1 Scope
1.1 Product definition
This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements which a terminated and assembled singlemode resilient alignment sleeve MU-APC 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 Section 3.5.
1.2 Intermateability
Although all products conforming to the requirements of this specification 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 IEC 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 specification 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 specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme.

3 Description
The MU-APC
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:
