27、tical, mechanical and environmental performance requirements which a terminated and assembled singlemode resilient alignment sleeve LSH-APC simplex connector set (plug/adaptor/plug), adaptor and patchcord must meet in order to be categorised as an EN standard product. Since different variants and gr

28、ades of performance are permitted, product marking details are given 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

29、 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 can not be assured to be any better than the worst attenuation grade. The intermating of a grade C plug with a

30、 grade B plug will result in an uncertain level of random attenuation performance.

31、nvironment 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 standard does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment prog

32、ramme. 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. EN 50377-8-2:2007 - 6 - 2 Normative references The following referenced documents are indispensable fo

49、pling mechanism. The optical alignment mechanism of the connectors is of a resilient 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 and colour coding. Alternative materials may be used for the ferrule that have directly compatible material properties t
