30、tial, start of life dimensional, optical, mechanical and environmental performance requirements which a connector terminated with cylindrical zirconia 8 angled PC ferrule and assembled singlemode resilient alignment sleeve SC-APC simplex connector set (plug/adaptor/plug), adaptor and patchcord must
31、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 3.6. 1.2 Intermateability Although all products conforming to the requirements of this standard will intermate, the resulting level
32、 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 ass
33、ured 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.

34、e tests selected combined with the severities and durations are representative of a category U environment described 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 standard does not guarantee the reli
35、ability 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 the product. This should be maintained using a recognised quality assurance programme. BS EN 5

45、50377-4-2:2011EN 50377-4-2:2011 8 3 Description 3.1 General The SC-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
46、 alignment mechanism of the connectors is of a resilient sleeve style. 3.2 Plug The plug features a cylindrical zirconia ceramic ferrule and a push-pull coupling mechanism. The plug housing has a single male key, which is used to limit the relative rotation between mated plugs. A cover (dust cap) to
47、 protect the ferrule end face when the connector is in the unmated condition shall be provided. 3.3 Adaptor The adaptor has a zirconia ceramic resilient alignment sleeve. The mounting style is a rectangular flange simplex. Covers (dust caps) are provided to protect each port of the adaptor. 3.4 Mate
48、rials 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 IEC Interface Standard this is clearly stated. 3.6 Colour and marking Marking of the product shall be i
