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 LC-PC simplex connector set (plug / adaptor / plug) must meet in order for it to be
categorised as an European 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 European 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
A simplex plug can be connected in a duplex adaptor without degrading the level of performance.

1.3 Operating environment
The tests selected combined with the severities and durations are representative of an external weather
protected environment defined by:

• ES 200 671 External weather protected environment defined by ES 300 019 classes 3.3, 3.4
and 3.5.
• EN 61753-2-1 Category U: uncontrolled environment

1.4 Reliability
Whilst the anticipated service life expectancy of the product in this environment is 20 years,
compliance with this European 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 European 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

amendments).
