1 Scope

1.1 Product definition

This standard contains the initial, start of life dimensional, optical, mechanical and environmental performance
requirements which a terminated and assembled singlemode resilient alignment sleeve MU-PC simplex connector
set (plug adaptor plug) must meet in order for it to be categorised as an EN standard product.

Since different variants and grades of performance are permitted, product marking details are given in 3.5.

1.2 Intermateability

Although all products conforming to the requirements of this standard will intermate, the resulting level of
random attenuation performance will only be ensured in accordance with Table 1. The intention is that this will
be true irrespective of the manufacturing source(s) of the product.

In all cases, the intermating of plug variants having different attenuation or return loss grades will result in an
uncertain level of random attenuation performance. When intermating plug variants having different return loss
grades, the resulting level of return loss can not be assured to be any better than the worst return loss grade

Similarly, the intermating of a grade P plug with a grade Q plug will result in an uncertain level of random
attenuation performance.

Table 1 - Ensured level of random attenuation

Plug variant/Attenuation grade P Q
P P P
Q P Q


1.3 Operating environment

The tests selected combined with the severities and durations are representative of an EN 61753 Category U
environment and the ES 200 671 environment.

1.4 Reliability

Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this
standard does not guarantee the reliability of the product. This should be predicted using a recognised reliability
assessment programme.

1.5 Quality assurance

Compliance with this standard does not guarantee the manufacturing consistency of the product. This should be
maintained using a recognised quality assurance programme.

2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

3 Description

The MU-PC connector is a single position plug connector set of plug adaptor plug configuration characterised by
a cylindrical, spring loaded butting ferrule of 1,25 mm nominal diameter and a push-pull coupling mechanism.
The optical alignment mechanism of the connectors is of a resilient sleeve style

3.1 Plug

The plug features a cylindrical zirconia ferrule and a push-pull mechanism. It has a single male key which is used
to limit and may be used to orientate, the relative rotation between mated connectors.

A cover (dustcap) to protect the ferrule endface when the connector is in the unmated condition shall be
provided.

Alternative materials may be used for the ferrule that have directly compatible material properties to the specified
materials but the endface and performance requirements must be met under all conditions

3.2 Adaptor

The adaptor has a zirconia ceramic resilient alignment sleeve. The mounting styles are duplex rectangular flange
with snap-latches with a panel cut out as SC connector and simplex rectangular flange with snap-latches.

Covers (dustcaps) shall be provided to protect each port of the adaptor.

Alternative material may be used for the sleeve that have directly compatible material properties to zirconia but
the performance requirements must be met under all conditions

3.3 Materials

Materials which are not specified or which are not specifically described are left to the discretion of the
manufacturer.

3.4 Dimensions

Outline dimensions and other dimensions necessary to ensure intermateability or which affect performance are
specified. All other dimensions are left to the discretion of the manufacturer. Where the mating face limit
dimensions are not in agreement with an IEC Interface Standard this is clearly stated.

3.5 Colour and marking

Marking of the product shall be in accordance with 2.6.2 of EN 186000-1 in the following order of precedence:

a) identification of manufacturer;
b) manufacturing date code: year/week;
c) manufacturers part number;
d) variant identification number.

The following colour scheme is preferred:
