FIBRE OPTIC CONNECTOR INTERFACES −
Part 6: Type MU 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 61754-6 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/881/FDIS 86B/983/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.
Annexes A and B are for information only.

FIBRE OPTIC CONNECTOR INTERFACES –
Part 6: Type MU connector family
1 Scope
This part of IEC 61754 defines the standard interface dimensions for type MU family of
connectors.
2 Description
The parent connector for type MU connector family is a miniature single-position plug which is
characterized by a cylindrical, spring-loaded butting ferrule(s) of a 1,25 mm typical diameter,
and a push-pull coupling mechanism. The optical alignment mechanism of the connectors is of
a rigid hole or a resilient sleeve style.
3 Interfaces
This standard contains the following standard interfaces.
Interface 6-1: Simplex plug connector interface – Push/pull
Interface 6-2: Duplex plug connector interface – Push/pull
Interface 6-3: Simplex adaptor connector interface – Push/pull
Interface 6-4: Duplex adaptor connector interface – Push/pull
Interface 6-5: 8-port adaptor connector interface – Push/pull
Interface 6-6: Plug connector interface – for printed board housings
Interface 6-7: Sleeve holder interface – for printed board housings
Interface 6-8: 2-port backplane housing interface – Self-retentive
Interface 6-9: 2-port printed board housing interface – Self-retentive
Interface 6-10: 8-port backplane housing interface – Self-retentive
Interface 6-11: 8-port printed board housing interface – Self-retentive
The plugs of interfaces 6-1, 6-2 and 6-6 have a ferrule(s) with a spherically polished ferrule
endface, and realize physical contact.
The type MU connector family comprises two types of connector set: MU-A connector set (see
annex A) and MU-B connector set (see annex B). The MU-A connector set is a plug/adaptor
configuration with a push-pull coupling mechanism. The MU-B connector set is a plug-in type
back-plane connector configuration which is plug/backplane and printed board housings/plug
for printed board housing/sleeve holder configuration and is equipped with a self-retentive
mechanism.
The type MU-A connector set consists of simplex and duplex plugs, and simplex, duplex and 8-port
adaptors. The plugs are common to the backplane connector housings of the type MU-B connector
set.
---------------------- Page: 7 ----------------------
61754-6 IEC:1997 – 9 –
The type MU-B connector set consists of 2-port and 8-port backplane and printed board
connector housings, simplex and duplex plugs, plug for printed board connector housings, and
sleeve holder. The plug for printed board connector housing is used as a jack together with the
sleeve holder. The jack is attached into the printed board connector housing.
The following standard interfaces are intermateable.

NOTES
1 A chamfer or radius is allowed to a maximum depth of 0,5 mm from the ferrule endface.
2 The coupling sleeve shall be movable toward the right and the left directions. These
dimensions are given when the coupling sleeve is moved in its most right-direction position.
3 The dimension J is given for the plug endface when not mated. It is noticed that the ferrule is
movable by a certain axial compression force with direct contacting endfaces, and therefore the
dimension J is variable. Ferrule compression force shall be 5,5 N to 6,5 N when the position of
the optical datum target from the datum X is moved in the range of 3,9 mm to 4,1 mm. In
addition, the dimension J shall become less than 3,25 mm with a relatively large axial
compression force.
4 The right-side position of Q shall become the left-side position to the plane defined by
datum X when the coupling sleeve is moved to its most left-direction position.
5 Dome eccentricity of the spherically polished ferrule endface shall be less than 50 μm.
