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 LF3 APC
8° simplex connector set (plug-adaptor-plug), adaptor and patchcord will 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 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.
When intermating plug variants having different attenuation grades, the resulting level of attenuation cannot be
assured to be any better than the worst attenuation grade.
The intermating of a grade C plug with a grade B plug will result in an uncertain level of random attenuation
performance.
Table 1 - Ensured level of random attenuation
Plug variant/Attenuation grade C B
C C C
B C B

1.3 Operating environment
The tests selected combined with the severities and durations are representative of a Category C environment
as defined in EN 61753-1.
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.

3 Description
3.1 General
The LF3 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 latched push-
pull coupling mechanism. The optical alignment mechanism of the connectors is of a resilient sleeve style.
3.2 Plug
The plug features a cylindrical composite ferrule using titanium as fibre surrounding material 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.
3.3 Adaptor
The adaptor has a zirconia ceramic resilient alignment sleeve. The mounting styles are simplex rectangular
flange equipped with snap-latches or screws, and duplex rectangular flange with snap-latches or screws.
Covers (dust caps) shall be provided to protect each port of the adaptor.
3.4 Materials
Materials which are not specified or which are not specifically described are left to the discretion of the
manufacturer.
3.5 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 EN Interface Standard this is clearly stated.
