the female plug and the male plug are configured by
applying a backplane housing and a printed board housing instead of the adaptor.

NOTE 1 Each guide-pin must be retained with a minimum force of 19,6 N. Surface roughness R must be
z
below 0,5 µm.
NOTE 2 Dimension C is defined as the distance between two guide-pin centres.
NOTE 3 Dimension I is given for a fibre endface centre of a plug end when not mated. It is noticed that a
ferrule is movable by a certain axial compression force, and therefore the dimension I is variable. Ferrule
compression force must be 7,8 N to 11,8 N when a position of the fibre endface from the datum Z is in the
range of 8,2 mm to 8,4 mm.
NOTE 4 Coupling sleeve must be movable by a certain axial compression force. Dimension L is given for
a coupling sleeve end when not mated. Coupling sleeve compression force must be 2,9 N to 6,9 N when a
position of the coupling sleeve endface from datum Z is in the range of 0 mm to 0,1 mm to the right or to
the left of datum Z.
NOTE 5 An adaptor coupling part must be unlocked by a movement away from the adaptor of a coupling
sleeve, when it is separate from the adaptor. When the coupling sleeve is moved for unlocking, a position
of the coupling sleeve endface must be larger than 2,0 mm in the left direction from the datum Z.

NOTE 6 The top shape of guide-pin may be a round shape that is symmetrical about the guide-pin axis
with a minimum radius of 0,15 mm.

NOTE 1 In the figure of cross-section G-G, the inner housing must be movable to the right at least 0,9 mm under
the condition that the inner latch is completed. In addition, the inner housing must be movable at least 2 mm to the
left when the inner latch is released.
NOTE 2 In the figure of expanded cross-section I, the inner latch spring must be moved by more than 0,65 mm to
the right when the inner latch is released or latched.

AVANT-PROPOS
1) La Commission Électrotechnique Internationale (CEI) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. A cet effet, la CEI – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de la CEI"). Leur élaboration est confiée à des comités d'études,
aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participent également aux
travaux. La CEI collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux intéressés
sont représentés dans chaque comité d’études.
3) Les publications CEI se présentent sous la forme de recommandations internationales et elles sont agréées
comme telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI
s'assure de l'exactitude du contenu technique de ses publications; la CEI ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de la CEI s'engagent à appliquer de
façon transparente, dans toute la mesure possible, les publications de la CEI dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI n’a fixé aucune procédure concernant le marquage comme indication d’approbation et sa responsabilité
n’est pas engagée quand un matériel est déclaré conforme à l’une de ses normes.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à la CEI, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités
nationaux de la CEI, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre
dommage de quelque nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais
de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de la CEI ou de
toute autre Publication de la CEI, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références Normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
La Commission Electrotechnique Internationale (CEI) attire l'attention sur le fait qu'il est déclaré que la conformité

avec les dispositions du présent document peut impliquer l'utilisation d'un brevet intéressant les connecteurs de
type MPO.
La CEI ne prend pas position quant à la preuve, à la validité et à la portée de ces droits de propriété.
Le détenteur de ces droits de propriété a donné l'assurance à la CEI qu'il consent à négocier des licences avec des
demandeurs du monde entier, soit sans frais soit à des termes et conditions raisonnables et non discriminatoires. À
ce propos, la déclaration du détenteur des droits de propriété est enregistrée auprès de la CEI. Des informations
