Part 7: Type MPO connector family
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National 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 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 Organization
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 technical 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 order 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 clearly
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 Standard 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 1754-7 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
The text of this standard is based on the following documents:
FDIS Report on voting
86B/836/FDIS 86B/926/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

FIBRE OPTIC CONNECTOR INTERFACES –
Part 7: Type MPO connector family
1 Scope
This part of IEC 1754 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. 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.
Connector interfaces with different numbers of optical datum targets will intermate and will
correctly align the lower defined numbers of optical datum targets.
3 Interfaces
This standard contains the following standard interfaces.
Interface 7-1: MPO female plug connector angled interface – Push/pull
Interface 7-2: MPO male plug connector angled interface – Push/pull
Interface 7-3: MPO adaptor interface – Push/pull

NOTES
1 Each pin-hole shall accept a gauge pin as shown in figure 2c to a depth of 5,5 mm with a maximum force of 1,7 N.
In addition, two pin-holes of a plug shall accept a gauge as shown in figure 2d to a depth of 5,5 mm with a
maximum force of 3,4 N.
2 Dimension C is defined as the distance between two pin-hole centres.
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
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.
4 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 a position of the
coupling sleeve endface from datum Z is in the range of 0 to 0,1 mm.
5 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, a position of the coupling sleeve endface shall
be larger than 2,0 mm in the left direction from the datum Z.

NOTE – The optical datum target location diagram is shown in the figure. Here, datum X is defined as the line
passing through two pin-hole centres, and datum Y is defined as the line perpendicular to datum X and passing
through the midpoint of two pin-hole centres.

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

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.
Connector interfaces with different numbers of optical datum targets will intermate and will
correctly align the lower defined numbers of optical datum targets.
