Part 7: Type MPO connector family

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.
The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance
with this document may involve the use of a patent concerning MPO connectors.

The IEC takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured the IEC that he/she is willing to negotiate licences under reasonable and
non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the
holder of this patent right is registered with the IEC. Information may be obtained from:
Intellectual Property Department,
Nippon Telegraph and Telephone Corporation,
20-2 Nishi-shinjuku 3-Chome Shinjukuku,
Tokyo 163-14, Japan.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights
other than those identified above. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61754-7 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.

This third edition cancels and replaces the second edition published in 2004. This third edition
constitutes a technical revision.

Specific technical changes involve the addition of an aligned key adaptor interface definition to
address all existing MPO applications.

The text of this standard is based on the following documents:

CDV Report on voting
86/2581/CDV 86/2672/RVC
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 Fibre 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
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the 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.

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.
