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 61754-7-3 has been prepared by subcommittee 86B: Fibre optic

interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.

INTRODUCTION

The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed

that compliance with this document may involve the use of patents concerning MPO connectors.

The IEC takes no position concerning the evidence, validity and scope of this patent right.

The holders of these patent rights have assured the IEC that they are willing to negotiate

licences under reasonable and non-discriminatory terms and conditions with applicants

throughout the world. In this respect, the statement of the holders of these patent rights is

registered with the IEC. Information may be obtained from:

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.

ISO (www.iso.org/patents) and IEC (http://patents.iec.ch) maintain on-line data bases of

patents relevant to their standards. Users are encouraged to consult the data bases for the

most up to date information concerning patents.

This part of IEC 61754 defines the standard interface dimensions for type MPO family of

connectors with two rows of 16 fibres.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
No terms and definitions are listed in this document.

4 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 0,55 mm diameter as

its alignment. The variant in this document provides a joint of 32 fibres by arraying them

between two pin-positioning holes in the ferrule in a two-layer (two-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 shall be connected. For aligned keyway adaptors

with angled interfaces, one down-angled plug and one up-angled plug shall be connected.

Additionally, the female plug interface is intermateable with the active device receptacle.
