30、ated and assembled singlemode resilient alignment sleeve LSH-APC 8 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 giv
31、en 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 sourc
32、e(s) of the product. When intermating plug variants 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 attenuati

34、ipated 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 g
35、uarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 2 Normative references The following referenced documents are indispensable for the application of this document.

45、amental tolerancing principle 3 Description The LSH-APC 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 mech
46、anism of the connectors is of a resilient sleeve style. 3.1 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
47、 connectors. The plug has mechanical and colour coding. BS EN 50377-8-12:2010EN 50377-8-12:2010 - 8 - 3.2 Adaptor The adaptor has a zirconia ceramic resilient alignment sleeve. The mounting style can be: - square flange 2 hole fixing; - square flange side clip fixing; - square flange top bottom clip
48、 fixing. Covers (dust caps) shall be provided to protect each port of the adaptor. The adaptor has a mechanical colour coding. 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
49、 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. 3.5 Colour and marking Marking of the product shall be in the following order of precedence: - identification of manufacturer; - ma
