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 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 certification 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 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.
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 identifying 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 61754-7-2, 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 variants and related active
device receptacles and up-angled plugs.

FIBRE OPTIC INTERCONNECTING
DEVICES AND PASSIVE COMPONENTS –
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 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
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.
There are two angled-interface plugs, one called down-angled and the other up-angled. They
are defined for both male and female plugs. The up and down descriptors refer to the tilt
direction of the ferrule’s angled end-face relative to the fibre axis when looking toward the end-
face with the plug’s key feature on the top. For down-angled plugs, the angled surface faces
slightly downward. For up-angled plugs, the angled surface faces slightly 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
at 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 female 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.

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 dimension I is variable. Ferrule compression force
shall 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.

The coupling sleeve shall be movable by a certain axial compression force. Dimension L is given for a coupling
sleeve end when not mated. Coupling sleeve compression force shall be 2,9 N to 6,9 N when the 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.
e
An adaptor coupling part shall be unlocked by a left-direction movement of a coupling sleeve, when it is separate
from an adaptor. When the coupling sleeve is moved for unlocking, the position of the coupling sleeve endface

Dimension I is defined at the centre line between the two pin-hole centres.
g
The mating/unmating force between an MPO plug and adaptor shall not exceed 30,0 N.
h
Dimensions D1 and U1 are defined only at the end of the plug as shown.
