30、77-7-4:2011EN 50377-7-4:2011 6 1 Scope 1.1 Product definition This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements which a connector terminated with cylindrical zirconia PC ferrule and assembled singlemode resilient al

31、ignment sleeve LC-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 3.6. 1.2 Intermateability Although al

32、l 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

33、variants having different attenuation grades the resulting level of attenuation cannot be assured to be any better than the worst attenuation grade. Therefore, 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 l

34、evel of random attenuation Attenuation grade C B C C C B C B 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 internal weather protected env

35、ironment defined by EN 61753-1:2007, Category C. 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 reliab

36、ility 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. BS EN 50377-7-4:2011 7 EN 50377-7-4:2011 2 Normative references The foll

46、7-4:2011EN 50377-7-4:2011 8 3 Description 3.1 General The LC-PC simplex connector is a single position plug connector set of plug adaptor plug configuration characterised by cylindrical, spring loaded butting ferrules of 1,25 mm nominal diameter and a latched push-pull coupling mechanism. The optica

47、l alignment mechanism of the connectors is of a resilient sleeve style. 3.2 Plug The plug features a cylindrical zirconia ceramic ferrule and a latched 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. A

48、 cover (dust cap) to protect the ferrule endface when the connector is in the unmated condition shall be provided. Alternative materials may be used for the ferrule that have directly compatible material properties to zirconia but the endface and performance requirements must be met under all conditions 3.3 Adaptor The adaptor has a zirconia ceramic resilient alignment sleeve. The mounting styles are simplex rectangular flange equipped with snap-latches, duplex square flange equipped with snap-latches, and a duplex recta
