28、lignment sleeve LSH-PC simplex connector set (plug/adaptor/plug), adaptor and patchcord 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
29、 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. When intermating plug v
30、ariants having different attenuation grades, the resulting level of attenuation can not 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
31、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 U environment as defined in EN 61753-1. 1.4 Reliability Whilst the anticipated service life expectancy of the pro
32、duct 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
33、 the product. This should be maintained using a recognised quality assurance programme.

47、ion The LSH-PC connector is a single position plug connector set of plug/adaptor/plug configuration characterised by a cylindrical, spring loaded butting ferrule of 2,5 mm nominal diameter and a latched push-pull coupling mechanism. The optical alignment mechanism of the connectors is of a resilient
48、 sleeve style. 3.1 Plug The plug features a cylindrical composite ferrule using Cu-Ni-alloy 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. The plug has mechanical a
49、nd colour coding. Alternative materials may be used for the ferrule that have directly compatible material properties to the specified materials but the end face and performance requirements must be met under all conditions. 3.2 Adaptor The adaptor has a zirconia ceramic resilient alignment sleeve. The mounting style can be: i square flange - 2 hole fixing; ii square flange - side clip fixing ; iii square flange - top bottom clip fixing. Covers (dust caps) shall be provided to protect each port of the adapt
